Dry Eye Syndrome: Causes, Symptoms & Best Treatment in Dhaka (2026)

Dry eye is the most under-diagnosed condition I see in my clinic. Patients come to me for LASIK or cataract surgery consultations; I examine their tear film, and I find dry eye disease that has been quietly causing discomfort for months or years — often attributed to “eye strain,” “too much screen time,” or “Dhaka’s air quality.”

Dry eye syndrome in Bangladesh is extremely common — and it is getting more prevalent. Air conditioning in offices and homes, smartphones and screens, contact lens overuse, increasing pollution, and a rising rate of diabetes all contribute to a city that is quietly hard on tear films. Understanding what dry eye actually is — and what genuinely helps — is what this article is for.

What is Dry Eye Syndrome?

Dry eye syndrome (DES) — clinically called Dry Eye Disease (DED) — is a chronic condition of the ocular surface in which the eye either does not produce enough tears, or produces tears of insufficient quality to maintain a stable, protective tear film over the cornea.

Dry eye syndrome affects approximately 10% of people between the ages of 30 and 60, and 15% of adults over age 65. In urban Bangladesh — with its combination of air conditioning, high screen exposure, contact lens use, and pollution — the prevalence is likely significantly higher.

The tear film has three critical layers:

  • Lipid layer (outermost) — produced by the Meibomian glands in the eyelids; prevents tear evaporation
  • Aqueous layer (middle) — produced by the lacrimal gland; provides hydration and nutrients
  • Mucin layer (innermost) — produced by goblet cells; helps tears adhere to the corneal surface

A breakdown in any of these three layers — most commonly the lipid layer — results in an unstable tear film, increased evaporation, and the symptoms of dry eye disease.

The Two Types of Dry Eye — Why This Matters for Treatment

Understanding which type of dry eye you have determines which treatment will actually work. Many patients spend years using the wrong drops for the wrong type.

Type 1 — Aqueous Deficient Dry Eye (ADDE)

The lacrimal gland does not produce enough watery tears. Accounts for approximately 10–20% of dry eye cases. Associated with autoimmune conditions (Sjögren’s syndrome, rheumatoid arthritis, lupus), certain medications (antihistamines, antidepressants, beta-blockers), and post-LASIK nerve damage.

Type 2 — Evaporative Dry Eye (EDE)

The most common type — accounting for 80% of dry eye disease. Caused by Meibomian Gland Dysfunction (MGD), where the eyelid glands fail to secrete sufficient lipid, causing the tear film’s protective layer to thin and tears to evaporate too quickly.

In Dhaka specifically, evaporative dry eye is dominant — driven by air conditioning, screen exposure, contact lens overuse, and environmental pollution.

“When a patient tells me their eyes are dry and burning in an air-conditioned office, their first instinct is to buy lubricating drops from a pharmacy. That helps temporarily — but it does not address why the tears are evaporating. In most cases, the answer is Meibomian Gland Dysfunction, and that requires a specific treatment approach — not just more drops.”
— Dr. Ashraful Huq

What Causes Dry Eye in Dhaka?

Environmental Factors

  • Air conditioning — the single biggest dry eye trigger in Dhaka’s office and home environments; dramatically reduces ambient humidity and increases tear evaporation
  • Pollution and particulate matter — Dhaka’s dust, vehicle emissions, and industrial particulates irritate the ocular surface and destabilise the tear film
  • Seasonal changes — winter months reduce humidity further; summer heat increases evaporation

Lifestyle Factors

  • Screen use — reduces blink rate by up to 60%, leading to inadequate tear film renewal and increased evaporation
  • Contact lens wear — lenses disrupt tear film stability; long wearing hours and poor hygiene accelerate Meibomian gland changes
  • Incomplete blinking — during focused screen work, many people partially blink, preventing full spreading of the lipid layer across the cornea

Medical Factors

  • Diabetes — damages nerves supplying the lacrimal gland and corneal surface, reducing both tear production and corneal sensitivity
  • Thyroid eye disease — causes incomplete eyelid closure and corneal exposure
  • Autoimmune conditions — Sjögren’s syndrome, rheumatoid arthritis, and lupus directly affect lacrimal gland function
  • Vitamin A deficiency — affects goblet cell density and mucin production
  • Post-LASIK nerve disruption — corneal nerve damage after LASIK reduces the reflex arc driving lacrimal secretion. This is why I recommend SMILE surgery for patients with pre-existing dry eye — SMILE preserves significantly more corneal nerve fibres. For patients with severe dry eye, ICL surgery — which does not touch the cornea at all — carries essentially zero dry eye risk

Medications That Worsen Dry Eye

  • Antihistamines (common in Bangladesh for allergy)
  • Antidepressants and antipsychotics
  • Beta-blockers and diuretics
  • Oral contraceptives
  • Isotretinoin (acne treatment)

Symptoms of Dry Eye Syndrome

Dry eye symptoms are frequently misattributed to “tired eyes” or “phone addiction.” The specific symptoms are:

  • Burning, stinging, or scratching sensation — worst in air-conditioned environments
  • Redness that worsens through the day
  • Gritty sensation — as if something is in the eye
  • Blurred vision that fluctuates and clears with blinking
  • Sensitivity to wind, smoke, or air conditioning
  • Difficulty wearing contact lenses for extended periods
  • Eye fatigue during prolonged reading or screen use

The paradox symptom — watery eyes: Many dry eye patients present with excessive watering. This occurs because the unstable tear film triggers a reflex watering response — but reflex tears lack the lipid component needed to stabilise the tear film, so the eye remains dry despite the watering.

How Dry Eye is Diagnosed

A proper tear film assessment is essential before treatment is prescribed. Guessing the type and prescribing the wrong drops is one of the most common causes of treatment failure. At BEH, my assessment includes:

Tear Film Tests:

  • TBUT (Tear Break-Up Time) — normal >10 seconds; <5 seconds indicates significant instability
  • Schirmer’s test — measures aqueous tear production; <5 mm indicates aqueous deficiency
  • Meniscometry — measures tear meniscus height at the lower eyelid margin
  • Fluorescein staining — reveals areas of corneal surface damage

Meibomian Gland Assessment:

  • Slit-lamp lid examination — assesses gland orifice plugging, lid margin irregularity, and meibum quality
  • Meibography — infrared imaging to visualise gland structure and identify permanent gland dropout

Ocular Surface Assessment:

  • Lissamine green staining — reveals conjunctival surface damage not visible with fluorescein
  • Corneal sensitivity testing — reduced in post-LASIK and diabetic patients

Best Treatment for Dry Eye in Dhaka — What Actually Works

Treatment must be matched to the type and severity of dry eye. There is no single drop that works for everyone.

Step 1 — Artificial Tears and Lubricating Drops

  • Carboxymethylcellulose (CMC) drops — e.g. Refresh, Tears Naturale. Good for aqueous-deficient dry eye. Widely available in Bangladesh
  • Sodium hyaluronate drops — e.g. Hycosan, Hylo-Forte. Superior retention time on the ocular surface; preferred for evaporative dry eye
  • Lipid-containing drops — e.g. Systane Balance, Clinitas Soothe. The correct choice for most Dhaka patients with MGD; replenishes the deficient lipid layer
  • Preservative-free drops — essential for patients using drops more than 4 times daily; preservatives in multi-dose bottles cause ocular surface toxicity with frequent use

“The most common mistake I see is patients using whichever drop is most prominently stocked at their local pharmacy — usually a CMC-based drop — for what is actually Meibomian gland dysfunction. What they need is lipid replacement, warm compression, and lid hygiene. Drops alone will not solve MGD.”
— Dr. Ashraful Huq

Step 2 — Warm Compression and Lid Hygiene

For Meibomian Gland Dysfunction — the most important non-drop treatment.

10 minutes of warm compression (40–45°C) twice daily softens the thickened meibum inside the Meibomian glands. Follow with lid massage and lid hygiene — cleaning lid margins with diluted baby shampoo or commercial lid wipes (e.g. Blephaclean). This combination is the most effective and most affordable first-line treatment for MGD-driven dry eye.

Step 3 — Anti-inflammatory Treatment

In moderate to severe dry eye, inflammation of the ocular surface is both a cause and a consequence of tear film instability:

  • Topical cyclosporine A (0.05%) — e.g. Restasis. Reduces ocular surface inflammation and increases goblet cell density. Takes 3–6 months for full effect
  • Short-course topical steroids — 2–4 week course of loteprednol for acute flares, bridging to cyclosporine. Requires IOP monitoring. Never self-prescribed
  • Omega-3 supplementation — 2–3g EPA/DHA daily improves Meibomian gland secretion quality; results after approximately 3 months of consistent use

Step 4 — Environmental and Lifestyle Modification

  • Reduce AC exposure where possible; use a humidifier in the office or bedroom
  • Apply the 20-20-20 rule during screen use — every 20 minutes, look at something 20 feet away for 20 seconds and blink fully
  • Adjust screen position below eye level to reduce exposed ocular surface area and slow evaporation
  • Limit contact lens wear to 8–10 hours maximum; switch to daily disposables
  • Stay hydrated — systemic dehydration reduces aqueous tear production

Step 5 — Advanced Treatments for Severe Cases

  • Punctal plugs — tiny silicone plugs inserted into tear drainage openings, increasing tears on the ocular surface. Simple and reversible
  • Autologous serum eye drops — made from the patient’s own blood serum; contains growth factors and proteins that closely mimic natural tears; particularly effective in severe aqueous deficient dry eye and post-LASIK cases
  • Intense Pulsed Light (IPL) therapy — targets abnormal blood vessels contributing to Meibomian gland inflammation; strong clinical evidence for MGD
  • Meibomian gland probing and expression — mechanical opening of blocked gland orifices under slit-lamp

Dry Eye and Vision Correction Surgery — What Every Patient Must Know

LASIK can worsen pre-existing dry eye. The corneal flap severs nerves driving lacrimal secretion — post-LASIK dry eye affects an estimated 20–40% of patients in the first 3–6 months and can persist longer in those with pre-existing disease.

For patients with significant dry eye considering vision correction, I recommend SMILE or ICL depending on their eye profile — both carry substantially lower dry eye risk than LASIK. If you have dry eyes and are considering any refractive procedure, thorough pre-operative tear film assessment is not optional.

Dr. Ashraful Huq’s Clinical Perspective

Dry eye is one of those conditions where the gap between patient suffering and available treatment is entirely unnecessary. Most patients with dry eye in Dhaka have never had a proper tear film assessment — they have simply been buying drops and managing symptoms on their own.

The majority of cases I see are driven by Meibomian gland dysfunction — a condition that responds well to warm compression, lid hygiene, lipid-replacement drops, and omega-3 supplementation. These are simple, inexpensive interventions. Patients who have been suffering for years often see significant improvement within 4–6 weeks of a correct diagnosis and proper treatment plan.

