A cataract is clouding of the lense inside of the eye. There are many types of cataracts, but the most common is the nuclear sclerotic cataract. It is when the entire lense goes from a gradual yellowing to an opaque cloudiness. Age, heredity and UV light exposure are all factors involved in cataract formation. Regardless of what type of cataract it is, the treatment is the same; removal of the cloudy lense and replacing it with a new lense. Surgery is an outpatient procedure usually taking about eight (8) minutes.
