WHAT IS LASER TRABECULOPLASTY?
Laser trabeculoplasty is a laser eye procedure used to treat open-angle glaucoma.
​
In people with glaucoma, the aqueous humor does not drain effectively from the front part of the eye. As fluid builds up, pressure inside the eye increases and can damage the optic nerve. If glaucoma is not treated, it can eventually lead to vision loss and blindness. Laser trabeculoplasty improves fluid drainage, helping to reduce eye pressure.
​
Although this procedure cannot reverse damage that has already occurred to the optic nerve, it can help prevent additional vision loss caused by glaucoma.

HOW IS LASER TRABECULOPLASTY PERFORMED?
Laser trabeculoplasty is typically performed in an outpatient surgical facility or at your ophthalmologist’s office. During the procedure, laser energy is applied to the eye’s drainage angle to improve its function. As the drainage system works more efficiently, eye pressure gradually decreases.
​
Laser trabeculoplasty is a relatively quick procedure and usually takes less than 10 minutes. The process generally includes the following steps:
​
-
Numbing eye drops will be placed in your eye to keep you comfortable during the procedure.
-
Your ophthalmologist will place a special contact lens on your eye to help guide the laser accurately.
-
The laser will be directed at the drainage angle of your eye. You may notice a mild stinging or tingling sensation during treatment.
-
Your vision may remain blurry for a few hours after the procedure, so it is recommended that someone drive you home.
-
Your ophthalmologist may prescribe medications or eye drops to use for several days following the treatment.
​
It may take approximately six to eight weeks before laser trabeculoplasty reaches its full effect in lowering eye pressure. If your eye pressure remains elevated three months after treatment, additional care may be needed. Your ophthalmologist may recommend another laser procedure, additional glaucoma medications, or a different type of eye surgery.
WHAT ARE THE RISKS OF LASER TRABECULOPLASTY?
​As with any surgical procedure, laser trabeculoplasty involves some potential risks. Fortunately, serious complications are uncommon. Possible risks include:
-
The procedure may not reduce eye pressure enough to control glaucoma.
-
Eye pressure may increase after treatment, requiring medication or further surgery.
-
The eye may become red, swollen, irritated, or painful.
-
Temporary blurred vision may occur.
-
The laser could accidentally damage other structures within the eye.
-
Additional laser trabeculoplasty treatments may be necessary in the future.

Your ophthalmologist will discuss both the benefits and potential risks of laser trabeculoplasty before the procedure and answer any questions you may have.​
