Which part of a human eye is removed during a cataract operation ?

Question

What thin, circular structure in the eye controls the diameter and size of the pupil and the amount of light reaching through it?

Answer 1

In cataract surgery, the lens inside your eye that has become cloudy is removed and replaced with an artificial lens (called an intraocular lens, or IOL) to restore clear vision. The procedure typically is performed on an outpatient basis and does not require an overnight stay in a hospital or other care facility.
