A cataract is a clouding of the eye’s natural lens inside the eye. The word cataract is derived from a Greek word meaning “waterfall” (looking through falling water). Nearly half of the population over 65 will have some degree of cataract formation in their lifetime. Cataracts are most commonly caused by natural chemical changes within the lens of the eye, which is thought to be part of the natural aging process, but can also occur as a result of trauma, life-long UV exposure, certain medications and certain systemic diseases. It is important to note that a cataract is not considered a disease of the eye and presently there is no proven method of prevention. Cataract surgery is the recommended treatment option when both vision and lifestyle functionality is compromised.
