Dentistry is a branch of medicine that is involved in the study, diagnosis, prevention, and treatment of diseases, disorders and conditions of the oral cavity, commonly in the dentition but also the oral mucosa, and of adjacent and related structures and tissues, particularly in the maxillofacial (jaw and facial) area.
En EspaÃ±ol Read in Chinese. An intraocular lens implant is a synthetic, artificial lens placed inside the eye that replaces the focusing power of a natural lens that is surgically removed, usually as part of cataract surgery [See figures 1 and 2].
A cataract is a painless, cloudy area in the lens of the eye. The lens is enclosed in a lining called the lens capsule. Cataract surgery separates the cataract from the lens capsule. In most cases, the lens will be replaced with an intraocular lens implant (IOL).If an IOL cannot be used, contact lenses or eyeglasses must be worn to compensate for the lack of a natural lens.ome complications can be treated and vision loss reversed, but others cannot. Complications that may occur with cataract surgery include: 1  Infection in the eye (endophthalmitis). 2  Swelling and fluid in the center of the nerve layer (cystoid macular edema). 3  Swelling of the clear covering of the eye (corneal edema).
