A cataract in a human eye

A cataract is when the lens of the eye gets cloudy. It is a treatable medical condition. Cataracts can cause short-sightedness (myopia), which means you cannot see things in the distance but can see things up close.

If not fixed by surgery, some types of cataracts will cause blindness (which means you cannot see anything at all). In a simple operation, the old lens can be replaced by a new plastic one. Many thousands of people have had this operation.

Vision loss may be gradual, painless, and hard to detect until a significant loss has occurred. Depending on the nature and cause, a cataract can develop rapidly over a few months or slowly over many years.

People who have a cataract in only one eye may experience a loss of depth perception, which can make judging where the stairs are and determining the distance of cars driving in front of them difficult.

Surgical removal is the only known effective cure for cataracts after Cataract Surgery Intra Ocular Lens[1] (IOL) is implanted through the opening created and placed inside the eye in place of the natural lens that has been removed.
