Cataract Surgery

How is cataract surgery performed?

In cataract surgery, the cloudy cataract lens is removed and then replaced with an artificial lens implant.

Cataract surgery is the main surgery performed at SNEC. The main technique used to remove a cataract is phacoemulsification.

In phacoemulsification:

• A small opening between 1.8mm and 2.75mm is first created on the cornea.
• An ultrasonic device is then introduced through this opening into the eye. This device breaks the cloudy lens up into small pieces and facilitates removal from the eye.
• After the cataract lens is entirely removed, an artificial lens implant is inserted to the same position.
• Most of the time, the wound does not require any stitching.
• This method of cataract surgery takes less than 30 minutes.
• This is a day surgery procedure hence there is no need to stay overnight in the hospital.
• An anaesthetist is with you during surgery to provide sedation that will help you feel comfortable and relaxed during the surgery. You may not be totally asleep during surgery, but will remain comfortable. Anaesthetic eye drops and injections will be given to minimise pain. It is important to cooperate by not talking or moving your head and body during the surgery.
