What is Cataract?

A patient affected by cataract gets a gradual decrease in vision, because opacification of the lens prevents light from reaching the retina, at the back of the eye.It can affect the ability to appreciate colours, changes of contrast, as well as day-to-day activities such as driving, reading, seeing through bright lights, and even identifying familiar faces. It is the most common cause of blindness. Age is the most common factor, though other causes exist.

Symptoms

Blurry Vision.

The symptoms of early cataracts may be improved with new eyeglasses, brighter lighting, anti-glare sunglasses, or magnifying lenses. If these measures do not help, surgery is the only effective treatment. Surgery involves removing the cloudy lens and replacing it with an artificial lens.

Cataract surgery is fairly simple and can greatly improve vision in people with severe cases. In rare instances, (as with all surgery) there are risks of infection and discomfort. However, most cataract surgeries are completed in the same day and will not require overnight stay.