If your eyes are regularly burning, gritty, or tired — especially in air-conditioned environments or after screen use — do not assume it is simply “Dhaka’s air.” Come for a proper assessment. In most cases, the treatment is simpler than you expect.

Frequently Asked Questions

What is the best eye drop for dry eye in Bangladesh?
The best drop depends on your type of dry eye. For Meibomian gland dysfunction, lipid-containing drops such as Systane Balance or Clinitas Soothe are most appropriate. For aqueous-deficient dry eye, sodium hyaluronate provides superior retention. Preservative-free drops are essential if using drops more than 4 times daily.

Can dry eye be cured permanently?
Dry eye is a chronic condition managed rather than cured in most patients. However, consistent treatment with warm compression, lid hygiene, appropriate drops, and lifestyle modification achieves excellent long-term symptom control for the majority of patients.

Does air conditioning cause dry eye?
Yes. Air conditioning is the primary environmental driver of dry eye in Dhaka — it reduces humidity and accelerates tear evaporation, particularly in patients with Meibomian gland dysfunction. Using a humidifier alongside AC and taking regular breaks significantly reduces this effect.

Can I have LASIK if I have dry eyes?
It depends on severity. Significant dry eye is a contraindication to LASIK — but not to SMILE (lower dry eye risk) or ICL surgery (no corneal involvement). Dr. Ashraful Huq assesses tear film thoroughly before recommending any refractive procedure. Read more: LASIK vs SMILE vs ICL — which is right for you?

Is dry eye related to screen use?
Yes. Screen use reduces blink rate by up to 60%, causing incomplete tear film spreading and increased evaporation. The 20-20-20 rule and conscious full blinking during screen use significantly reduces this effect.

How long does dry eye treatment take to work?
Lubricating drops provide immediate temporary relief. Warm compression and lid hygiene show improvement within 4–6 weeks of consistent use. Cyclosporine A takes 3–6 months for full effect. Omega-3 supplementation takes approximately 3 months. Consistency is the most important factor.

Color Blind Lens in Bangladesh: Can Color Blindness Be Corrected?

Of all the questions patients bring to me about vision, questions about color blindness carry a particular weight. Because unlike asking about glasses or laser surgery — where the solution is relatively straightforward — color blindness sits in a different category. It is usually present from birth. It is inherited. It cannot be cured. And for years, patients in Bangladesh had almost nowhere to turn for honest, medically grounded information about whether anything could be done.

That is changing.

Color blind lenses — both spectacle lenses and contact lenses with specialised optical filters — are now available in Bangladesh and offer real, measurable benefit for many patients with color vision deficiency. But I also want to be honest with you about what they can and cannot do. You deserve a clear answer, not a sales pitch.

This article covers exactly what color blindness is, how color blind lenses work, who they help and who they do not, what you can realistically expect, and how to access assessment and prescription in Bangladesh.

What is Color Blindness? — The Correct Term is Color Vision Deficiency

Let me start with the science, because understanding it changes how you think about the available solutions.

A normal human eye sees three primary colors: red, green and blue. All other colors are the result of mixtures of these three. When a person has Color Vision Deficiency, one or more of the three primary colors is not detected correctly — reducing the number of color shades visible and slowing comprehension and reaction time. Source: Medical News Today

The photoreceptor cells responsible for color detection are called cones, and there are three types — each sensitive to a different range of wavelengths. In a color vision deficient eye, one or more cone types either function abnormally or overlap excessively in their sensitivity range with a neighbouring cone type, causing colors that should be distinct to appear similar or identical.

Color vision deficiency (CVD) is the clinically precise term. “Color blindness” is the common name — and it is slightly misleading, because the vast majority of people with CVD are not completely blind to color. They see color — just less of it, or less accurately than people with normal trichromatic vision.

Types of color vision deficiency:

Type Cones Affected What it Looks Like
Deuteranomaly Green cones — reduced sensitivity Most common; red-green confusion; greens look more red
Protanomaly Red cones — reduced sensitivity Reds appear darker and less distinct; red-green confusion
Deuteranopia Green cones — absent Severe red-green confusion; can’t distinguish many reds and greens
Protanopia Red cones — absent Severe; reds may appear nearly black; very limited red spectrum
Tritanomaly / Tritanopia Blue cones — reduced or absent Blue-yellow confusion; much rarer; often acquired rather than inherited
Achromatopsia All three cone types non-functional True complete color blindness — extremely rare

How common is it in Bangladesh?

Color vision deficiency affects approximately 8% of males and 0.5% of females of all ethnicities globally — making it one of the most common inherited conditions affecting vision. In a country of 170 million people, this means an estimated 6–7 million Bangladeshis live with some form of CVD. The vast majority are undiagnosed — many simply adapting without ever knowing the clinical name for what they experience.

How Color Blind Lenses Work — The Science Explained Honestly

This is the section I want to be most careful about — because there is a great deal of marketing language around color blind lenses that can give patients unrealistic expectations.

Color blind glasses use tinted filters to shift how reds and greens appear to people with red-green color blindness. They do not cure color blindness. Peer-reviewed studies show results that vary by person, deficiency type, and the test being used.

Here is the honest mechanism:

The most common form of red-green color blindness involves an excessive overlap between the sensitivity curves of the red and green cone photoreceptors. Because these two types of cones respond to too similar a range of wavelengths, the brain receives ambiguous signals — red and green look similar because they both stimulate both types of cones almost equally.

Color blind lenses work by blocking narrow bands of light — mostly in the 530 to 560 nm range where red and green cone responses overlap most. Cutting that overlap is meant to increase the contrast between red and green signals, so colors that normally look similar become easier to tell apart. This is contrast enhancement, not correction — the lenses do not repair the underlying cone cells. They change the light that reaches the eye so existing cones receive a clearer, less ambiguous signal.

After wearing the lenses for 90–120 seconds, the eyes naturally adjust through a process called chromatic adaptation — white appears as white again, while the enhanced color contrast is maintained.

What this means in practice:

  • Colors appear more vibrant, more distinct, and more saturated
  • Red-green confusion is reduced — many patients can distinguish colors they previously could not
  • Passing standardised color vision tests (Ishihara, Farnsworth D-15) becomes possible for some patients with prescribed, customised lenses
  • The glasses do not give a colorblind person normal color vision — but they can help some colors look more vibrant or noticeable, and significantly improve daily color discrimination Eye Institute
  • The effect is only present while wearing the lenses — vision returns to its baseline state when removed

Types of Color Blind Lenses Available in Bangladesh

There are two main formats — each with different advantages:

Spectacle Lenses (Glasses)
Tinted filter lenses mounted in spectacle frames. Available in indoor and outdoor versions — outdoor lenses are darker, tuned for bright sunlight where red-green contrast improvement is most noticeable. The most accessible format and suitable for patients of all ages including children.

Contact Lenses for Color Blindness
Some companies make contact lenses with a red filter, worn in one eye, to better distinguish between colors as needed. Customised color corrective contact lenses — prescribed after a detailed color vision evaluation — offer a more discreet option for patients who prefer not to wear spectacles. They are generally not visible to others and can be worn by anyone who has previously worn contact lenses.

The key distinction between generic off-the-shelf lenses and prescription color corrective lenses is critical. Generic lenses apply the same filter to all wearers regardless of their specific type or degree of deficiency. Customised lenses are prescribed after a full color vision examination — matched precisely to your deficiency type, severity, and the specific wavelength adjustment needed for your individual cone sensitivity profile.

“In my practice, when patients ask about color blind lenses, the most important thing I tell them is this: a generic filter from the internet and a properly prescribed, customised color vision lens are not the same thing. One is a product. The other is a medical solution. Get assessed properly, and you will know which option genuinely helps your specific type of color vision deficiency.”
— Dr. Ashraful Huq

Who Does a Color Blind Lens Actually Help?

Approximately 80% of people with red-green color blindness will see an expanded range of visible colors and distinguish shades more accurately when using appropriately prescribed color filter lenses. However, results vary significantly by:

Most likely to benefit:

  • Patients with deuteranomaly or protanomaly — the anomalous trichromats (reduced but not absent cone function). These patients have all three cone types but with shifted sensitivity, making them the ideal candidates for wavelength filtering
  • Patients who need to pass standardised color vision tests — Ishihara colour plates, Farnsworth D-15, Rabin Cone Contrast Test — for professional licensing (pilots, military, police, electrical workers, medical professionals)
  • Patients experiencing practical daily difficulties — choosing clothing colours, distinguishing traffic lights in certain conditions, reading colour-coded maps or graphs, distinguishing ripe from unripe fruit

Less likely to benefit:

  • Patients with deuteranopia or protanopia — the dichromats, who lack an entire cone type rather than having a shifted one. Filtering helps less when a cone type is entirely absent
  • Patients with tritanopia (blue-yellow deficiency) — most colour blind lenses are specifically designed for red-green deficiency
  • Patients with achromatopsia — complete absence of cone function; lenses cannot create cone sensitivity that does not exist
  • Patients seeking permanent correction — the effect ceases when the lenses are removed

Color Blindness and Career Impact in Bangladesh — Why This Matters

This is a dimension of color vision deficiency that rarely gets discussed in medical articles — but it matters enormously to my patients in Bangladesh.

Many professions in Bangladesh require passing a formal color vision test as a condition of employment or licensing. These include:

  • Bangladesh Navy, Army, and Air Force — color vision standards strictly enforced for active duty roles
  • Civil Aviation — pilots and air traffic controllers require full color vision or correctable CVD
  • Bangladesh Police Service — color vision testing at recruitment
  • Electrical and electronics engineering — wire colour identification is safety-critical
  • Medical and nursing professions — certain specialties require colour discrimination
  • Railway and transport — signal colour identification is essential
  • Graphic design and printing industries — colour accuracy is a core professional requirement

For patients in these categories, the goal is not just seeing more colors — it is passing the Ishihara or Farnsworth D-15 test that stands between them and their career. Customised prescriptive color corrective contact lenses, properly assessed and fitted, can make this possible for many patients with anomalous trichromacy.

I have seen patients in my clinic who had been turned away from their chosen career because of CVD — not knowing that a proper assessment and customised lens could have changed that outcome. This is why I believe awareness of color blind lens options in Bangladesh is so important.

What the Assessment Involves — Getting a Proper Color Vision Evaluation

A thorough color vision assessment at a specialist eye clinic involves several components:

1. History Taking
Understanding when the color vision difficulty was first noticed, whether it is congenital (present since birth) or acquired (developed over time), family history of CVD, and the specific situations where color confusion causes difficulty.

