The surgery done for cataract involves removal of opacified lens and placement of artificial lens known as intra-ocular lens (IOL). The surgery is done under local anaesthesia or general anaesthesia. Local anaesthesia involves application of drops and gel to make the procedure pain free. It also involves injection of drug around the eye. General anaesthesia will be required in case of children, special situations in adults like psychiatric patients who are not co-operative.
Surgery is usually done using ultrasound energy to remove the cataract (not using Laser which is a common misconception). This procedure does not require placement of sutures (stitch- free). In few cases where this procedure is not safe, then the surgery will be done manually by a larger incision and placement of sutures.
