For many glaucoma patients, the path forward isn't more eye drops — it's a quick, in-office laser procedure that can lower eye pressure for years at a time.

What Is SLT?

Selective Laser Trabeculoplasty (SLT) is a laser treatment that targets the eye's drainage system (the trabecular meshwork) to help fluid drain more efficiently, lowering intraocular pressure. It's called "selective" because it targets specific cells without damaging surrounding tissue, which means it can typically be repeated later if needed.

Who It's For

SLT is commonly used for open-angle glaucoma and can be used as a first-line treatment (instead of starting with drops), as an add-on when drops aren't fully controlling pressure, or as an alternative for patients who struggle with the cost, side effects, or consistency of daily eye drops.

What the Procedure Is Like

SLT is performed in the office and typically takes just a few minutes per eye:

• Numbing drops are applied
• A special lens is placed on the eye to help focus the laser
• The laser is applied to the drainage angle in a series of quick pulses
• Most patients feel little to no discomfort during the procedure

Recovery and Results

There's generally no downtime — many patients resume normal activities the same day, aside from a follow-up visit to check eye pressure. It can take a few weeks for the full pressure-lowering effect to show up, and not every patient responds the same way. When effective, results commonly last one to five years, and the treatment can often be repeated.

Benefits Compared to Drops

• No daily adherence required
• No systemic side effects like drops can sometimes cause
• Can reduce (though not always eliminate) the need for medication

The Bottom Line

SLT isn't right for every type of glaucoma or every patient, but for many, it offers real pressure control without adding another bottle to the medicine cabinet. If drops have been a struggle, it's worth asking whether you're a candidate.
