The most commonly performed eye surgery is to remove cataract, a clouding of the crystalline lens inside the eye. More than 300,000 cataract surgeries are carried out in the UK each year, in addition to many other types of routine and emergency eye surgery. The human eye is second in complexity only to the brain, requiring great care and skill to restore and repair.

What causes cataracts?

Cataracts are a normal part of ageing, but can also occur in response to injury or inflammation or even as an inherited feature. Not all cataracts require surgery but if they make daily activities difficult the only way to restore vision is to remove them and insert an artificial lens implant.

What are the symptoms of cataracts?

As cataracts progress vision becomes hazy and increasingly blurry. Your appreciation of colour changes but this can be subtle over time. Bright sunlight and headlights on cars at night may seem particularly bright and dazzling.

About The Surgery

Cataract surgery is a relatively straightforward procedure carried out under a local anaesthetic in most cases and normally takes approximately 30 minutes.

During the operation the cloudy lens is removed and replaced with a small plastic lens, called an intraocular lens (IOL).

It is normal to be prescribed eye drops to use for a short time after the operation to reduce inflammation and prevent infection. It is important to keep the eyelid area clean after the operation.
