What is a Cataract?
A cataract is a clouding of the lens of the eye. Depending upon its size and location, it can interfere with normal vision.
The lens of the eye help to focus images into the retina – which transmit the image through the optic nerve to the brain.
However, if the lens is clouded by a cataract, light is scattered so the lens no longer focus it properly, causing vision problems. Cataracts are the leading cause of vision loss in the usa and it is the leading cause of blindness in the world.
The exact cause of cataract is unknown, most often cataract is considered as a part of getting older but cataracts can sometimes be found in young people or even newborn babies. Unlike many eye diseases, vision loss due to cataract can be restored. Cataract surgery is one of the most commonly performed procedures in the usa and has a 95% success rate.
