Cataracts

cataractA cataract is a clouding of the eye’s lens that causes loss of vision. The lens is located behind the iris and pupil. It focuses light onto the retina at the back of the eye. It adjusts to allow us to see clearly both up close and far away.

The lens is made of mostly water and protein. As we age, this lens material begins to opacify. This is a cataract. This may worsen over time, making it difficult to see.

Cataracts have little effect on vision at first. Vision may become a bit blured, like looking through a dirty window. You may also begin to notice glare from lights and say that colors seem to be faded.

Cataracts are treated with surgery. The clouded lens is removed and most often replaced with a clear, plastic lens. This is usually an outpatient procedure. You will be instructed to use eye drops and an eye shield while sleeping while your eye heals. This procedure is very successful in restoring vision. Research is showing that there may be several contributors to cataract formation including smoking, diabetes, ultraviolet sunlight and normal aging changes of the eye.
