A cataract is a cloudy area in the lens of your eye (the clear part of the eye that helps to focus light). Cataracts are very common as you get older.

During surgery, your eye doctor will remove the cloudy lens from your eye and replace it with an artificial lens (called an intraocular lens, or IOL). The surgery lasts about 1 hour and is almost painless. Usually, you'll be awake during cataract surgery.

Cataract surgery takes 10 to 20 minutes to complete, depending on the severity of the condition. You should also plan to spend up to 30 minutes following the surgery to recover from the effects of the  sedative.