2. Ishihara Colour Plate Test
The most widely used screening test — a series of plates with numbers or patterns embedded in coloured dots. Identifies red-green deficiency quickly. Not suitable for precisely grading severity or type.

3. Farnsworth D-15 Panel Test
Fifteen coloured discs that must be arranged in colour order. Identifies the axis and severity of colour deficiency more precisely than Ishihara.

4. Rabin Cone Contrast Test (RCCT)
A more sensitive, computerised test that quantifies the specific degree of red, green, and blue cone sensitivity. Particularly relevant for professional color vision testing.

5. Anomaloscopy
The gold standard for precisely classifying the type and severity of red-green deficiency — distinguishing anomalous trichromacy from dichromacy with precision. Guides the exact wavelength filter prescription.

6. Full Eye Examination
It is important to rule out acquired causes of color vision change — cataracts, macular disease, glaucoma, optic neuritis, or medication side effects — particularly in adults whose color vision has changed over time. Color vision changes that come on later in life can point to eye disease, cataracts, neurologic problems, or medication side effects, and those need a clinical workup rather than a tinted lens.

Can Color Blindness Be Permanently Cured?

I want to answer this directly, because patients often come to me having read about gene therapy and hope it may be available in Bangladesh now.

To date, there is no therapeutic solution that can restore typical color vision. There have been considerable developments concerning technological interventions — hardware-based aids including tinted glasses and filters, and software-based methods for enhancing colour perception in digital environments.

Gene therapy for color blindness has shown promising early results in animal studies — and limited human trials have begun in the US for certain rare forms of achromatopsia. However, as of 2026, gene therapy for common red-green color blindness is not clinically available anywhere in the world, including Bangladesh. It remains a research-stage intervention.

What is available and proven:

  • Color blind spectacle and contact lenses — practical, accessible, beneficial for the majority of red-green CVD patients
  • Digital tools and apps — smartphone apps that identify and name colors, colorblind-friendly screen modes built into modern devices
  • Environmental adaptation strategies — labelling systems, colour-coded organisation tools

What is not yet available:

  • A permanent medical cure for inherited color vision deficiency
  • Gene therapy outside of clinical trial settings
  • Any eye drop, supplement, or exercise that restores cone function

 

Dr. Ashraful Huq’s Clinical Perspective

This blog was reviewed by Eye Specialist Dr. Ashraful Huq.

“Color vision deficiency is one of those conditions where I find patients have often carried unnecessary shame or limitation for years — simply because they did not know what options existed or were given no guidance beyond “there is nothing that can be done.”

That answer was never entirely true — and it is even less true today.

For the majority of my patients with red-green color blindness — the anomalous trichromats — a properly prescribed color corrective lens genuinely changes their daily experience. Not to normal color vision, but meaningfully closer to it. The patient who could not tell red from green on a traffic light in low light. The young engineer who failed his color vision test at recruitment and thought his career was over. The student who struggled with colour-coded biology diagrams. These are real problems with real, available solutions.

My honest advice: come for an assessment. Find out exactly what type and severity of color vision deficiency you have. Find out whether you are the type of patient who will benefit from color corrective lenses. Find out whether your specific situation — whether career-related or quality-of-life related — can be improved. You cannot make that decision without proper clinical information. And that information is available in Bangladesh, right now.”

Frequently Asked Questions — Color Blind Lens Bangladesh

Can color blindness be corrected in Bangladesh?

Color blindness cannot be permanently cured, but color blind lenses — specially filtered spectacle or contact lenses — can significantly improve colour discrimination for most patients with red-green colour vision deficiency. Customised prescription colour corrective lenses are available at specialist eye clinics in Bangladesh.

What is a color blind lens?

A color blind lens is a specially filtered optical lens — in spectacle or contact lens form — that blocks specific wavelengths of light where red and green cone sensitivities overlap. This increases contrast between red and green signals reaching the eye, helping the brain distinguish colours that previously appeared identical or similar.

Who benefits most from color blind lenses?

Patients with anomalous trichromacy — deuteranomaly or protanomaly — benefit most, as they have all three cone types but with shifted sensitivity. Patients needing to pass professional colour vision tests (Ishihara, Farnsworth D-15) for careers in aviation, military, medicine, or engineering are strong candidates for customised colour corrective lenses.

Do color blind lenses work permanently?

No. Colour blind lenses improve colour perception only while being worn. When the lenses are removed, vision returns to its baseline state. There is currently no permanent cure for inherited colour vision deficiency available anywhere in the world.

Can children use color blind lenses?

Yes. Colour blind lenses are safe for children from school age onwards. Early diagnosis and lens fitting can significantly improve a child’s educational experience — particularly with colour-coded learning materials — and avoid career limitation later. A full colour vision assessment at a specialist clinic is recommended.

How do I get a color blind lens in Bangladesh?

Visit a specialist ophthalmologist or optometrist for a full colour vision evaluation — including Ishihara plate testing, Farnsworth D-15 panel test, and ideally anomaloscopy for precise deficiency grading. Based on your type and severity, a customised colour corrective lens can be prescribed. Dr. Ashraful Huq performs full colour vision assessments at Bangladesh Eye Hospital (BEH), Dhaka.

Can color blind lenses help me pass the Ishihara test?

Customised prescription colour corrective contact lenses — properly assessed and fitted for your specific deficiency — can enable many patients with anomalous trichromacy to pass standardised colour vision tests including the Ishihara, Farnsworth D-15, and Rabin Cone Contrast Test. Generic off-the-shelf lenses are less reliable for this purpose.

Cataract Surgery Cost in Bangladesh 2026: Everything You Need to Know

Every week in my consultation room at Bangladesh Eye Hospital, I hear the same question from patients and their families: “Doctor, how much will cataract surgery cost in Bangladesh?”

It is always the first question — and it should be. Cost is a real concern for patients in Bangladesh, and I believe every patient deserves a clear, honest answer rather than a vague number that means nothing without context.

So in this article, I am going to tell you exactly what cataract surgery costs in Bangladesh in 2026 — broken down by procedure type, lens option, and setting. I will also explain the factors that determine the final price, what is typically included in a package, and — most importantly — how to make the right decision for your eyes and your family’s budget.

I have performed over 5,000 cataract procedures across my career. What I tell you here is what I tell my own patients.

What I See Every Day — Why Cataract Surgery Cost Varies So Much

One of the most confusing things for patients is that cataract surgery costs in Bangladesh can range from almost nothing at a government camp to over ৳1,50,000 at a private hospital — and both can be described simply as “cataract surgery.” The reason for this enormous range is not dishonesty. It comes down to three things: the surgical technique used, the intraocular lens (IOL) implanted, and where the surgery is performed.

Let me explain each of these clearly.

Cataract Surgery Cost in Bangladesh — 2026 Price Breakdown

Here is an honest, current overview of what you can expect to pay across different settings and procedure types in Bangladesh:

Procedure Type Cost Per Eye What It Means
SICS (Manual technique) ৳14,000–৳25,000 Older method; larger incision; mainly in govt/charity settings
Phaco — Basic Monofocal IOL ৳30,000–৳60,000 Gold-standard technique; standard imported lens
Phaco — Premium Monofocal IOL ৳60,000–৳1,00,000 Higher-quality imported lens; sharper distance vision
Phaco — Toric IOL ৳80,000–৳1,30,000 Corrects astigmatism at the same time as cataract
Phaco — Multifocal / Trifocal IOL ৳1,00,000–৳1,80,000 Near + distance vision; reduces or eliminates glasses
Femtosecond Laser-Assisted (FLACS) ৳90,000–৳1,20,000+ Highest surgical precision; laser replaces certain manual steps

In my practice at BEH, most patients choose Phaco surgery — the internationally recognised gold standard — with a lens type matched to their lifestyle and budget. I will discuss the lens options in detail shortly, as this is the single biggest cost decision you will make.

The 7 Factors That Determine Your Final Cataract Surgery Cost in Bangladesh

In my experience, patients are often surprised to learn that the surgeon’s fee is not always the biggest variable. Here is what actually drives the cost of cataract surgery in Bangladesh:

1. The IOL (Intraocular Lens) You Choose
This is the number one cost factor — by far. A basic monofocal lens and a premium trifocal lens can differ by ৳80,000–৳1,00,000 per eye. I will explain the lens options in the next section so you can make an informed choice.

2. Surgical Technique — Phaco vs. SICS vs. FLACS
Phacoemulsification (Phaco) is the procedure I perform and the one I recommend. It uses ultrasound to remove the cloudy lens through a tiny 2–3 mm incision with no stitches and a recovery time of 24–48 hours. SICS is an older technique with a larger incision — lower cost but longer recovery. FLACS (Femtosecond Laser-Assisted Cataract Surgery) adds laser precision to certain steps of Phaco for complex cases.

3. Surgeon’s Qualifications and Experience
I will be direct: an experienced, fellowship-trained cataract surgeon will charge a higher fee than a general ophthalmologist performing occasional cataract cases. That fee difference is not arbitrary — it reflects years of subspecialty training, thousands of cases, and the ability to handle complications safely if they arise.

4. Hospital or Facility Standards
A leading eye hospital like BEH with modern operating theatres, advanced pre-operative diagnostic equipment (biometry, corneal topography, retinal OCT), and strict sterile protocols costs more than a smaller clinic. These standards directly impact the safety of your surgery.

5. One Eye or Both Eyes
Most of my patients have cataracts in both eyes, though I operate one eye at a time, typically 2–4 weeks apart. Some facilities offer a package discount for bilateral surgery — always ask.

6. Pre-Operative Tests
Before cataract surgery, I perform a complete assessment: biometry (to calculate the precise IOL power for your eye), corneal topography, retinal examination, intraocular pressure check, and in some cases B-scan ultrasound. These may be bundled into the package or charged separately — always confirm in advance.

7. Post-Operative Medications and Follow-Ups
After surgery, patients use antibiotic and steroid eye drops for 4–6 weeks. Follow-up visits at Day 1, Week 1, and Week 4 are essential. Confirm whether these are included in the quoted price.

The IOL Decision — My Advice to Every Patient

This is the conversation I have with every patient before surgery, and I believe it is the most important part of your decision.

Monofocal IOL — The Standard Choice
A monofocal lens gives you excellent clarity at one distance — I usually set this for distance vision (driving, watching TV, seeing across a room). Reading glasses will typically still be needed for close work. This is the most widely used lens in Bangladesh, the most affordable, and delivers outstanding results for the right patient. If your priority is clear distance vision and you are comfortable using reading glasses, this is a perfectly sensible choice.

Toric IOL — For Patients with Astigmatism
If you have significant corneal astigmatism alongside your cataract, a standard monofocal lens will leave you needing glasses even for distance vision after surgery. A Toric IOL corrects the astigmatism at the same time as the cataract — in a single procedure. I recommend this for any patient with significant astigmatism who wants to minimise dependence on glasses post-surgery.

