Cataracts are a very common eye condition. As we get older the lens inside our eye gradually changes and becomes less transparent (clear). A lens that has turned misty, or cloudy, is said to have a cataract. Over time a cataract can get worse, gradually making your vision mistier. A straightforward operation can usually remove the misty lens and replace it with an artificial lens to enable you to see more clearly again.
The only effective treatment for cataracts is surgery to remove your cloudy lens and replace it with an artificial lens implant. This is done by an ophthalmologist (eye specialist) at a hospital. Lasers aren't used to remove cataracts and there is no evidence to suggest that changing your diet, taking vitamins or using eye drops can cure cataracts.
