How are cataracts treated?
Because a cataract is a clouding of – not a film over – your lens, surgery is the only way to remove cataract once it is formed.
The operation involves making a small 3 mm opening in the front surface of the eye, through which is put a small instrument that breaks the cataract up into smaller pieces so that it can be removed. This is called phacoemulsification. After that a small clear plastic lens (intraocular lens or IOL) is put into the eye to take the place of the cloudy lens.
The whole operation takes around half an hour. Surgery is done on only one eye at a time. That way you can use the other eye while the eye that is operated on heals.
