Selective Laser Trabeculoplasty

What is Laser Therapy?

SLT or Selective Laser Trabeculoplasty is a clinically proven procedure that can safely and effectively lower intraocular pressure (IOP).

How does SLT Work?

Selective Laser Trabeculoplasty only targets pigmented tissue cells within the eye. Laser energy is absorbed only by those targeted tissue cells, preserving and protecting surrounding tissue. This laser energy stimulates the natural healing response within the eye, resulting in greater fluid outflow and lower eye pressure.

What Can I Expect During An SLT Treatment?

SLT is an outpatient procedure, usually performed in an office. Anesthetic eye drops are used to prepare the eye and treatment takes place in a standard exam chair. The SLT laser is attached to a slit lamp (the lamp used for eye exams). A contact lens is then used to hold your eye open and focus the laser energy onto the drainage area of your eye. Next, laser energy is released at the edge of your pupil. The procedure takes just a few minutes to complete. Most patients report a slight pinch during the procedure but not pain.

What Can I Expect After SLT Treatment?

Your vision may be blurry for several hours, possibly up to 24 hours. Generally, the eye is mildly irritated for 1-2 days. Dr. Surti may prescribe eye drops for the first few days to help treat any irritation or inflammation. You will schedule a follow-up appointment for approximately four weeks after treatment to check your eye pressure. DO NOT stop taking medications, including your prescription glaucoma drops, unless advised by Dr. Surti.

How Many Treatment Are Required?

Unlike daily eye drops, SLT therapy is administered just once in a simple, fast, in-office procedure. Therapy has been shown to be effective for up to two years. Because glaucoma is a chronic disease, follow-up appointments with Dr. Surti are important. SLT can be safely performed on patients who have not found success with ALT surgery or who have been on glaucoma medication therapy. SLT can also be safely repeated on patients. As with any medical procedure, results may vary.

What are the Side Effects?

Unlike many glaucoma medications, there are no reported incidences of allergic reactions or systemic side effects with SLT. Complications are rare, but inflammation, a temporary increase in eye pressure, blurred vision, headache, red eye or eye pain have been reported.
