Cataract Surgery

What it involves

Cataract surgery replaces the eye's cloudy natural lens with a clear artificial lens. The surgeon, an ophthalmologist, usually removes the lens through a small cut in the front of the eye and places the new lens in the same position. It is normally done as day surgery, under local anaesthetic.

Who it is for

It is for people whose vision has become clouded by a cataract to the point that it affects everyday activities such as reading, driving or recognising faces. The World Health Organization identifies cataract as a major cause of blindness worldwide, and surgery is the recognised treatment when it is needed.

How long it usually takes

The operation itself is often short, and you generally go home the same day. Planning, tests beforehand and follow-up add further visits.

What to expect

Before surgery you have an eye examination and measurements to choose the lens. On the day the eye is numbed, and you stay awake. Afterwards you wear a shield and are given instructions. A follow-up examination checks healing.

Aftercare

Follow the instructions about eye drops, protecting the eye and avoiding rubbing it. Avoid swimming and dusty places as advised. Contact your surgeon at once if you notice increasing pain, worsening vision or redness.

When to seek it

See an optometrist or ophthalmologist if your vision seems cloudy, glare is troubling you or you are finding daily tasks difficult. Sudden vision loss needs urgent attention.

What affects the cost

Cost depends on the type of lens chosen, the surgeon and facility, tests before and after, and whether one or both eyes are treated. HealthNaro shows a price only where a clinic has supplied a figure with a source and date.
