Glaucoma Surgery

This is the most common conventional glaucoma surgery. Your surgeon creates a new tiny drainage channel in your eye to allow fluid to escape, lowering your eye pressure. The new channel is partially covered by a flap of your own tissue, which helps prevent too much fluid from draining out.

The procedure takes approximately 30 to 45 minutes. You will receive local anaesthesia (you are awake but your eye is completely numb) with twilight sedation. Your surgeon will not need stitches to close the new channel, but may place a fine suture in the outer layer of your eye.

Your surgeon implants a small flexible tube (a glaucoma drainage device) into your eye to help fluid drain. This is typically used when trabeculectomy has failed or is unlikely to succeed, such as in certain types of glaucoma or after previous eye surgeries.

The procedure takes approximately 45 to 60 minutes under local anaesthesia and sedation.

MIGS procedures use very small devices and incisions. They are generally less invasive than traditional surgery, have a faster recovery, and carry fewer risks. MIGS is often performed at the same time as cataract surgery.

Your surgeon may offer MIGS if you have mild to moderate glaucoma. Several different MIGS devices are available; your surgeon will discuss which is most suitable for you.
