Everything You Need to Know About Cataract Surgery in Bangladesh
A cataract is a clouding of the eye’s natural lens that gradually blurs vision, making everyday tasks like reading, driving, and recognizing faces more difficult. It is one of the leading causes of preventable blindness worldwide — and one of the most successfully treated conditions in modern ophthalmology.
In Bangladesh, cataracts are extremely common, particularly in adults over 50. The good news: cataract surgery in Bangladesh is safe, effective, and widely accessible — and with the right surgeon, most patients regain clear vision within days.
Cataracts can affect one eye or both eyes independently. They do not spread from eye to eye, but both eyes may develop cataracts at different rates over time.
| Key Fact: | Cataracts are not a growth on the eye. They are a change inside the lens itself — the clear disc behind your pupil that focuses light onto the retina. As proteins in the lens break down with age, the lens becomes cloudy. |
The crystalline lens is a transparent, flexible disc located just behind the pupil and iris. Its primary job is to focus light precisely onto the retina — the light-sensitive layer at the back of the eye — so you see sharp, clear images at all distances.
A healthy lens is completely clear. It works like the lens of a camera, constantly adjusting its shape (a process called accommodation) to bring near and far objects into focus.
When a cataract forms, proteins within the lens clump together and the lens loses its clarity. This is why vision becomes foggy, dull, or hazy — like looking through a frosted or dirty window.
Cataracts most commonly develop as a natural part of the ageing process. Most people begin to notice subtle changes in their vision from their mid-40s onwards, though significant vision impairment from cataracts is more common after age 60.
That said, cataracts are not exclusively an older person’s condition. They can also appear earlier in life due to:
- Previous eye injury or trauma
- Prolonged use of corticosteroid medications
- Diabetes or metabolic conditions
- Excessive UV exposure without eye protection
- Previous eye surgery for other conditions
- Congenital causes (present from birth)
In Bangladesh’s climate, prolonged sun exposure without UV-protective sunglasses is a contributing factor to earlier cataract development. Regular eye check-ups after age 40 are strongly recommended.
While age is the single biggest risk factor, the following groups have a higher likelihood of developing cataracts:
| Risk Factor | Why It Increases Risk |
|---|---|
| Age (50+) | Natural protein breakdown in the lens accelerates with age |
| Diabetes | High blood sugar accelerates lens clouding |
| Excessive sun exposure | UV-B radiation damages lens proteins over time |
| Smoking | Increases oxidative stress in the eye |
| Family history | Genetic predisposition to early cataract formation |
| Eye injury or surgery | Trauma can accelerate or trigger lens clouding |
| Steroid medications | Long-term use can cause posterior subcapsular cataracts |
| Malnutrition | Deficiencies in antioxidants (Vit C, E) linked to higher risk |
Important: Having one or more risk factors does not mean you will definitely develop a cataract. Regular eye examinations with a qualified ophthalmologist in Dhaka can catch early changes before they significantly affect your vision.
Cataracts develop slowly and symptoms are often subtle at first. Many patients do not notice significant vision changes until the cataract has become moderately advanced. Common symptoms include:
- Blurred, hazy, or cloudy vision — as if looking through fog or frosted glass
- Increased sensitivity to glare from sunlight, headlights, or bright lights
- Faded or yellowed colours — the world looks less vivid
- Poor night vision — difficulty driving or seeing in dim light
- Seeing halos around lights, especially at night
- Frequent changes in glasses or contact lens prescription
- Double vision in one eye (not corrected by closing the other eye)
- Needing brighter light for reading or close work
| When to Act: | If you are experiencing any of the above symptoms — especially if they are interfering with daily life — do not delay. Early assessment by a cataract specialist in Dhaka can confirm the diagnosis and plan the safest, most appropriate treatment. |
Yes. Cataracts are classified by their location within the lens and their cause. Understanding the type helps determine the best surgical approach.
