How Does SLT Work?
SLT enhances the eye’s natural drainage system using targeted laser energy, prompting a healing response.
The laser selectively stimulates specific cells. The body’s immune response then improves drainage function over time.
Because SLT does not burn or scar tissue, it preserves the option for future treatments.
Who Can Benefit From SLT?
SLT is appropriate for many glaucoma patients wishing to improve eye pressure control.
SLT is often recommended early for open-angle glaucoma to limit the risk of progressive damage.
Those who have trouble using or tolerating eye drops may find SLT a welcome option.
Patients preferring to minimize their reliance on daily eye drops may benefit from SLT.
- Primary open-angle glaucoma
- Pigmentary glaucoma
- Pseudoexfoliation glaucoma
- Juvenile open-angle glaucoma
The SLT Procedure: What to Expect
SLT is a quick office procedure with minimal discomfort.
The treatment is done in our clinic, hospitalization is not needed.
There are no injections; numbing drops are used for comfort.
A lens with lubricating gel is placed on your eye to direct the laser.
Bright flashes and clicking sounds are common sensations during treatment.
The SLT treatment takes about 5–10 minutes per eye.
Slight blurring from the gel is expected but resolves quickly.
Most patients resume daily routines the next day.
Risks and Side Effects
SLT is very safe. As with any procedure, some side effects can occur.
- Mild discomfort and redness
- Temporary blurred vision
Occasionally, eye pressure may spike for hours to days, usually monitored and easily treated.
- Ocular inflammation (iritis)
- Very rarely: bleeding (hyphema) or corneal changes
SLT does not restore vision already lost to glaucoma; it helps prevent further progression.
Results and Long-term Outlook
SLT can successfully control intraocular pressure for many patients.
Approximately 70–85% of patients benefit from a significant drop in eye pressure after SLT.
The effects generally last 2–3 years, and treatment can be safely repeated if needed.
Some patients may still need eye drops or other interventions for optimum control.

Frequently Asked Questions

The full effect of SLT treatment may take 4 to 6 weeks to develop. Your eye pressure will be monitored closely during this period.
SLT is typically performed on one eye at a time so your doctor can monitor response and reduce the risk of complications. If both eyes need treatment, the procedures are usually scheduled a few weeks apart.
SLT can often reduce or occasionally eliminate the need for glaucoma drops, but not always permanently. Some people will still need medications to maintain their target pressure.
SLT is generally painless. Numbing drops are used, and most patients experience only slight pressure or mild irritation, with significant pain being very uncommon.
Patients should avoid rubbing their eyes and should use prescribed drops as directed. Most can return to normal activities immediately, but follow-up visits are important for pressure monitoring.
Yes. Because SLT does not cause tissue scarring, it can be safely repeated if eye pressure rises in the future.
