Best Cataract Surgery in Delhi

What a cataract is — and what the surgery does

A cataract is the clouding of the eye's natural lens, the clear disc that sits behind your pupil and focuses light onto the retina. As the proteins in that lens clump together with age, the lens turns from clear to milky, and your vision fades the way a clean windscreen slowly fogs over. Cataract surgery removes that clouded lens and replaces it with a tiny artificial one, called an intraocular lens (IOL). It is the most commonly performed operation in the world, and in most cases it restores clear sight within days.

Why cataracts happen

Age is by far the biggest cause — most people develop some lens clouding after 60. But it is not only about getting older. Long-term diabetes, years of unprotected sun exposure, smoking, an earlier eye injury, and the prolonged use of steroid medicines all speed cataracts up. Some babies are born with them, and a few people develop them young because of a family history. If you have diabetes, your cataract may arrive a decade earlier than your neighbour's.

Symptoms to watch for

• Blurry, cloudy or "misty" vision that glasses no longer fix
• Glare and halos around headlights and streetlights at night
• Colours looking faded or yellowed
• Needing brighter light to read, and frequent changes to your spectacle number
• Double vision in one eye

These come on slowly, so it is easy to miss how much you have lost until one eye is tested against the other.

What to do first

See an ophthalmologist (an eye surgeon) for a dilated eye exam. Not every cataract needs surgery straight away — early on, a stronger spectacle number and better lighting may be enough. Surgery is advised when the cloudiness starts to interfere with everyday life: driving at night, reading, cooking, recognising faces, or working. There is no benefit in waiting for a cataract to "ripen"; in fact a very dense, over-ripe cataract is harder and riskier to remove.

The procedures — how it is actually done

Phacoemulsification (phaco)

This is the modern standard. The surgeon makes a 2–3 mm incision, uses an ultrasound probe to break the cloudy lens into fragments, gently suctions them out, and slides a foldable IOL into place. It is done under local anaesthetic drops in 15–20 minutes, usually stitch-free, as day-care. You go home the same day.

Femtosecond laser-assisted surgery (FLACS)

Here a laser performs some of the steps — the incision and the opening in the lens capsule — that the surgeon otherwise does by hand. It adds precision and cost, but for a routine cataract most surgeons find results are similar to good manual phaco.

Manual small-incision surgery (MSICS)

A low-cost, sutureless technique used widely in India's public and charity hospitals. It does not need the expensive phaco machine, delivers excellent results in trained hands, and is the workhorse of India's mass cataract programmes.

Which option is safest, with the fastest recovery?

For most people, phacoemulsification with a monofocal IOL is the safest, quickest-recovery choice — small wound, no stitches, most patients see clearly within 24–48 hours and are back to light routine in 2–3 days. FLACS is a reasonable option if your surgeon recommends it for a specific reason, but it is not automatically "better" for a straightforward cataract. MSICS is the sensible, high-quality choice when budget is the priority. The single biggest factor in a safe result is not the machine — it is an experienced, high-volume surgeon and a clean, well-equipped theatre, which is exactly what the verification and ratings on this page help you find.

Risks and what to expect

Cataract surgery is very safe — serious complications occur in well under 1 in 100 cases. Mild grittiness, watering and light sensitivity for a few days are normal. You will use antibiotic and anti-inflammatory drops for about four weeks and avoid rubbing the eye, swimming, and dusty or heavy work during that time. A small number of people develop a cloudy film behind the new lens months or years later (posterior capsule opacification) — this is fixed painlessly in a few minutes with a YAG laser in the clinic, no fresh surgery needed. Warning signs that need a same-day call to your surgeon are increasing pain, sudden vision loss, or a red, discharging eye.
