A cataract is a clouding of the lens in the eye, which causes blurry or cloudy vision. The lens is a clear structure in the eye that helps focus light on the retina, which converts the light into electrical signals sent to the brain.

The most common cause of cataract is aging. As people get older, the lens in their eyes becomes less flexible, less transparent, and thicker, causing a buildup of protein within the lens. This protein buildup leads to the clouding of the lens and eventually to cataract.

The main symptoms of cataract are:

·     Blurred or cloudy vision

·     Sensitivity to light

·     Decrease in night vision

·     Seeing halos around lights

·     Need for frequent changes in eyeglass or contact lens prescriptions

The only effective treatment for cataract is surgery. The surgery is performed to remove the cloudy lens and replace it with an artificial lens implant. This procedure is done on an outpatient basis.
