Cataract in human eye

Cataracts are a clouding of the lens of the eye that result in the slow and gradual loss of vision. They are a combination of several factors including age, denaturing of the proteins of the lens, genetic predisposition and exposure to ultraviolet light or high altitude radiation.

Treatment is with surgery to remove the cloudy lens and replace it with an artificial lens. Although the surgery has a very low complication rate, it is usually not performed unless the cataract interferes with vision.

Left untreated, cataracts will generally progress until vision is completely lost. It is one of the most common causes of blindness in the developing world.
