Cataracts are common as we grow older with the formation of a cloudy area in the lens of eyes.
Some of the symptoms of Cataract- cloudy or blurry vision, faded colors, sensitivity to glare, cannot see clearly at night etc.
However, Cataract can be treated safely. The doctor surgically removes or replaces the natural lens with artificial plastic lens. Patient is given sedative before the operation. It is a short procedure of removing the Cataract which restores a clearer vision of the patient. It is cost effective and safe.
