Overview

A cataract is a opacification of the natural intraocular crystalline lens that transmits the light entering the eye onto the retina in the posterior part of the eye. The opacification leads to a decrease in vision and may lead to complete vision loss if left untreated for long. Cataracts are the leading cause of preventable blindness in the world . At present, there is no preventive intervention for the progression of cataracts. The modern cataract surgery, which is the removal of the opacified lens and implantation of a clear intraocular lens (IOL), is the only known and approved treatment for cataract. The cataract surgery involving removal of natural lens and implantation of IOL is the most effective procedure performed in ophthalmology with 3 million Americans choosing to have cataract surgery each year, and with a success rate of 97 percent or higher.