| Type | Location | Common Cause |
|---|---|---|
| Nuclear cataract | Centre of the lens | Most common; age-related; causes progressive myopia then cloudiness |
| Cortical cataract | Outer edges of the lens | Diabetes, UV exposure; spoke-like opacities radiating inward |
| Posterior subcapsular cataract | Back of the lens capsule | Steroid use, diabetes; causes glare and near-vision problems early |
| Anterior subcapsular cataract | Front of the lens capsule | Often trauma or atopic dermatitis-related |
| Congenital cataract | Present at birth | Genetic or infection during pregnancy; requires early treatment |
| Traumatic cataract | Any location | Following blunt or penetrating eye injury |
Cataract diagnosis is straightforward and painless. Dr. Ashraful Huq performs a comprehensive eye examination that includes:
- Visual acuity test — measures how clearly you can read letters at a standard distance
- Slit-lamp examination — a specialised microscope that allows detailed inspection of the lens and other eye structures
- Dilated eye exam — drops widen the pupil so the lens and retina can be examined thoroughly
- Tonometry — measures intraocular pressure to rule out glaucoma as a contributing factor
- Retinal assessment — confirms the retina is healthy and will benefit from cataract removal
Biometry (IOL calculation): Before surgery, precise measurements of your eye are taken to calculate the exact power of the intraocular lens (IOL) required. This ensures the best possible vision outcome after cataract surgery in Bangladesh.
The only proven, effective treatment for cataracts is surgical removal. Unlike refractive errors, cataracts cannot be corrected with glasses, eye drops, or medication. Once a cataract significantly affects your quality of life, surgery is the recommended course of action.
The good news: cataract surgery is among the most performed and most successful surgical procedures in the world. In experienced hands, the procedure takes 15–20 minutes and is performed under local anaesthesia — meaning you are awake but feel no pain.
Dr. Ashraful Huq performs cataract surgery using the latest phacoemulsification (Phaco) technique at BEH (Bangladesh Eye Hospital) in Dhaka — one of Bangladesh’s leading eye care institutions.
The standard, gold-standard technique for cataract surgery in Bangladesh is Phacoemulsification (Phaco) — a minimally invasive procedure that removes the cloudy lens through a tiny incision of just 2–3 mm.
Here is a step-by-step overview of what happens during your procedure:
| Step | What Happens |
|---|---|
| 1. Anaesthesia | Anaesthetic eye drops numb the eye. You remain comfortable and awake throughout. No injections or general anaesthesia are required in most cases. |
| 2. Micro-incision | A precise incision of 2–3 mm is made at the edge of the cornea. This self-sealing incision typically requires no stitches. |
| 3. Lens capsule opening | A circular opening (capsulorhexis) is created in the thin membrane surrounding the lens, allowing access to the cataract. |
| 4. Phacoemulsification | An ultrasound probe breaks the cloudy lens into tiny fragments, which are then gently suctioned out of the eye. |
| 5. IOL implantation | A foldable artificial intraocular lens (IOL) is inserted through the same small incision and unfolds into the exact position of the natural lens. |
| 6. Incision sealing | The incision self-seals without sutures. A protective shield is placed over the eye. |
Total procedure time: 15–20 minutes per eye. Recovery: Most patients notice improved vision within 24–48 hours.
Femtosecond laser-assisted cataract surgery (FLACS) is an advanced option that uses a precise laser to perform several of the most technically demanding steps of cataract surgery — including the corneal incision, lens capsule opening, and initial lens fragmentation.
Benefits of laser cataract surgery include:
- Greater precision in lens capsule opening — improving IOL centration and visual outcomes
- Reduced ultrasound energy used inside the eye — faster healing
- More accurate astigmatism correction — ideal for patients with corneal astigmatism
- Particularly beneficial when using premium multifocal or toric IOLs
| Is Laser Cataract Surgery Right for You? | Laser cataract surgery is an excellent option for patients seeking the highest precision, especially when combined with premium lens implants. Dr. Ashraful Huq will advise whether standard Phaco or laser-assisted surgery is most appropriate for your specific case. |
The intraocular lens (IOL) implanted during your cataract surgery is permanent and plays a critical role in your vision after surgery. Dr. Ashraful Huq will recommend the most appropriate lens based on your lifestyle, visual goals, and eye measurements.
Monofocal IOLs
Best for: Patients happy to use reading glasses for near tasks.
