A cataract is a clouding of the normally clear lens of the eye which can obscure vision just as steam fogs a window. Cataracts usually develop slowly and may not be noticed until vision loss begins to interfere with the tasks of daily living.
The only accepted treatment for cataracts is surgery, where the entire lens of the eye is removed. Usually it is replaced by a clear plastic lens, or your doctor may prescribe special eyeglasses or contact lenses after surgery. Fortunately, you can usually have cataract surgery right in the doctor’s office and go home the same day.
More than 95 percent of people who have cataract surgery report improved vision. If you are experiencing blurred vision or feel discomfort from bright lights, call your doctor. He or she may advise you to see an ophthalmologist, a medical doctor licensed to treat all eye conditions.
