Glaucoma Surgery

Glaucoma laser therapy

Laser therapies such as selective laser trabeculoplasty (SLT) are aimed at improving the draining of fluid from the eye, which lowers eye pressure. Other laser therapies such as laser iridotomy involve the creation of a microscopic hole in the colored part of the eye (the iris) to allow it to relax away from the drainage channel.

Trabeculectomy surgery

Trabeculectomy surgery involves the creation of a new fluid outflow pathway within the eye’s natural tissues. After trabeculectomy surgery, fluid flows from inside the eye to the space underneath the front clear skin tissue of the eye (the conjunctiva). From there, the fluid gets absorbed into the eye’s tear film and normal blood vessel supply.

Glaucoma drainage implant surgery

Glaucoma drainage implant surgery involves the placement of an artificial filtering device onto the eye wall (the sclera).  The device is connected to a silicone tube which enters the eye to carry fluid away. The fluid is collected at the site of the implant and is then absorbed by the eye’s natural tissues.
Microinvasive glaucoma surgery(MIGS)

Microinvasive surgical procedures are performed through a two millimeter incision in the front clear part of the eye and are designed to enhance the function of the trabecular meshwork. These procedures are often combined with cataract surgery, which can be performed through the same incision.

Microinvasive procedures have a lower risk of complications with faster recovery compared to trabeculectomy and glaucoma drainage implant surgeries
