What is Selective laser trabeculoplasty (SLT)?
One of the most common laser surgeries performed for open-angle glaucoma is selective laser trabeculoplasty (SLT). Glaucoma causes fluid buildup in the eye, leading to rising intraocular pressure, damage to the optic nerve, and vision loss. SLT is designed to help control and/or reduce intraocular pressure by getting fluids to drain more effectively from the eye. This procedure can lower intraocular eye pressure by up to about 25% in many patients. Our vision experts at West County Ophthalmology perform this minimally invasive laser procedure as well as many other procedures to manage intraocular pressure and slow the progression of glaucoma. If you have been diagnosed with glaucoma, contact one of our facilities in Chesterfield or O'Fallon, MO to learn more about your treatment options including selective laser trabeculoplasty.
How is SLT performed?
The selective laser trabeculoplasty (SLT) procedure is typically performed on an outpatient basis. Prior to beginning your treatment, your ophthalmologist will numb your eyes with anesthetic drops so that you feel minimal discomfort. From there, the ophthalmologist will hold a special lens over your eye and target your trabecular meshwork between the lens and iris with the laser. You may see bright flashes of light but should experience very minimal pain. When completed, the treatment should result in better fluid drainage from your eye's trabecular meshwork.
Your ophthalmologist will schedule one or more follow-up appointments to check on your healing progress and measure your intraocular pressure. Some patients are able to discontinue glaucoma medications after SLT; your ophthalmologist will verify if this option is available to you in the weeks following your surgery.
What Are the Benefits of SLT?
SLT offers a safe and effective way to manage open-angle glaucoma by reducing intraocular pressure through a minimally invasive laser procedure. This treatment enhances the eye's natural fluid drainage, making it a great alternative for patients who have difficulty with medications. Benefits include:
- Quick, minimally invasive procedure with no need for incisions
- Reduced intraocular pressure without daily medications
- Little to no discomfort during and after the procedure
- A repeatable treatment option if pressure increases again
- Short recovery time with most patients resuming normal activities soon after
Selective Laser Trabeculoplasty FAQ
Do the effects of SLT wear off?
The results of your SLT should last between 1 – 5 years. Treatment may be repeated again once results start to wear off.
Are eye drops still necessary after having SLT?
While some people may not need glaucoma medication after this treatment, others will. We will work with you to determine if you still need to take eye drops after your treatment and if your medication can be reduced.
What can I do after my treatment?
After your treatment, you may drive home. We ask that you do not perform any strenuous activities for two weeks after your treatment or until otherwise noted by our team.
