Cataract corresponds to an opacity or clouding that develops in the crystalline lens of the eye. There are several causes for cataracts, but in 90 % of the cases this opacification is age related. The patients concerned initially notice a progressive deterioration of their vision; at a later stage, they have the impression of looking through a waterfall (origin of the term “cataract”). There is also great sensitivity to dazzle.
Surgery is recommended when the progressive loss in vision causes discomfort in everyday life. This discomfort can vary from one person to another. If an operation is necessary, you are advised not to wait too long as a cataract that is advanced could be difficult to operate. One does not recover from a cataract spontaneously and surgery is the only means to treat it. Children afflicted with congenital cataract are operated as early as possible so that the affected eye can develop as naturally as possible.
