Selective Laser Trabeculoplasty (SLT) at West Texas Eye Associates
Selective Laser Trabeculoplasty (SLT) lowers eye pressure by improving the eye’s natural drainage, giving many patients a drop-sparing option for glaucoma care in West Texas.
A New Way to Manage Glaucoma, Without the Daily Drops
Have you ever struggled to remember your eye drops or felt frustrated by side effects? Millions of people with glaucoma face the same challenge every day. That’s why Selective Laser Trabeculoplasty (SLT) has become a game-changer—it helps lower eye pressure by improving your eye’s natural drainage system, giving you freedom from the burden of constant medication.
At West Texas Eye Associates in Lubbock, our glaucoma specialists utilize advanced laser systems to deliver precise, gentle treatments that take just a few minutes but can protect your sight for years.
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
Think of SLT as a tune-up for your eye’s natural drainage filter. Over time, this filter—the trabecular meshwork—can clog, raising pressure inside the eye. SLT sends tiny bursts of low-energy laser light that “wake up” the drainage cells, helping fluid flow more freely again.
There’s no cutting, no burning, and no downtime. You’ll rest comfortably in the exam chair, see a few flashes of light, and be done in about 5–10 minutes. Most patients head home right after and return to normal activities on the same day.
Numbing drops keep you 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.
Because SLT is non-invasive, there are no incisions or stitches, and most people return to normal activities right away.
Benefits of SLT
Lowers eye pressure without cutting or burning tissue
Often reduces or simplifies daily drop use
Short visit, no downtime for most patients
Repeatable if pressure begins to rise over time
Who Is a Candidate for SLT?
You may be a good candidate if you have open-angle glaucoma or ocular hypertension, if drops are not achieving your target pressure, if you experience side effects, if it is hard to keep up with a drop schedule, or if you want to reduce medication before considering surgery. Your West Texas Eye Associates doctor will confirm your diagnosis, measure eye pressure, and personalize your plan.
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 can occur for a few hours, then fades. 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.

Life After SLT
Most people resume normal activities right away. Regular eye exams remain important to confirm that pressure stays controlled and to decide if retreatment or additional therapy is needed. SLT can delay, and sometimes prevent, the need for more invasive glaucoma procedures.
