A cataract is a clouding of all or part of the normally clear lens within your eye, which results in
blurred or distorted vision. Cataracts are most often found in persons over age 55, but
they are also occasionally found in younger people.
No one knows exactly what causes cataracts, but it is known that a chemical
change occurs within your eye to cause the lens to become cloudy. This may be due to
advancing age, heredity or an injury or disease. Excessive exposure to ultraviolet
radiation in sunlight, cigarette smoking or the use of certain medications are also risk
factors for the development of cataracts.
Although cataracts develop without pain or discomfort,
there are some indications that a cataract may be forming. These include blurred or hazy
vision, the general dimming and/or yellowing of the vision, increased sensitivity to glare
or the feeling of having a film over the eyes.
Currently, there is no proven method to prevent cataracts
from forming. During a comprehensive eye examination, Dr. Wallace or Dr. Hamilton can
diagnose a cataract, then monitor its development and prescribe changes in eyeglasses or
contact lenses to maintain good vision.
If your cataract develops to the point that it affects
your daily activities, Dr Wallace or Dr Hamilton can refer you to an eye surgeon who may
recommend surgery. During the surgery, the eye's natural lens is removed and is replaced
with a plastic artificial lens. After surgery, you can return to your optometrist for
continuing care.
