A common misunderstanding is that cataracts can be removed by laser beam. A cataract cannot be made to go away with medication. It must be removed surgically, and there are several methods in use. One method is not necessarily better than another. What is important is not how your cataract is removed, but how well you can see again, without discomfort, after the eye is healed.
Cataract surgery is one of the most successful surgical procedures in medicine.
At the time of surgical removal of the cataract, your eye's lens is usually replaced with a permanent artificial lens implant. Occasionally, vision is corrected with thick glasses or a contact lens. Occasionally, a cataract may conceal the presence of retinal detachment, tumor, or other ocular disorder. Therefore, if you have a cataract, regardless of whether or not you are planning to have it removed, you should be examined at intervals prescribed by your doctor to prevent permanent loss of sight from other causes. Generally, glaucoma is caused by an abnormally high pressure inside your eye, which, if untreated, can result in slowly progressive loss of vision.
