Current status of the treatment of cataract.

Abstract

Cataract, a leading cause of blindness, has been successfully treated by surgery since ancient times. Surgical methods have evolved from couching, to extraction, to phacoemulsification. Cataract surgery is now an outpatient procedure that can be performed with topical anesthesia. Intraocular lens implants restore natural vision without thick glasses and contact lenses. Current procedures are highly successful in restoring vision.
