Cataracts Causes, Symptoms, Vision Tests and Surgery

What is the prognosis of cataracts?

The rate of progression of cataracts is usually predictable and surgery is successful in restoring vision in a large majority of cases. If other diseases are present within the eye, the degree of visual improvement will be limited by the other disease process. Ophthalmologists can usually determine this in advance.

Can cataracts be prevented?

Everyone, if they live long enough, will develop cataracts. There is no scientifically proven method that prevents the inevitable. Progression of cataracts can be slowed by avoiding large amounts of ultraviolet light, not smoking, and following a healthy diet. Wearing UV-protection sunglasses when exposed to sunlight can be helpful.
