Marji developed cataracts about two years ago, clouding her vision. She is legally blind in her right eye and the vision in her left eye is deteriorating quickly. She visits Dr. Kerry Assil, who explains that a cataract is the loss of transparency of the natural lens inside the eye. Cataracts are the No. 1 cause of blindness worldwide, but Margie developed them early, and Dr. Assil performs a revolutionary new surgery to remove them.