Multifocal / Trifocal IOL — For Glasses-Free Living
These premium lenses are the closest thing to having your young eyes back. They provide clear vision at near (reading), intermediate (computer, phone), and distance — all without glasses. Many of my patients with trifocal lenses can read the Quran, use their phone, and drive without reaching for glasses at any point. They cost significantly more than monofocal lenses — but for the right patient, the freedom they provide is transformative.

My honest recommendation: The “best” IOL is the one that best fits your life — not the most expensive one. I always ask my patients: how important is it to you to be glasses-free? What is your occupation? Do you read a lot? Do you drive at night? The answers guide the right choice. I never recommend a premium lens unless I am confident it will genuinely improve your quality of life.

Government vs. Private — An Honest Comparison

I want to address this directly, because I know many patients consider government hospitals for cost reasons.

Setting Typical Cost What to Expect
Government hospitals (NNBCP, district hospitals) Free or ৳1,000–৳5,000 Basic lens only; long waiting lists; limited diagnostic equipment
NGO / charity programmes (BNSB, Sightsavers) ৳3,000–৳15,000 Subsidised; basic monofocal lens; limited slots
Mid-tier private clinics, Dhaka ৳25,000–৳60,000 Standard Phaco; basic–mid range IOLs
Leading private eye hospitals, Dhaka ৳50,000–৳1,80,000 Full IOL range; advanced pre-op diagnostics; fellowship-trained surgeons

Government and NGO cataract programmes do an important, lifesaving job — particularly in rural Bangladesh where access to any eye care is limited. For a patient who simply needs a clear lens and accepts reading glasses for near work, a well-run government programme is a valid choice.

However, if you have significant astigmatism, a dense or complex cataract, a history of eye disease, or want a premium lens — a specialist private facility with advanced pre-operative assessment and fellowship-trained surgical care is the appropriate choice. The diagnostic equipment, surgical expertise, and aftercare at leading Dhaka eye hospitals is simply not comparable to government settings.

What is Included in My Cataract Surgery Package at BEH?

When patients come to me at Bangladesh Eye Hospital, I always provide a fully transparent, all-inclusive cost before any commitment is made. Here is what is included:

  • Comprehensive pre-operative assessment (biometry, corneal topography, retinal examination, IOP)
  • Phacoemulsification surgical procedure
  • The intraocular lens of your choice (discussed and agreed at consultation)
  • Operating theatre and equipment fees
  • Post-operative antibiotic and steroid eye drops (first supply)
  • Follow-up consultations at Day 1, Week 1, and Week 4
  • Direct access to my team if any concerns arise between appointments

There are no hidden charges. I tell patients exactly what they will pay — for the pre-op assessment, the surgery, and the aftercare — before they agree to anything.

Is Cataract Surgery Worth the Cost? My Honest View

I have operated on patients in their 50s, 60s, 70s, and 80s. I have operated on teachers who could not read the board, drivers who had stopped working because their vision was too poor, grandparents who could not recognise their grandchildren’s faces. The change in these patients after surgery — often visible within 24 hours — is one of the most rewarding things in medicine.

Cataract surgery cost in Bangladesh is among the lowest in the world for equivalent quality. Compare: the same Phaco procedure with a similar IOL costs ৳5,00,000–৳8,00,000 in the UK and ৳3,00,000–৳5,00,000 in India. In Bangladesh at a leading private hospital, you receive internationally trained surgical care at a fraction of the cost.

There is one more thing I always tell patients who are hesitating because of cost: do not wait too long. A cataract that is caught early — when it is soft and immature — is technically easier to remove, takes less ultrasound energy, carries a lower complication risk, and typically gives a faster recovery. A dense, mature, or hypermature cataract is a more demanding procedure. Early intervention is both safer and more cost-effective in the long run.

 

Dr. Ashraful Huq’s Clinical Perspective — A Word From Me Directly

This blog was reviewed by Eye Specialist Dr. Ashraful Huq.

“I want to add something personal here — something that goes beyond the price table.

In fifteen years of cataract surgery, the patients I worry most about are not the ones with complex cataracts or difficult eyes. They are the ones who waited too long because they were afraid of the cost, or because someone told them “just wait until it gets worse.” By the time some of these patients reach me, the cataract is so advanced that the surgery is significantly more difficult, the risk of complications is higher, and the visual recovery takes longer.

If you or a family member has been told they have a cataract — even an early one — please do not dismiss it. Come for a consultation. Find out exactly what you are dealing with, what the options are, and what it will cost. In my experience, most patients are surprised to find that the surgery is more straightforward, more affordable, and more life-changing than they feared.

Clear vision is not a luxury. It is the foundation of independence, safety, and quality of life. It is what allows an elderly parent to move around safely, a professional to continue working, a student to study. The cost of cataract surgery is real — and I take it seriously in every patient I see. But the cost of not treating it is always higher.”

Frequently Asked Questions

How much does cataract surgery cost in Bangladesh in 2026?

Cataract surgery cost in Bangladesh ranges from ৳30,000 for standard Phaco with a basic monofocal IOL to ৳1,80,000 or more for premium multifocal or trifocal lenses at leading private hospitals in Dhaka. The biggest cost variable is the type of intraocular lens chosen, not the surgical fee.

What is the difference between Phaco and SICS cataract surgery in Bangladesh?

Phacoemulsification (Phaco) is the gold-standard minimally invasive technique — a 2–3 mm incision, ultrasound lens removal, no stitches, 24–48-hour recovery. SICS is an older manual technique with a larger incision, lower cost, but longer recovery. I perform Phaco surgery exclusively as it delivers safer, faster, and better visual outcomes.

Is cataract surgery free in Bangladesh?

Government hospitals and NGO eye programmes offer cataract surgery at very low or no cost for eligible patients. However, lens options are limited to basic monofocal lenses and waiting lists can be long. Private facilities offer the full IOL range, advanced pre-operative diagnostics, and shorter waiting times.

Can I get glasses-free vision after cataract surgery?

Yes — with a premium multifocal or trifocal IOL. These lenses provide near, intermediate, and distance vision without glasses. They cost more than standard monofocal lenses but significantly reduce dependence on spectacles post-surgery. Suitability is confirmed at pre-operative assessment.

When is the right time to have cataract surgery?

The right time is when the cataract begins affecting your daily life — reading, driving, recognising faces, or working. You do not need to wait until vision is severely impaired. Earlier surgery is technically easier, carries lower risk, and gives faster recovery than operating on a dense, mature cataract.

What is the best hospital for cataract surgery in Bangladesh?

Bangladesh Eye Hospital (BEH) in Dhanmondi and Zigatola, Dhaka, is one of the country’s leading ophthalmic institutions. I perform cataract surgery at BEH using the latest Phacoemulsification technology and the full range of IOL options — from standard monofocal to premium trifocal lenses.

Does the quoted price include the IOL?

Always ask this question before committing to any facility. In my practice at BEH, the IOL is always included in the all-inclusive package price — there are no hidden charges. The IOL type and its cost is discussed and agreed with you before surgery.

LASIK vs SMILE vs ICL: Which Eye Surgery Is Right for You? (Bangladesh 2026)

LASIK vs SMILE vs ICL are the three most popular vision correction surgeries available today, especially for patients seeking freedom from glasses and contact lenses. Choosing the right procedure depends on your eye condition, corneal thickness, lifestyle, and long-term visual goals.

If you’re tired of glasses or contact lenses, modern vision correction surgery can provide long-term freedom and clearer vision. The three most popular options available in Bangladesh today are LASIK, SMILE, and ICL.

While all three procedures can effectively correct refractive errors, they are designed for different eye conditions and lifestyles. Understanding the differences can help you make an informed decision before your consultation.

LASIK: The Most Established Option

LASIK is one of the most widely performed eye surgeries worldwide. During the procedure, a thin flap is created in the cornea, and a laser reshapes the underlying tissue to correct vision.

Best For:

  • Mild to moderate myopia (short-sightedness)
  • Hyperopia (long-sightedness)
  • Astigmatism
  • Patients with healthy corneas

Advantages:

  • Fast procedure
  • Quick visual recovery
  • Proven long-term safety record
  • Generally the most affordable option

Considerations:

  • Involves creating a corneal flap
  • Higher risk of temporary dry eye compared to SMILE
  • Not suitable for every patient with thin corneas

SMILE: The Minimally Invasive Laser Procedure

SMILE (Small Incision Lenticule Extraction) is a newer laser vision correction technique that removes a tiny disc of tissue through a very small incision, without creating a flap.

Best For:

  • Myopia up to approximately -10D
  • Patients with active lifestyles
  • Athletes and contact sports participants
  • Individuals concerned about dry eye symptoms

Advantages:

  • Flap-free procedure
  • Smaller incision
  • Lower risk of dry eye
  • Better preservation of corneal strength

Considerations:

  • Does not treat hyperopia
  • May cost more than LASIK
  • Not every prescription is suitable

ICL: The Premium Option for High Prescriptions

ICL (Implantable Collamer Lens) involves placing a specialized lens inside the eye without removing corneal tissue. Unlike LASIK and SMILE, the cornea remains untouched.

Best For:

  • High myopia
  • Thin corneas
  • Patients unsuitable for laser surgery
  • Individuals seeking reversible vision correction

Advantages:

  • Excellent visual quality
  • No corneal tissue removal
  • Reversible if required
  • Outstanding results for high prescriptions

Considerations:

  • Higher cost
  • Involves lens implantation inside the eye
  • Requires specialized surgical expertise

LASIK vs SMILE vs ICL: Quick Comparison

Feature LASIK SMILE ICL
Flap Required Yes No No
Corneal Tissue Removal Yes Yes No
Suitable for High Myopia Limited Good Excellent
Dry Eye Risk Moderate Lower Lowest
Reversible No No Yes
Hyperopia Treatment Yes No Limited
Recovery Speed Fast Fast Fast

Which Procedure Is Right for You?

The best procedure depends on:

  • Your prescription
  • Corneal thickness
  • Dry eye status
  • Lifestyle and occupation
  • Long-term visual goals

In general:

  • LASIK is ideal for many patients seeking a proven and cost-effective solution.
  • SMILE is often preferred for active individuals who want a flap-free procedure.
  • ICL is frequently the best choice for patients with high prescriptions or thin corneas.

Cost Overview in Bangladesh (2026)

Approximate market ranges:

  • LASIK: ৳50,000–৳180,000
  • SMILE: ৳120,000–৳200,000
  • ICL: ৳150,000–৳280,000+

Actual costs vary depending on technology, surgeon expertise, and the complexity of the case.

 

Specialist’s Opinion

This blog was reviewed by Eye Specialist Dr. Ashraful Huq.

