Abstract A cataract is a clouding or opacification of the normally clear lens of the eye or its capsule (surrounding transparent membrane) that obscures the passage of light through the lens to the retina of the eye. This blinding disease can affect infants, adults, and older people, but it predominates the latter group. It can be bilateral and vary in severity. The disease process progresses gradually without affecting daily activities early on, but with time, especially after the fourth or fifth decade, the cataract will eventually mature, making the lens completely opaque to light interfering with routine activities. Cataracts are a significant cause of blindness worldwide. Treatment options include correction with refractive glasses only at earlier stages, and if cataract mature enough to interfere with routine activities, surgery may be advised, which is very fruitful.TheWHO/NPCB(NationalProgrammefor Control of Blindness) survey has shown that there is a backlog of over 22 million blind eyes (12 million blind people) in India, and 80.1% of these are blind due to cataracts. The annual incidence of cataract blindness is about 3.8 million
