Cataract removal is a procedure that removes the lens of the eye that has become clouded. Naturally eyes allow light rays to clearly focus on the back of the eye. When a cataract is present the light rays become blocked and the vision becomes cloudy.
Surgery
Cataract removal is performed by making a small incision at the edge of the outer lining of the eye. A special microscope is used. The lens can be removed in several ways:
with surgical tools
with a "cold" surgical instrument- with an instrument and machine that uses "sound waves" to break up the lens and remove it
- with a laser tool and machine
An artificial lens may be placed inside the eye to correct vision without glasses or contact lenses. The incision is closed with fine stitches.