“There is no single ‘best’ vision correction procedure for every patient. The ideal treatment depends on your prescription, corneal health, lifestyle, and long-term visual goals. A detailed eye examination is essential to determine whether LASIK, SMILE, or ICL is the safest and most effective option for you.”


Dr. Ashraful HuqConsultant Ophthalmologist & Refractive Surgeon15+ Years of Experience | 5,000+ Successful Eye ProceduresSpecialist in LASIK, SMILE, ICL, Cataract & Advanced Vision Correction

LASIK, SMILE, and ICL are all highly effective and safe vision correction procedures, but each is designed for different eye conditions and patient needs. LASIK remains a trusted and widely used option for many patients; SMILE offers a flap-free and minimally invasive alternative, while ICL provides excellent results for high prescriptions and thin corneas where laser surgery may not be suitable.

Ultimately, the best procedure is not the most popular one, but the one that matches your eye health, prescription, lifestyle, and long-term visual goals. A proper diagnostic evaluation by an experienced refractive surgeon is the key step before making any decision.

As emphasized by Dr. Ashraful Huq, there is no universal “best” option—only the safest and most suitable choice for each individual after a detailed eye examination.

If you are considering vision correction surgery, consult a qualified eye specialist to determine which option—LASIK, SMILE, or ICL—can provide the safest path to clear, glasses-free vision.

Finding the Best LASIK Surgeon in Bangladesh

Every week, patients come to my clinic having already made their minds up about LASIK — based on a friend’s recommendation, an advertisement, or a price they found online. Some of them have chosen well; some have not, while finding the best LASIK Surgeon in Bangladesh.

Choosing the right LASIK surgeon is the single most important decision in the entire LASIK process. The laser does not perform the surgery — the surgeon does. And the surgeon’s experience, judgment, and honesty in assessing your suitability determines not just whether your outcome is good, but whether the procedure should have been recommended for you at all.

I have performed thousands of LASIK procedures in Bangladesh over fifteen years. In this guide, I will tell you exactly what to look for — and what to avoid — when choosing a LASIK surgeon.

What is LASIK Surgery?

LASIK (Laser-Assisted In Situ Keratomileusis) is a refractive laser eye surgery that permanently corrects myopia (short-sightedness), hyperopia (long-sightedness), and astigmatism by reshaping the cornea — the clear front surface of the eye — so that light focuses precisely on the retina.

At my practice, I perform Femto-LASIK — the most advanced, bladeless form of LASIK — using a femtosecond laser to create the corneal flap with sub-micron precision, rather than the mechanical blade used in older LASIK techniques. This significantly reduces flap-related complications and delivers more consistent outcomes.

I also perform SMILE (Small Incision Lenticule Extraction — flapless laser correction), PRK / Streamlight PRK (surface laser treatment), PTK with PRK (for corneal surface irregularities), and ICL (Implantable Collamer Lens — for patients not suitable for laser surgery). The right procedure depends on your eye — not what is most popular or most profitable.

Why the Surgeon Matters More Than the Technology

Every clinic in Bangladesh with a laser machine offers LASIK. The lasers are similar. What is not similar is the surgeon’s ability to:

  • Correctly identify patients who should not have LASIK — thin corneas, keratoconus risk, dry eye — and offer safer alternatives
  • Select the precise laser parameters for your individual corneal profile
  • Handle rare intraoperative complications calmly and correctly
  • Manage post-operative issues including dry eye, regression, or under-correction

A surgeon who only offers LASIK has a financial incentive to recommend LASIK for everyone. A surgeon who offers LASIK, SMILE, and ICL has the ability — and the professional obligation — to recommend what is actually right for your eyes.

Dr. Ashraful Huq’s Clinical Perspective

This blog was reviewed by Eye Specialist Dr. Ashraful Huq.

“The most important thing I do for any patient is the pre-operative assessment — not the surgery itself. Twenty minutes of careful examination determines whether the fifteen-minute procedure is safe and appropriate. Most complications I see in referred patients could have been prevented at that stage.”

7 Things to Look for When Choosing a LASIK Surgeon in Bangladesh

1. Fellowship Training in Refractive Surgery
A general ophthalmology degree alone is not sufficient for complex refractive surgery. Look for a surgeon with dedicated subspecialty fellowship training at a recognised refractive surgery centre. I completed my refractive surgery fellowship at LV Prasad Eye Institute, Hyderabad — one of Asia’s most respected centres for corneal and refractive surgery training.

2. Postgraduate Surgical Qualification
In Bangladesh, the relevant qualification is FCPS in Ophthalmology — the Fellow of the College of Physicians and Surgeons Bangladesh. This is the highest postgraduate surgical qualification available and involves rigorous examination and clinical assessment.

3. Track Record and Volume
An experienced LASIK surgeon in Bangladesh should have performed hundreds to thousands of procedures. Ask directly: how many LASIK procedures have you performed? How many complications have you encountered, and how did you manage them?

4. Offers Multiple Procedures — Not Just LASIK
If a surgeon only offers LASIK, they cannot offer you the most appropriate treatment. The best refractive surgeon assesses your eyes and recommends the safest, most suitable procedure — whether that is Femto-LASIK, SMILE, PRK, or ICL.

5. Thorough Pre-operative Assessment
A reputable LASIK surgeon will never schedule you for surgery at your first appointment without a full pre-operative assessment. This must include: corneal topography, pachymetry (corneal thickness), tear film assessment, pupil measurement, cycloplegic refraction, and dilated retinal examination. If a clinic skips any of these, walk away.

6. Transparent, Honest Communication
The surgeon should explain your results clearly, tell you if you are not a good candidate (and why), present all options honestly, and give you realistic expectations — including what can and cannot be guaranteed. Beware of any clinic that promises perfect results without caveats.

7. Recognised Awards and Peer Recognition
Awards from peer bodies — not patient review sites — indicate recognition by the surgical community. I was awarded the Best Paper Award at the 14th Biannual SAARC Academy of Ophthalmology, Kathmandu 2018, and the Asia Pacific Academy of Ophthalmology Best Young Ophthalmologist Award, 2021.

Red Flags — When to Walk Away

  • The clinic schedules your surgery without a full pre-operative assessment
  • You are told you are “definitely suitable” without corneal topography being performed
  • The surgeon cannot explain what happens if a complication occurs
  • Pricing is suspiciously low with unexplained package inclusions
  • The surgeon pressures you to decide immediately
  • No follow-up appointments are included in the quoted price

What to Ask at Your LASIK Consultation

Bring these questions to any LASIK consultation in Bangladesh:

  1. Am I genuinely a good candidate? Why or why not?
  2. Which procedure do you recommend for my eyes specifically — LASIK, SMILE, PRK, or ICL?
  3. What is my corneal thickness, and how much tissue will the laser remove?
  4. What is your personal complication rate, and how do you manage complications?
  5. What is included in the quoted price — pre-op assessment, surgery, drops, follow-ups?
  6. What results should I realistically expect based on my prescription and corneal measurements?

A surgeon who answers these questions clearly and without irritation is the right surgeon.

Preparing for Your LASIK Surgery — What to Do Before

Once you have chosen your surgeon and confirmed your suitability, here is how to prepare:

  • Confirm the date and time of your surgery directly with the clinic
  • Stop wearing soft contact lenses at least 3 days before your assessment; rigid/gas-permeable lenses at least 2 weeks before
  • Use antibiotic eye drops the day before surgery as prescribed
  • Perform lid hygiene with baby shampoo as instructed by Dr. Huq
  • Arrange transport home — you cannot drive after LASIK
  • Do not wear eye makeup or perfume on the day of surgery
  • Read and sign the consent form — if you have any questions, raise them before signing
  • Contact the clinic if you have any concerns before the procedure

What Happens on the Day of LASIK Surgery

Femto-LASIK at BEH with Dr. Ashraful Huq is a day-case procedure — you arrive, have the surgery, and return home the same day. Here is what to expect:

Anaesthetic eye drops are instilled to numb the eye completely. The femtosecond laser creates a precise, thin corneal flap — taking approximately 30–45 seconds. The flap is lifted, the excimer laser reshapes the cornea to your exact prescription in 30–90 seconds, and the flap is repositioned. The incision self-seals without stitches. Most patients notice improved vision before they even sit up.

Total laser time: under 2 minutes per eye. Total clinic time: approximately 2–3 hours including preparation and post-operative monitoring.

LASIK is not painful. Anaesthetic drops numb the eye completely. Some patients feel mild pressure during flap creation — not pain. Post-operatively, mild burning and light sensitivity are normal for 6–12 hours and resolve with rest.

Recovery — What to Expect

Most patients achieve functional vision within 24 hours. Full stabilisation occurs over 4–6 weeks.

  • Day 1: Vision dramatically improved. First post-operative review with Dr. Huq.
  • Days 2–7: Rapid improvement. Antibiotic and steroid drops used strictly as prescribed.
  • Week 2: Most daily activities, screen use, and light work fully resumed.
  • Week 3–4: Driving cleared in most cases after formal confirmation from Dr. Huq.

Do not rub your eyes for at least 1 month. Do not swim for 2 weeks. Do not wear eye makeup for 1 week. Do not miss follow-up appointments.

Can LASIK correct all vision problems?
LASIK corrects myopia (up to –12 D), hyperopia (up to +6 D), and astigmatism (up to ±6 D) in suitable candidates. It is not appropriate for all patients — thin corneas, keratoconus, significant dry eye, or very high prescriptions may require SMILE, PRK, or ICL instead.

Is LASIK covered by insurance in Bangladesh?
LASIK is generally considered an elective procedure and is not covered by most Bangladeshi health insurance plans. Dr. Huq’s team provides a transparent, all-inclusive quote at consultation.

What is the age requirement for LASIK in Bangladesh?
The minimum recommended age is 18, with 21 preferred once the prescription has been stable for at least 12 months. There is no strict upper age limit — suitability is assessed individually.

What is the cost of LASIK surgery in Bangladesh?
Femto-LASIK costs approximately ৳60,000–৳1,20,000 per eye at leading private facilities in Dhaka, depending on prescription complexity and facility. Dr. Huq’s team provides a fully transparent breakdown at your pre-operative consultation.

ICO Glaucoma Guidelines for diagnosis and treatment in Bangladesh — Dr. Ashraful Huq, Ophthalmologist Dhaka
Posted on Author Dr Ashraful Huq

ICO Glaucoma Guidelines: Diagnosis, Treatment & Care in Bangladesh

Glaucoma is one of the leading causes of irreversible blindness worldwide — and in Bangladesh, it remains significantly underdiagnosed. The International Council of Ophthalmology (ICO) Glaucoma Guidelines provide a globally recognized framework for diagnosing, managing, and treating glaucoma at every stage. As an ophthalmologist with specialized training in glaucoma services, Dr. Ashraful Huq follows these evidence-based protocols to deliver the best possible outcomes for patients in Dhaka.

