Cataract is an eye problem in which the sufferer experiences blurry vision because of the clouding of the eye lens; it mostly develops with an increasing age, but can also occur because of trauma or severe eye infections. The chief symptoms of cataract are hazy, double vision and an augmented sensitivity towards light. Cataract surgery is the only treatment for removing cataract during which the surgeon removes the affected lens and replaces it with a new lens for restoring normal vision.
