Frequency, Causes and Cutting-Edge Treatment of Cataract: A Review

Cataract is the disease which is prevailing world wide rapidly and health care professionals are making serious efforts to investigate the latest, inexpensive and readily available treatment of the disease. The aim of this review was to investigate the pervasiveness, causes and latest treatment of cataract. However this is a cross sectional study in which we study that Cataract occurs when protein is buildup in the lens and makes it cloudy. So the passing of light clearly through the lens is disturbed thus vision is lost up to some extent. Since on the outside of the lens new lens cells are formed, all the older cells are compacted into the center of the lens resulting in the cataract. Beside of this oxygen free radicals are also involved in cataract because its overproduction can stop the reach of glutathione and other antioxidant into lens where it ceases action of oxidant. Genetically prevalence of cataract also possessed. The gene responsible for cataract is Gamma-S crystalline gene (CRYGS).The only way of cataract removal is surgery although some medication are also present but it is not enough evidence that these lowers the risk for cataract formation.