Monofocal IOLs provide excellent clarity at a single focal distance — typically set for distance vision (e.g., driving, watching TV). They are the most commonly used lenses in cataract surgery in Bangladesh and are covered by most insurance and hospital packages.
- Clear, sharp distance vision
- Most affordable and widely available option
- Reading glasses typically still needed for close work
Toric IOLs
Best for: Patients with pre-existing corneal astigmatism.
Toric IOLs are specially designed to correct astigmatism at the same time as removing the cataract. Without a toric IOL, a patient with significant astigmatism would still require glasses for clear vision at all distances even after successful cataract surgery.
- Corrects astigmatism at the time of surgery
- Reduces dependence on glasses for distance vision
- Requires precise surgical alignment for optimal results
Best for: Patients who want to reduce or eliminate glasses for most activities.
Premium multifocal and trifocal IOLs are engineered to provide clear vision across multiple distances — near, intermediate, and distance — by splitting incoming light into different focal points. Many patients with these lenses can read, use a phone, use a computer, and drive without glasses.
- Near, intermediate, and distance vision in one lens
- Significantly reduces or eliminates need for glasses after surgery
- Some patients may experience mild halos or glare in low light — typically reduces over weeks
- Requires a thorough assessment to confirm suitability
| Dr. Huq’s Recommendation: | The ‘best’ IOL is the one matched to your lifestyle and visual demands. During your consultation, Dr. Ashraful Huq will discuss all options clearly and recommend the lens that gives you the best quality of life after cataract surgery in Dhaka. |
Cataract surgery is one of the safest operations performed worldwide, with a success rate exceeding 98% in skilled hands. However, as with any surgical procedure, there is a small risk of intraoperative (during surgery) complications.
Potential intraoperative risks include:
- Posterior capsule rupture — the membrane behind the lens develops a small tear (rare, managed by an experienced surgeon)
- Vitreous loss — gel from the back of the eye enters the surgical field (managed with vitrectomy if needed)
- Zonular dehiscence — weakness of the fibres holding the lens in place
- Corneal oedema — temporary swelling of the cornea
The risk of serious intraoperative complications is significantly reduced when surgery is performed by a highly experienced surgeon. Dr. Ashraful Huq has performed over 5,000 cataract procedures and is trained to identify and manage any intraoperative challenges calmly and effectively.
Post-operative complications are uncommon but important to be aware of. Most are mild and manageable with appropriate treatment.
| Complication | Frequency | Management |
|---|---|---|
| Posterior Capsule Opacification (PCO) — “secondary cataract” | 20–30% (most common) | Quick, painless YAG laser procedure in clinic; restores vision fully |
| Infection (endophthalmitis) | Very rare (<0.1%) | Urgent antibiotic treatment; prevented by strict sterile technique |
| Cystoid Macular Oedema (CMO) | Uncommon | Anti-inflammatory eye drops; usually resolves |
| Raised intraocular pressure | Uncommon | Managed with pressure-lowering drops |
| IOL dislocation | Very rare | Surgical repositioning if required |
| Retinal detachment | Very rare | Surgical repair; more common in highly myopic eyes |
| Post-Op Care: | Dr. Ashraful Huq’s team provides clear post-operative instructions and follow-up appointments to monitor your recovery and ensure the best possible outcome. |
Most patients experience a dramatic improvement in vision within 24 to 48 hours after cataract surgery. Full visual recovery and stabilisation typically occurs within 4 to 6 weeks.
| Timeframe | What to Expect |
|---|---|
| Day 1 (day after surgery) | Vision already noticeably clearer — colours appear brighter and more vivid. Some blurring and mild grittiness is normal. |
| Days 2–7 | Vision continues to improve. Light sensitivity reduces. Eye drops are used to prevent infection and inflammation. |
| Weeks 2–4 | Most daily activities resume normally — reading, working, watching TV. Driving can usually restart after surgeon’s clearance. |
| Weeks 4–6 | Final prescription glasses (if needed) can be prescribed once vision is fully stable. |
| Long-term | Cataract does not return. IOL is permanent. Follow-up checks monitor for PCO and other post-op changes. |
Important: Do not rub the eye, expose it to water (swimming), or miss follow-up appointments during recovery. These simple precautions protect your result and your long-term vision.
