YAG Laser Iridotomy

Iridotomy is a procedure focused on the treatment of narrow-angle glaucoma, primary angle-closure glaucoma and other types of glaucoma associated with pupillary block. It involves making an incision in the iris (the colored part of the eye) to drain the fluid and lower eye pressure, preventing the worsening of vision loss.

How it works

Before iridotomy, eye drops are instilled into the patient’s eye to expand the iris allowing easy access for the laser to make the incision. After a few drops of topical anesthesia, a special lens that acts as both the focal point of the laser light and a barrier between the eyelids to prevent the patient from blinking during the procedure. 

YAG Laser Iridotomy only takes a few minutes and sedation is not required.

Trabeculectomy

Trabeculectomy is a kind of glaucoma surgery that involves creating a pathway in the sclera (the white part of the eye) to drain the fluid, lower eye pressure and prevent worsening of vision loss.

How it works

The procedure is done under the upper eyelid, where an incision is made on the lining of the sclera. A small flap is created underneath the incision, where a pathway allows fluid to drain and lower eye pressure. Once the fluid has been drained, the flap is then sewn closed to prevent the leakage of fluid.
