A cataract is a cloudy area in the lens of the eye. A normal lens is clear and focuses light into the back of the eye. When a cataract develops some of this light is blocked out and or scattered. As this cataract develops, it becomes harder for a person to see.

Cataract surgery - Wikipedia, the free encyclopedia Cataract surgery - Wikipedia, the free encyclopedia

Cataract surgery is the removal of the natural lens of the eye (also called "crystalline lens") that has developed an opacification, which is referred to as a cataract. Metabolic changes of the crystalline lens fibers over the time lead to the development of the cataract and loss of transparency, causing impairment or loss of vision. During cataract surgery, a patient's cloudy natural lens is removed and replaced with a synthetic lens to restore the lens's transparency.
