A cataract is a cloudiness that occurs in the lens inside of the eye.
The lens is made mostly of water and protein arranged to let light through. When the protein clumps, light is blocked and the lens appears cloudy.Cataracts are not a disease; we will all develop cataracts as we get older.
A person with cataracts may notice faded colors, problems with light (such as halos, or headlights that seem too bright), or poor night vision.
Your eye doctor can detect the presence of cataracts during a thorough eye exam, including a microscopic examination of the inside of the eye. When vision is impaired to a point where it interferes with daily activities, surgery may be indicated. Surgery is done on an out-patient basis and involves a very small incision, through which the cloudy substance of the lens is removed and replaced with an intra-ocular lens implant (IOL). With today’s technology and surgical techniques most patients find their vision after surgery to be very clear at distance, without the use of glasses.
