Selective Laser Trabeculoplasty (SLT) is a revolutionary treatment for lowering eye pressure associated with glaucoma. This gentle laser procedure enhances the eye's natural drainage system, making it a vital option for preserving your vision.
Selective Laser Trabeculoplasty, or SLT, is a safe, effective, and gentle laser procedure performed in your eye doctor's office to lower eye pressure associated with glaucoma.
This section explains what glaucoma is and how SLT serves as a key treatment option to protect your vision from damage caused by high eye pressure.
Glaucoma is a disease that damages the eye's optic nerve, often caused by high fluid pressure inside the eye. If left untreated, this pressure can lead to irreversible vision loss, starting with peripheral vision.
SLT is a type of laser therapy that enhances your eye's natural drainage system to lower internal pressure. It uses short, gentle pulses of low-energy light to target specific cells, leaving surrounding tissues unharmed.
SLT is used to lower intraocular pressure (IOP) and reduce the risk of optic nerve damage. It is often recommended as a first-line treatment, an alternative for those who have trouble with eye drops, or as an additional measure to control pressure.
No, SLT has been an FDA-approved treatment for over two decades and is considered a very safe and established procedure. It evolved from an older laser treatment called Argon Laser Trabeculoplasty (ALT) but is gentler and can be repeated.
SLT is a versatile treatment, but it is most effective for patients with specific types of glaucoma or high eye pressure. Your doctor will determine if it is the right choice for you.
This is the most common form of glaucoma and the primary indication for SLT. It is caused by the slow clogging of the eye's drainage canals, and SLT works well to improve fluid outflow.
Individuals with high eye pressure but no optic nerve damage yet may be offered SLT as a preventive measure to delay or stop the onset of glaucoma.
SLT is an excellent option for those who find a daily eye drop routine challenging due to side effects, cost, or difficulty administering the drops correctly.
SLT is not suitable for everyone. It is generally not used for patients with angle-closure glaucoma, significant scarring in the drainage angle, or active inflammation in the eye.
The procedure uses advanced laser technology to trigger a natural healing response within the eye, improving its ability to drain fluid and thereby lowering pressure.
Using a special lens, the laser is precisely aimed at the trabecular meshwork, which is the eye's natural drainage structure. This area is responsible for draining fluid from the eye.
The laser applies low-energy light to pigmented cells in the meshwork. This gentle stimulation triggers the body’s natural mechanisms to improve fluid flow without creating scar tissue.
As the drainage system begins to function more efficiently, the pressure inside the eye is reduced. Most patients see a 20 to 30 percent drop in eye pressure within one to three months.
The entire procedure is quick, performed in the office, and involves minimal discomfort. Knowing what to expect can help you feel more comfortable on the day of your treatment.
Your doctor will explain the procedure and answer your questions. Numbing anesthetic drops will be placed in your eye to ensure comfort. You may also receive an eye drop to prevent a temporary pressure spike after the procedure.
You will be seated at a machine similar to the one used for regular eye exams. A special lens will be placed on your eye to help focus the laser. You will see a flashing light and may hear a clicking sound as the laser delivers quick, quiet pulses of light.
Your vision may be blurry for a few hours. Your eye pressure will be checked about one hour after the procedure. It is important to follow your doctor's instructions for post-treatment care.
SLT is considered very safe, and the risk of serious complications is low. Most side effects are mild, temporary, and resolve on their own.
The most common side effects include mild eye redness, light sensitivity, and a feeling of scratchiness. Some patients experience a brief, temporary spike in eye pressure that is monitored and managed by your doctor.
In rare cases, prolonged inflammation or a significant, lasting increase in eye pressure can occur. These complications are uncommon and can typically be managed with medication.
Your doctor minimizes risks by carefully selecting candidates and providing detailed pre- and post-treatment instructions. Attending all follow-up appointments is crucial for monitoring your eye's response.
If you’re experiencing high eye pressure or have been diagnosed with glaucoma, it’s crucial to speak with an eye care professional. Find a top optometrist or ophthalmologist near you through Specialty Vision to discuss SLT and your other treatment options.