Dr. Ashraful Huq’s Clinical Perspective

This blog was reviewed by Eye Specialist Dr. Ashraful Huq.

“Glaucoma is often called the ‘silent thief of sight’ — and in my clinical experience in Bangladesh, that description is painfully accurate. Many patients arrive at my clinic having already lost significant peripheral vision, simply because there were no warning signs to prompt them to seek care earlier.

The ICO guidelines exist precisely to give ophthalmologists a structured, evidence-based framework — so that whether a patient presents early or late, we are following the best available protocol for their stage of disease.

What I want patients in Bangladesh to understand is this: glaucoma is not a death sentence for your vision. Detected early and managed consistently, the vast majority of my patients keep functional sight for the rest of their lives. The problem is not a lack of treatment — it is a lack of awareness that leads people to present too late.

My advice is simple: if you are over 40, have a family history of glaucoma, or have high myopia, do not wait for symptoms. Come for a comprehensive eye examination. The test is painless, takes less than an hour, and the information it gives you is irreplaceable.”

What Is Glaucoma?

Glaucoma is a group of eye diseases that damage the optic nerve — the nerve that carries visual information from the eye to the brain. This damage is usually caused by abnormally high intraocular pressure (IOP). Left untreated, glaucoma causes progressive, permanent vision loss, starting with peripheral (side) vision and eventually leading to total blindness.

The most common types include:

  • Primary Open-Angle Glaucoma (POAG) — the most prevalent form; develops slowly and painlessly
  • Angle-Closure Glaucoma — can develop suddenly (acute) or gradually; more common in Asian populations
  • Normal-Tension Glaucoma — optic nerve damage occurs even with normal IOP
  • Secondary Glaucoma — caused by another eye condition, injury, or medication

Important: Most people with early glaucoma have no symptoms. Regular eye check-ups are the only way to detect it before significant vision loss occurs.

What Are the ICO Glaucoma Guidelines?

The ICO (International Council of Ophthalmology) publishes globally recognized clinical guidelines to standardize glaucoma care across different resource settings. The guidelines are stratified into three levels:

Resource Level Setting Focus
Basic Primary care / limited equipment Screening, referral, IOP control
Standard General ophthalmology Full diagnosis, medical & laser management
Advanced Subspecialty / surgical centers Complex cases, surgical intervention

Bangladesh Eye Hospital, where Dr. Ashraful Huq practices, operates at the Standard to Advanced level — meaning patients have access to comprehensive glaucoma diagnostics and treatment options.

ICO Guidelines: Key Diagnostic Criteria

According to ICO recommendations, glaucoma diagnosis requires a multi-parameter assessment — not just measuring eye pressure alone.

1. Intraocular Pressure (IOP) Measurement

  • Normal IOP: 10–21 mmHg
  • Elevated IOP (>21 mmHg) is a major risk factor but not the sole diagnostic criterion
  • Goldmann applanation tonometry is the gold standard

2. Optic Nerve Head (ONH) Evaluation

  • Fundus examination to assess cup-to-disc ratio (CDR)
  • CDR > 0.65 or asymmetry > 0.2 between eyes warrants further investigation
  • Disc hemorrhages are a significant risk marker

3. Visual Field Testing (Perimetry)

  • Automated perimetry (Humphrey or Octopus) to map peripheral and central vision loss
  • Repeated testing is required to confirm progressive field defects

4. Gonioscopy

  • Essential to classify glaucoma as open-angle or angle-closure
  • Determines whether laser iridotomy is needed

5. Pachymetry (Corneal Thickness)

  • Thin corneas can cause IOP to be underestimated
  • Central corneal thickness (CCT) adjusts IOP interpretation

ICO Guidelines: Treatment Framework

Medical Treatment (First Line)

The ICO recommends starting with the least invasive, most effective option:

  • Prostaglandin analogues (e.g., latanoprost, bimatoprost) — first-line for POAG; once-daily dosing
  • Beta-blockers (e.g., timolol) — effective but caution in asthma and cardiac patients
  • Alpha-2 agonists (e.g., brimonidine) — used as adjunctive therapy
  • Carbonic anhydrase inhibitors (e.g., dorzolamide) — topical or oral

Target IOP is individualized based on the stage of glaucoma and patient profile.

Laser Treatment

  • Selective Laser Trabeculoplasty (SLT) — first-line alternative to drops for POAG; repeatable
  • Laser Peripheral Iridotomy (LPI) — definitive treatment for angle-closure and prevention in narrow angles

Surgical Treatment

When medications and laser fail to control IOP adequately:

  • Trabeculectomy — gold standard filtering surgery; creates a new drainage pathway
  • Tube-shunt implants — for refractory or complex cases
  • Minimally Invasive Glaucoma Surgery (MIGS) — newer options with faster recovery

Glaucoma Risk Factors: Who Should Be Screened?

The ICO recommends glaucoma screening for individuals with any of the following:

  • Age over 40 years
  • Family history of glaucoma (first-degree relative)
  • High myopia (nearsightedness) — patients considering LASIK surgery or ICL surgery should be evaluated for glaucoma before surgery
  • Diabetes mellitus
  • History of ocular trauma or steroid use
  • Previous eye surgery
  • Thin central cornea

Patients with keratoconus or corneal disease also require careful monitoring, as corneal abnormalities can mask true IOP readings and complicate glaucoma assessment.

Glaucoma and Refractive Surgery: What You Must Know

Patients planning vision correction surgery need pre-operative glaucoma screening. Here is why:

Dr. Ashraful Huq performs a thorough glaucoma risk assessment for all surgical candidates as part of the pre-operative workup.

ICO Guidelines on Follow-Up and Monitoring

Glaucoma management is lifelong. The ICO recommends:

Stage Follow-Up Frequency
Glaucoma suspect / OHT Every 6–12 months
Early glaucoma, stable Every 6 months
Moderate glaucoma Every 3–6 months
Advanced or progressing Every 1–3 months

At each visit, IOP is measured, medication compliance is assessed, and visual fields are retested periodically (at least annually in stable patients).

Glaucoma Care in Bangladesh: What to Expect at Dr. Ashraful Huq’s Clinic

Dr. Ashraful Huq has specialist training in glaucoma services from Bangladesh Eye Hospital & Institute, Dhaka, and L V Prasad Eye Institute, Hyderabad — one of Asia’s premier eye institutions. His clinic offers:

  • Comprehensive IOP measurement and optic nerve assessment
  • Visual field testing and optic disc imaging
  • Gonioscopy for angle assessment
  • Medical management with all major glaucoma drop classes
  • Laser peripheral iridotomy
  • Referral for advanced surgical intervention where indicated

Frequently Asked Questions (FAQ)

Q: Can glaucoma be cured? No — glaucoma cannot be cured, but it can be controlled effectively. With proper treatment, most patients retain functional vision for life.

Q: Is glaucoma always painful? No. The most common form (primary open-angle glaucoma) is entirely painless. Acute angle-closure glaucoma can cause sudden severe eye pain, headache, and nausea — this is a medical emergency requiring immediate treatment.

Q: Can I have glaucoma even if my eye pressure is normal? Yes. Normal-tension glaucoma is a recognized condition where optic nerve damage occurs at IOP within the normal range. A full eye examination — not just pressure checking — is essential.

Q: Does glaucoma run in families? Yes. Having a first-degree relative with glaucoma increases your risk by 4–9 times. Screening of family members is strongly recommended.

Q: Can high myopia increase glaucoma risk? Yes. People with high myopia have a structurally larger and more vulnerable optic nerve, which increases susceptibility. If you are myopic and considering LASIK or ICL surgery, glaucoma screening is part of the pre-surgical evaluation.

WHO Guidelines for Management of Corneal Ulcers — What Every Patient Should Know

A corneal ulcer is one of the most serious eye emergencies I encounter in clinical practice. In my years at Bangladesh Eye Hospital, I have seen patients arrive with corneas that were near-perforation — not because their condition was untreatable, but because they did not know the warning signs, did not seek care quickly enough, or received incorrect initial treatment at the primary level.

The World Health Organization (WHO) published guidelines specifically for the South-East Asia region on the management of corneal ulcers across primary, secondary, and tertiary care facilities. As a cornea-trained ophthalmologist who completed my fellowship at LV Prasad Eye Institute — one of Asia’s leading corneal centres — I want to translate these guidelines into clear, practical information that patients and healthcare workers in Bangladesh can actually use.

This article covers what a corneal ulcer is, why it is an emergency, how it should be managed at each level of care, and when urgent referral to a cornea specialist is essential.

What is a Corneal Ulcer?

The cornea is the clear, dome-shaped front surface of the eye — the transparent window through which light enters. It plays a critical role in focusing vision and acts as the eye’s primary physical barrier against infection and injury.

A corneal ulcer is an open wound or erosion of the corneal tissue, typically caused by infection. It is not a superficial scratch. A corneal ulcer penetrates into the layers of the cornea itself — and if left untreated or poorly treated, it can destroy the cornea, cause perforation of the eye, and result in permanent vision loss or loss of the eye entirely.

Infectious keratitis, often manifesting as a corneal ulcer, is a significant cause of ocular morbidity worldwide — ranking among the top five causes of blindness globally, and disproportionately impacting marginalized groups. Dr. Agarwals

In Bangladesh, corneal ulcers are particularly common due to agricultural work (plant matter and soil are major risk factors for fungal keratitis), widespread use of traditional eye remedies that delay medical care, and limited access to specialist ophthalmology outside Dhaka and major cities.

What Causes Corneal Ulcers?

Understanding the cause is essential — because the treatment differs significantly depending on the causative organism.

Bacterial Keratitis — Most Common
The most frequent cause in Bangladesh, particularly following eye injuries from plant material, dust, or contaminated water. Bacterial keratitis is the most common cause of infectious corneal ulcers and should be the top differential diagnosis in patients presenting acutely with corneal infiltrates. It is often rapid in onset and progression, with potential for corneal melting and perforation within days. Dr. Agarwals

Common organisms include Pseudomonas aeruginosa (particularly aggressive — can destroy the entire cornea within days), Staphylococcus aureus, and Streptococcus pneumoniae.

Fungal Keratitis
In Bangladesh, fungal keratitis is the second most common cause — and arguably more difficult to treat. It typically follows trauma with vegetable matter: a paddy stalk, tree branch, or soil particle. Fungal ulcers tend to have feathery borders, satellite lesions, and a dry-looking surface — quite different from bacterial ulcers. They do not respond to antibiotics and require specific antifungal treatment, which many primary-level facilities do not stock.

