At present, despite a great deal of research and numerous over-the-counter remedies, there is no proven nonsurgical treatment to cure or retard the development of cataracts. Those who focus on the relationship between dietary patterns and various diseases see evidence that people whose diets are rich in antioxidants (vitamin A and carotene) may be less likely to develop cataracts. It is unlikely that one can benefit from taking multivitamin supplements in the place of a diet lacking in fruits and vegetables. Prolonged exposure to ultraviolet (UV) light may play a role in the formation of cataracts.
UV protection in glasses, lens or tinted, would be beneficial. Large population studies have shown that cigarette smokers face up to twice the risk, as nonsmokers in developing cataracts. The best way to treat a significant cataract is to remove the old, clouded lens and restore the vision with a replacement lens. The time to have your cataracts removed is when the quality of your vision begins to limit your activities and enjoyment of life.
