Laser Trabeculoplasty (SLT / ALT) in Mumbai – Kurla BKC, Kalina & Bandra W

Selective Laser Trabeculoplasty (SLT) is a safe, quick, and highly effective office procedure that stimulates the eye's own drainage system to work more efficiently — often allowing patients to reduce or stop pressure-lowering drops. It is one of the most patient-friendly glaucoma treatments available.

What Is Laser Trabeculoplasty (SLT / ALT)?

SLT uses a low-energy laser directed at the trabecular meshwork (the eye's natural drainage tissue). It triggers a biological response that improves fluid outflow without damaging surrounding tissue. Unlike the older ALT (Argon Laser Trabeculoplasty), SLT can be repeated if the effect diminishes over time.

Who Is It For?

This procedure is generally suited to patients meeting the following criteria:

Early to moderate open-angle glaucoma
Patients struggling with eye drop compliance or side effects
As a first-line treatment alongside or instead of drops (supported by the LiGHT trial)
Those wishing to reduce medication burden

What Happens During the Procedure?

Each step is performed with precision and patient comfort in mind.

Step 1: Anaesthetic drops applied
Step 2: A special contact lens placed on the eye
Step 3: Laser applied to 180° or 360° of the drainage angle in a single session
Step 4: Procedure takes 5–10 minutes; patient goes home immediately after

Recovery & What to Expect

Minimal — mild redness or blurred vision for a few hours. The pressure-lowering effect develops over 4–6 weeks. A follow-up is scheduled at 6 weeks to assess the response.

Benefits

Patients choosing this procedure typically experience the following benefits:

No incision, no recovery period, no anaesthesia required beyond drops
Can reduce or eliminate the need for daily drops
Can be repeated if the effect wears off after a few years
Covered by many insurance plans

FAQFrequently Asked Questions

How effective is SLT?

Studies show SLT lowers IOP by 20–30% in responsive patients. The LiGHT trial showed SLT was as effective as drops as a first-line treatment for open-angle glaucoma.

Does SLT hurt?

No — patients may see brief flashes of light but feel no significant discomfort.

Will I definitely be able to stop my drops?

Not guaranteed — but a significant proportion of patients either reduce or stop their drops after a successful SLT. Dr. Mickey will advise based on your response at the 6-week review.