Viral Keratitis — Herpes Simplex
Herpes simplex virus (HSV) is a significant cause of recurrent corneal ulceration, particularly the classic dendritic (branching) ulcer visible on fluorescein staining. It requires antiviral treatment — not antibiotics — and misdiagnosis with inappropriate steroid use can be catastrophic, causing rapid corneal destruction.

Acanthamoeba Keratitis
Less common but devastating. Associated with contact lens use, particularly in users who swim with lenses in or use tap water for lens cleaning. Acanthamoeba keratitis is extremely painful — often disproportionate to clinical signs — and resistant to most standard treatments. It requires prolonged specific therapy and is frequently misdiagnosed.

Risk Factors in Bangladesh

  • Agricultural work — plant matter injuries are the single biggest risk factor for fungal keratitis
  • Contact lens use — particularly poor hygiene or tap water use
  • Traditional eye remedies — a major cause of delayed presentation and worsened outcomes
  • Diabetes — impairs corneal healing and immune response
  • Previous eye surgery or chronic eye disease
  • Malnutrition and Vitamin A deficiency — particularly in children

Warning Signs — When to Seek Urgent Care

This is the most important section for patients and their families. A corneal ulcer is an ophthalmic emergency. If you or a family member has any of the following symptoms — especially after an eye injury — do not wait, do not apply home remedies, and do not use steroid eye drops without a doctor’s prescription.

The common symptoms of corneal ulceration include redness of the eye, circumcorneal congestion, pain, blurring of vision, photophobia (sensitivity to light), and watering of the eye — all with varying degrees of severity. Drashrafulhuq

Go to an eye specialist immediately if you have:

  • A white or grey spot on the cornea (the coloured part of the eye)
  • Sudden pain in the eye, especially after an injury
  • Significant sensitivity to light
  • Rapidly worsening vision
  • Discharge from the eye combined with corneal haziness
  • A red, painful eye that is not improving after 24–48 hours of antibiotic drops

“In my experience, the most preventable causes of permanent vision loss from corneal ulcers are delayed presentation and the use of traditional remedies or over-the-counter steroid drops before seeking specialist care. A corneal ulcer that is caught early and treated correctly has an excellent prognosis. The same ulcer treated late or incorrectly can end in a blind eye. Time matters enormously.”
— Dr. Ashraful Huq

WHO Guidelines — Management at Each Level of Care

The WHO Regional Office for South-East Asia published guidelines for the management of corneal ulcers at primary, secondary, and tertiary care health facilities specifically for the South-East Asia region — which includes Bangladesh. Here is how those guidelines translate into practice: Alcon

Primary Level — First Contact Care

At the primary level — a community clinic, health centre, or general practitioner — the most important role is rapid recognition and immediate referral. A suppurative corneal ulcer is an ophthalmic emergency which should be referred to the nearest eye centre for proper management. Drashrafulhuq

Before referral, the primary provider should:

  • Apply broad-spectrum antibiotic eye drops (e.g. ciprofloxacin 0.3% or moxifloxacin 0.5%) hourly
  • Instruct the patient to continue drops frequently during transit to the referral centre
  • Never apply steroid eye drops — this is absolutely contraindicated without specialist assessment
  • Never pad or patch the eye tightly — this creates a warm, moist environment that accelerates bacterial growth
  • Document the history of injury, contact lens use, and any prior treatment

What primary care should NOT do:

  • Prescribe steroid eye drops — can turn a treatable ulcer into a perforating one
  • Apply traditional eye remedies of any kind
  • Delay referral to see if the condition improves over several days
  • Prescribe oral antibiotics as the sole treatment for a corneal ulcer

Secondary Level — District Eye Hospital

At the secondary level, the ophthalmologist should perform a full slit-lamp examination and attempt to establish the causative organism through corneal scraping and microbiological culture where possible.

Current guidelines recommend immediate treatment with broad-spectrum topical antibiotics as the first-line approach, with emphasis on empiric therapy for small noncentral ulcers. For bacterial ulcers, fluoroquinolones such as moxifloxacin 0.5% or ciprofloxacin 0.3% should be administered every 15–30 minutes for the first few hours, then hourly while awake for 24–48 hours, followed by gradual tapering based on clinical response. American Academy of Ophthalmology

Key management principles at secondary level:

  • Corneal scraping for Gram stain, KOH preparation (for fungi), and culture sensitivity
  • Topical fluoroquinolone monotherapy as first-line for most bacterial ulcers
  • Fortified antibiotic drops (tobramycin + cefazolin) for severe cases
  • Natamycin 5% eye drops for suspected fungal keratitis — not fluoroquinolones
  • Acyclovir ointment for suspected HSV dendritic ulcers — not antibiotics
  • Cycloplegic drops (atropine) to reduce pain from ciliary spasm and prevent posterior synechiae
  • Corticosteroids may be considered after 48 hours of antibiotic therapy when the causative organism is identified and the infection has responded to therapy — but should be avoided in cases of suspected Acanthamoeba, Nocardia, or fungal infection. American Academy of Ophthalmology

Tertiary Level — Specialist Cornea Centre

At the tertiary level — a specialist cornea unit such as at Bangladesh Eye Hospital — management becomes more complex, particularly for cases that have not responded to initial treatment, have unusual organisms, or present with advanced corneal destruction.

At BEH, I manage cases referred from across Bangladesh, many of whom arrive after days or weeks of inadequate treatment elsewhere. Tertiary-level management may include:

  • Repeat corneal scraping with extended culture techniques including fungal and Acanthamoeba-specific media
  • Confocal microscopy for Acanthamoeba and fungal diagnosis without scraping
  • Intensive fortified antibiotic or antifungal regimens tailored to organism and sensitivity
  • Therapeutic penetrating keratoplasty (corneal transplant) for cases with impending or actual perforation
  • Tissue adhesive (cyanoacrylate glue) and bandage contact lens for small perforations
  • Long-term management of corneal scarring, including optical and tectonic keratoplasty

Corneal Scarring — What Happens After a Corneal Ulcer Heals?

This is something many patients are not told at the time of treatment — and it is important.

When a corneal ulcer heals, it leaves a scar. Unlike skin scars that can be hidden, a corneal scar sits directly in the visual axis — the path light travels to reach the retina. Depending on the size, depth, and location of the scar, this can cause:

  • Permanent reduction in vision
  • Irregular astigmatism — distorted, blurred vision that cannot be corrected by standard glasses
  • Complete opacity — a white scar that blocks light entirely (leucoma)

For patients with corneal scarring that significantly affects vision, options at the tertiary level include:

  • Rigid gas-permeable contact lenses — can mask irregular astigmatism in some patients
  • Deep anterior lamellar keratoplasty (DALK) — replaces the scarred corneal layers while preserving the patient’s own endothelium
  • Penetrating keratoplasty (PK) — full-thickness corneal transplant for severe cases
  • Keratoprosthesis — in rare cases where standard transplantation has failed

The Role of Prevention — What Every Patient Can Do

Most corneal ulcers in Bangladesh are preventable. The following measures reduce risk significantly:

For agricultural workers:

  • Wear protective eyewear when working with crops, particularly during harvesting
  • Wash eyes immediately with clean water after any eye injury — then seek care
  • Never rub soil or plant material into an injured eye
  • Seek eye care within 24 hours of any penetrating eye injury — do not wait

For contact lens wearers:

  • Never sleep in contact lenses
  • Never use tap water to clean or store lenses
  • Never swim with contact lenses in
  • Replace lenses and cases on schedule
  • Remove lenses immediately if the eye becomes red, painful, or uncomfortable

For everyone:

  • Never use steroid eye drops without a prescription from an ophthalmologist
  • Never apply traditional eye remedies — kohl, breast milk, plant extracts, or any substance not prescribed by a doctor
  • Seek urgent care for any red, painful eye that does not improve within 24 hours

Dr. Ashraful Huq’s Clinical Perspective

I want to add something that the guidelines do not capture — what I see in clinic week after week.

The single most damaging thing that happens to corneal ulcer patients in Bangladesh is not the initial infection. It is what happens between the injury and the point they reach me. It is the three days of antibiotic drops that were not given frequently enough. It is the steroid drop prescribed by a well-meaning general practitioner who thought it would reduce the redness. It is the traditional remedy applied by a family member before the patient could be brought to Dhaka. It is the delay caused by cost, distance, or the belief that “it will get better on its own.”

By the time I see these patients, what began as a treatable ulcer has become a surgical emergency. Corneas that could have healed with drops now need transplants. Eyes that could have had normal vision now have permanent scars.

The WHO guidelines exist because this pattern is well recognised across South-East Asia. The pathway is clear: rapid recognition at the primary level, immediate topical antibiotic treatment, no steroids, prompt referral upward. When that pathway works, outcomes are excellent. When it breaks down at any point — through delay, misdiagnosis, or inappropriate treatment — patients pay the price with their vision.

If you have an eye injury or a red, painful eye that is not improving — please do not wait. Come and be assessed. Early treatment is always better, always safer, and always cheaper than treating the consequences of delay.

Frequently Asked Questions

What is a corneal ulcer?
A corneal ulcer is an open wound or erosion in the cornea — the clear front surface of the eye — usually caused by bacterial, fungal, viral, or amoebic infection. It is an ophthalmic emergency. Without prompt and correct treatment, it can cause permanent vision loss or loss of the eye.

What are the symptoms of a corneal ulcer?
Key symptoms include a white or grey spot on the cornea, eye pain, redness, photophobia (light sensitivity), watering, and blurred vision — especially after an eye injury. If you have these symptoms, seek urgent eye care immediately and do not apply any drops or remedies without medical advice.

Can a corneal ulcer heal on its own?
No. A corneal ulcer requires prompt medical treatment with appropriate eye drops — antibiotic, antifungal, or antiviral depending on the cause. Leaving a corneal ulcer untreated allows it to deepen, spread, and potentially perforate the eye. Do not wait for it to resolve on its own.

Are steroid eye drops safe for corneal ulcers?
No — not without specialist assessment. Steroid eye drops applied to an active bacterial, fungal, or viral corneal ulcer can cause rapid worsening, deeper penetration of infection, and perforation. Never use steroid drops for a red or painful eye without a confirmed diagnosis from an ophthalmologist.

What is the treatment for a corneal ulcer in Bangladesh?
Treatment depends on the cause. Bacterial ulcers are treated with intensive topical fluoroquinolone antibiotics. Fungal ulcers require natamycin antifungal drops. Viral (HSV) ulcers need antiviral therapy. Severe cases may need corneal transplantation. At Bangladesh Eye Hospital, Dr. Ashraful Huq manages complex corneal ulcer cases from across the country.

