Selective Laser Trabeculoplasty (SLT) in the Bay Area – A Modern Treatment for Glaucoma
Glaucoma is a condition where increased eye pressure damages the optic nerve, often leading to gradual loss of peripheral vision. This occurs when fluid inside the eye (aqueous humor) does not drain properly through the eye’s natural drainage system, known as the trabecular meshwork.
If left untreated, elevated eye pressure can eventually affect central vision and lead to permanent vision loss.
How SLT Lowers Eye Pressure
Selective Laser Trabeculoplasty (SLT) is an advanced, in-office laser treatment used to lower intraocular pressure in patients with open-angle glaucoma.
Rather than relying on medications, SLT:
- Uses low-energy laser pulses
- Targets specific melanin-containing cells in the trabecular meshwork
- Stimulates the body’s natural drainage system
This improves fluid outflow from the eye and helps reduce pressure without damaging surrounding tissue.
Selective Laser Trabeculoplasty vs Older Laser Treatments
SLT is a newer generation treatment compared to Argon Laser Trabeculoplasty (ALT).
Unlike ALT, which can cause scarring and tissue damage, SLT:
- Is more selective in how it targets cells
- Preserves surrounding healthy tissue
- Can be repeated if needed
This makes SLT a safer and more flexible option for long-term glaucoma management.
Who Is a Candidate for SLT
Selective Laser Trabeculoplasty may be recommended for patients who:
- Have been diagnosed with open-angle glaucoma
- Need better control of eye pressure
- Prefer to reduce or avoid long-term use of eye drops
- Have not responded adequately to medications
It can be used as a first-line treatment or in combination with medications, depending on the individual case.
What to Expect During the Procedure
SLT is performed in the office and typically takes only a few minutes.
During the procedure:
- Numbing eye drops are applied (no injections required)
- A special lens is placed on the eye to guide the laser
- You may see brief flashes of light during treatment
- No pain is typically felt
Because it is not performed in a surgical center, patients can return home immediately after treatment.
Recovery and Follow-Up
After Selective Laser Trabeculoplasty:
- Most patients resume normal activities the same day
- Eye pressure is checked within 1–2 weeks
- Full pressure-lowering effect may take several weeks (up to 6–8 weeks)
In some cases, mild eye drops may be used temporarily for comfort.
How Effective Is SLT?
SLT can significantly reduce eye pressure and may:
- Delay or eliminate the need for medications
- Reduce the number of drops required
- Be repeated if the effect decreases over time
While results vary, it is considered a safe and effective long-term treatment option for many patients.
Long-Term Considerations
The effect of SLT may gradually diminish over several years, but the procedure can often be repeated without harm.
Serious complications are rare, especially when performed by experienced glaucoma specialists.
