What Is Selective Laser Trabeculoplasty (SLT)?

Selective Laser Trabeculoplasty (SLT) is a quick, in-office laser treatment that lowers eye pressure by helping fluid drain through the eye’s natural pathway. If you have open-angle glaucoma or ocular hypertension, SLT can be a first-line option or an alternative when drops are not enough.

What it is: A gentle, targeted laser that improves natural drainage
Time in clinic: About 5–10 minutes per eye
Good for: Open-angle glaucoma, ocular hypertension, patients who cannot tolerate or wish to reduce daily drops

How SLT Works

Numbing drops keep the procedure painless and comfortable.

A special lens helps focus the laser.

The laser applies brief pulses to the trabecular meshwork.

You rest for a short time, then head home the same day.

Who Is a Candidate for SLT?

Selective Laser Trabeculoplasty (SLT) may be a good option if you have been diagnosed with open-angle glaucoma or ocular hypertension and need better control of your eye pressure.

You may be a strong candidate if:

Your current eye drops are not lowering your eye pressure enough
You experience side effects from glaucoma medications
It’s difficult to stay consistent with your drop schedule
You want to reduce your reliance on medications before considering surgery

During your visit, your West Texas Eye Associates doctor will evaluate your eye health, confirm your diagnosis, measure your intraocular pressure, and recommend a personalized treatment plan based on your needs.

What to Expect After SLT

Your doctor may prescribe a short course of anti-inflammatory drops to calm irritation. Mild blur, redness, or light sensitivity may occur for a few hours and then fade. Follow-up visits check pressure and comfort. Many patients see an average of 20–30% pressure reduction that can last 3–5 years or longer. If needed, SLT can be repeated.