Can vision be restored after a corneal ulcer?
It depends on the size, depth, and location of the resulting scar. Small, peripheral scars may not affect vision significantly. Central or dense scars can permanently reduce vision. For significant corneal scarring, options include rigid contact lenses or corneal transplantation (keratoplasty) — both available at BEH with Dr. Ashraful Huq.

Confronting Corneal Ulcers: Causes, Treatment & When to See a Specialist

Confronting Corneal Ulcers: Causes, Treatment & When to See a Specialist

In my years at Bangladesh Eye Hospital, few conditions concern me as much as a corneal ulcer that has been left untreated — or worse, treated incorrectly — before the patient reaches me.

A corneal ulcer is not a minor eye infection. It is an open wound on the most critical optical surface of the eye. Without the right treatment, started urgently, it can destroy the cornea within days and leave a patient permanently blind in that eye.

This article tells you what a corneal ulcer is, what causes it in Bangladesh specifically, how to recognise it early, and what the correct treatment pathway looks like — from a specialist who has managed these cases at both the secondary and tertiary level.

What is a Corneal Ulcer?

The cornea is the clear dome at the front of the eye through which you see. It has five layers, and its transparency is critical to sharp vision. A corneal ulcer — also called infectious keratitis — is a break in the corneal epithelium (the outermost layer) that extends into deeper layers, caused by microbial infection.

Unlike a superficial scratch, which heals in 24–72 hours, a corneal ulcer involves active infection eating into corneal tissue. If untreated, it progresses from the outer layers inward, can perforate the eye entirely, and allows infection to enter the interior of the eye — a condition called endophthalmitis, which can be blinding or require removal of the eye.

What Causes Corneal Ulcers?

Bacterial Keratitis

The most common cause in Bangladesh. Follows eye injury — even a minor scratch from a plant, fingernail, or piece of dust. The most aggressive organisms are Pseudomonas aeruginosa (can destroy the entire cornea in 48 hours) and Staphylococcus aureus. Onset is rapid — redness, pain, and a white spot developing within hours to days.

Fungal Keratitis

The second most common cause in Bangladesh — and the one I see most often in patients referred from rural areas. Typically follows trauma with vegetable matter: a paddy stalk, tree branch, or soil. Fungal ulcers are slower to develop, have characteristic feathery edges and satellite lesions, and do not respond to antibiotic eye drops. Natamycin antifungal drops are required — which many primary-level facilities do not stock.

Herpes Simplex Viral Keratitis

Caused by HSV-1 — the same virus as cold sores. Produces a classic dendritic (branching) ulcer visible on fluorescein staining. Requires antiviral treatment (acyclovir). The critical danger: if steroids are applied to an HSV ulcer — a common mistake — the infection spreads rapidly and causes geographic ulceration, potentially destroying the entire corneal surface.

Acanthamoeba Keratitis

Linked to contact lens use — particularly swimming with lenses, using tap water to clean lenses, or poor lens hygiene. Excruciatingly painful — often out of proportion to what is visible on examination. Resistant to most standard treatments and frequently misdiagnosed as HSV or bacterial keratitis. Requires specific prolonged therapy with polyhexamethylene biguanide (PHMB) drops.

Risk Factors Specific to Bangladesh

  • Agricultural work with plant material
  • Traditional eye remedies — the single most damaging factor I see in referred patients
  • Contact lens use with poor hygiene
  • Diabetes — impairs corneal healing and immune response
  • Vitamin A deficiency — particularly in malnourished children
  • Delayed presentation due to cost, distance, or minimisation of symptoms

Warning Signs — Seek Urgent Eye Care Immediately

Do not wait if you or a family member has:

  • A white or grey spot on the coloured part of the eye
  • Eye pain — especially after an injury or foreign body sensation
  • Rapid worsening of vision
  • Significant sensitivity to bright light
  • A red, watering eye that is not improving after 24 hours
  • Any eye injury involving plant material, soil, or a foreign body

“A corneal ulcer caught in the first 24–48 hours and treated correctly has an excellent prognosis. The same ulcer after three days of the wrong treatment — or traditional remedies — is a surgical emergency. Time is cornea.”
— Dr. Ashraful Huq

Never apply these before seeing a doctor:

  • Steroid eye drops — accelerates infection and can perforate the cornea
  • Traditional remedies — breast milk, plant extracts, kohl, any non-prescribed substance
  • Antibiotic drops alone for a fungal or viral ulcer — delays the right treatment

Diagnosis — What I Do at the First Visit

A thorough assessment is essential before any treatment is started. At BEH, my assessment includes:

  • Slit-lamp examination — detailed visualisation of the ulcer’s size, depth, location, and characteristics
  • Fluorescein staining — reveals the ulcer’s exact shape; a dendritic pattern indicates HSV
  • Corneal scraping — material from the ulcer base is sent for Gram stain, KOH preparation (for fungi), and culture sensitivity
  • Anterior segment OCT — assesses depth of stromal involvement without contact
  • Intraocular pressure — elevated IOP can complicate management
  • Full history — mechanism of injury, contact lens use, prior treatment, duration of symptoms, and — critically — whether any traditional remedies or steroid drops have been used

The culture result takes 48–72 hours, but treatment begins immediately based on clinical appearance while awaiting results.

Treatment — How Corneal Ulcers Are Managed

Bacterial Ulcer

Intensive topical fluoroquinolone antibiotics — moxifloxacin 0.5% or ciprofloxacin 0.3% — every 15–30 minutes for the first few hours, then hourly while awake. For severe or central ulcers: fortified antibiotic drops (tobramycin + cefazolin). Cycloplegic drops (atropine) reduce pain from ciliary spasm. Patching is not recommended — it creates a warm, moist environment ideal for bacterial growth.

Fungal Ulcer

Natamycin 5% eye drops — every hour initially. Voriconazole drops or oral voriconazole for severe cases or when natamycin fails. Antifungal treatment continues for weeks — fungal ulcers are slow to resolve and require prolonged therapy and close follow-up.

Herpes Simplex Ulcer

Topical acyclovir ointment 5 times daily. Oral acyclovir for severe or recurrent cases. Steroids are absolutely contraindicated in active HSV epithelial disease. Only once the epithelium has fully healed, under specialist supervision, may carefully titrated steroids be considered for stromal disease.

Acanthamoeba Keratitis

Polyhexamethylene biguanide (PHMB) 0.02% drops — initially every hour, round the clock for the first 48 hours, then tapered over weeks to months. Treatment typically continues for 6–12 months. Pain management is a major component of care — these patients are often in significant distress.

When Surgery is Needed

Patients referred late — with deep, central, or perforating ulcers — may require:

  • Tissue adhesive (cyanoacrylate glue) for small perforations with bandage contact lens
  • Therapeutic penetrating keratoplasty — emergency corneal transplant to save the eye in cases of impending or actual perforation
  • Optical keratoplasty — elective corneal transplant after healing to restore vision lost to central scarring

Corneal Scarring — What Happens After the Ulcer Heals

Once an infectious corneal ulcer heals, it leaves a scar. Unlike a skin scar, a corneal scar sits directly in the visual axis. Outcomes range from mild haziness causing minimal vision impact, to a dense white leucoma that completely blocks light transmission.

For patients with visually significant corneal scarring, options include:

  • Rigid gas-permeable contact lenses — masks irregular astigmatism in some patients
  • Deep anterior lamellar keratoplasty (DALK) — replaces scarred corneal layers while preserving the patient’s own endothelium; lower rejection risk than full-thickness transplant
  • Penetrating keratoplasty (PK) — full-thickness corneal transplant for deep or full-thickness scars
  • Phototherapeutic keratectomy (PTK) — laser treatment to smooth superficial corneal scars

Both DALK and PK are performed at Bangladesh Eye Hospital by Dr. Ashraful Huq.

Prevention — What Every Patient Can Do

Agricultural workers:

  • Wear protective eyewear during harvesting and fieldwork
  • Wash any eye injury immediately with clean water — then seek eye care within 24 hours
  • Do not rub plant material or soil into an injured eye

Contact lens wearers:

  • Never sleep in lenses
  • Never use tap water to clean, rinse, or store lenses
  • Never swim with lenses
  • Replace lenses and cases on schedule
  • Remove lenses immediately if the eye becomes red, painful, or uncomfortable

Everyone:

  • Never use steroid eye drops without an ophthalmologist’s prescription
  • Never apply traditional remedies to an injured or infected eye
  • Seek urgent care for any red, painful eye that does not clearly improve within 24 hours

Dr. Ashraful Huq’s Clinical Perspective

The pattern I see most in referred corneal ulcer patients follows a consistent and entirely preventable sequence: eye injury → traditional remedy applied → 2–3 days delay → steroid drops prescribed at a local pharmacy → rapid ulcer progression → referral to me with a near-perforating ulcer.

Each step in that chain is avoidable. The injury itself is often unavoidable. Everything that follows — the remedy, the delay, the steroid — is a choice, usually made out of habit, cost concern, or lack of awareness.

A corneal ulcer caught early costs a bottle of antibiotic drops and a few follow-up visits. Caught late, it may cost the cornea — and with it, functional vision in that eye for life.

If you have any concern about your eye after an injury, or a red painful eye that is not improving — come and be seen. Early assessment is always better, always safer, and always cheaper than managing the consequences of delay.

Frequently Asked Questions

What is a corneal ulcer?
A corneal ulcer is an open wound extending into the corneal layers, caused by bacterial, fungal, viral, or amoebic infection. It is an eye emergency. Without correct and prompt treatment it can permanently damage vision or cause loss of the eye.

How do I know if I have a corneal ulcer?
Key signs: a white or grey spot on the cornea, eye pain, redness, light sensitivity, watering, and blurred vision — particularly after an eye injury. Seek urgent specialist eye care immediately if you have these symptoms.

What is the treatment for a corneal ulcer in Bangladesh?
Treatment depends on the cause: intensive topical antibiotics for bacterial ulcers, natamycin antifungal drops for fungal ulcers, acyclovir for HSV. Severe cases may need corneal transplantation. Available at Bangladesh Eye Hospital, Dhaka under Dr. Ashraful Huq.

Are steroid eye drops safe for corneal ulcers?
No — not without specialist assessment and confirmed diagnosis. Steroids applied to an active bacterial, fungal, or HSV corneal ulcer cause rapid worsening and risk of perforation. This is the most common cause of preventable blindness from corneal ulcers in Bangladesh.

Can vision be restored after a corneal ulcer scar?
Yes — depending on scar size, depth, and location. Options include rigid contact lenses, DALK, or penetrating keratoplasty (corneal transplant). Both are performed at BEH Dhaka.

Can children get corneal ulcers?
Yes. Children with Vitamin A deficiency are at particularly high risk, and corneal ulcers in children can be rapidly blinding. Children with measles are especially vulnerable. Urgent treatment and Vitamin A supplementation are both required.
