A cataract is the cloudiness of the eye’s lens which affects the normal vision. It is a surgery that is done to restore the clear vision, by removing the clouded lens of the eye. This is replaced by an artificial lens called ‘intraocular lens’, made from plastic, acrylic or silicone, and functions in the same way as the natural lens of the eye.
