Cataract (operation) - Definition

January 2017


Definition


A cataract is a condition affecting the eye and resulting in the gradual clouding of the lens. When it is completely clouded, the light no longer passes through and the vision of the affected eye is no longer possible. Cataract surgery is the surgery performed most often throughout the world and aims to restore proper vision. It is performed under local or general anesthesia, and involves removal of the damaged lens which is replaced with an implant. Other techniques using lasers are also sometimes practiced.
