SLT FAQs

What is SLT laser therapy?
SLT, or Selective Laser Trabeculoplasty, is a clinically proven procedure that safely and effectively lowers intraocular pressure (IOP).

How does SLT laser therapy work?
Using an advanced laser system, pigmented tissue cells within the eye are selectively targeted. 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 and results in greater fluid outflow, which in turn lowers eye pressure.

What can I expect during the SLT treatment?
SLT is an outpatient procedure performed in our ambulatory surgery center. Eye drops are used to numb the eye and treatment takes place in a standard exam chair with a slit lamp like the one used to examine your eye. The SLT laser is attached to the slit lamp. A contact lens is then used to hold your eye open and focus the laser energy onto the drainage area of your eye. Laser energy is released multiple times at the edge of your pupil and the procedure will take just a few minutes to complete. Most patients do not report pain during or after the treatment.

Is SLT reimbursed by Medicare?
Yes, SLT is reimbursed by Medicare and most insurance providers, potentially saving you thousands of dollars in non-reimbursed prescription medication costs.

What can I expect after the 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. Your doctor will prescribe eye drops for the first few days to help treat any irritation or inflammation. Do NOT stop using your regular glaucoma drops until advised by your doctor.  A follow-up appointment will be recommended.

How many treatments are required?
As with any medical procedure, results may vary. However, unlike daily eye drops, SLT therapy is administered just once in a simple, fast, in-office procedure. Because glaucoma is a chronic disease, follow-up appointments with your eye care specialist are important. SLT can be safely performed on patients who have failed other laser surgeries or who have been on glaucoma medication therapy. SLT may be safely repeated if needed.

What are the side effects with SLT?
Unlike many glaucoma medications, there are no reported incidences of allergic reactions or systemic side-effects with SLT. Complications are rare, but may include inflammation, a temporary increase in eye pressure, blurred vision, headache, conjunctivitis, or eye pain.

Will treatment be done on both eyes at the same time?
No, only one eye is typically done at a time per the written policy of our ambulatory surgery center and the prevailing medical standard of care.

Will I be able to drive home following the treatment?
Yes
