Cataract is a clouding of the eye's natural lens that develops gradually, most often with age. It's one of the leading causes of treatable blindness in India, and in almost every case sight can be fully restored. Our Cataract & IOL Clinic evaluates, monitors, and surgically treats cataracts at every stage, using small-incision phacoemulsification and a range of intraocular lens (IOL) options matched to each patient's eyes and daily needs.
Conditions we treat
- Age-related (senile) cataract — the most common form, typically after age 50–60
- Congenital and developmental cataract in infants and children
- Traumatic cataract following an eye injury
- Secondary cataract associated with diabetes, uveitis, glaucoma, or other eye disease
- Drug-induced cataract linked to long-term steroid use
- Dense or "mature" cataracts needing extra surgical planning
Diagnosis & technology
- Visual acuity testing to measure how the cataract is affecting your vision
- Slit-lamp examination of the lens and front of the eye
- Dilated retinal examination before planning surgery
- Tonometry (eye-pressure check) to rule out coexisting glaucoma
- Needs hospital confirmation: Biometry / IOL power calculation — specific equipment in current use at BSEH
Treatment options
-
Phacoemulsification (sutureless surgery) — a small 2–3mm incision, ultrasound removal of the cloudy lens, and a foldable IOL inserted through the same opening; usually day-care surgery under local or topical anaesthesia
-
Conventional larger-incision surgery, occasionally used for very dense or complicated cataracts
-
Monofocal IOLs — clear distance vision; reading glasses usually still needed
-
Toric IOLs — correct pre-existing corneal astigmatism at the same time
- Needs hospital confirmation: Multifocal / extended-depth-of-focus IOLs — which premium lens options are currently stocked at BSEH
When to seek care
Cataract is usually not an emergency — it develops slowly and can be monitored. See an eye doctor when blurred vision, glare, or night-driving difficulty starts affecting daily life. Seek prompt evaluation for any sudden vision change, eye pain, or a white/grey pupil reflex or squint in an infant, as these need timely specialist assessment.
Frequently asked questions
Is cataract surgery painful?
No. It's done under local or topical anaesthesia — you stay awake but feel no pain, only mild pressure at times.
Do I have to wait until the cataract is "ripe"?
No — with modern small-incision surgery there's no need to wait. Surgery is usually recommended once it starts affecting daily activities like reading or driving.
Will I still need glasses after surgery?
Many patients need little correction for distance with a monofocal lens, but most still use reading glasses for close work unless a presbyopia-correcting lens was chosen.
Can a cataract come back after surgery?
The lens itself cannot regrow, but the thin membrane holding the new IOL can turn cloudy months or years later — this is common, easily treated, and not a sign the surgery failed.
How long is recovery?
Most people notice improved vision within a few days, with full stabilisation over a few weeks, plus a short course of eye drops and a few follow-up visits.
