A cataract is a clouding of the lens, the part of the eye responsible for focusing and producing crisp, clear images. For most people, cataracts are the natural result of aging.
Phaco-emulsification is a modern technique that allows the surgeon to remove the cataract using ultrasound.
During cataract surgery, the lens damaged by the cataract is replaced by an artificial acrylate lens (intraocular lens - IOL).
Only an IOL can restore the vision that existed before surgery. Cataracts are the leading cause of vision loss in adults fifty-five and over.
Eye lesions, certain medications, and diseases such as diabetes and alcoholism may, according to research, be the cause of cataracts.
