What are the symptoms of cataracts and how are they addressed through surgery?

Decreased vision.... .. Glare, need for increased lighting are the most common symptoms of cataracts. A cataract is the natural clouding of the lens in the eye. The only treatment available is removing the clouded lens material and replacing it with a lens implant. This implant will not cloud up, and cataracts will not develop again after the procedure.
See below. Common symptoms of cataracts are blurred vision, glare and halos at night, double vision, starbursts and many more. They are caused by clouding and hardening of the natural lens inside the eye that occurs with age, smoking, diabetes and sun exposure. It is corrected by surgically removing the natural lens and replacing it with a clear artificial lens.
