Selective Laser Trabeculoplasty (SLT)

What is Selective Laser Trabeculoplasty (SLT)?

Selective Laser Trabeculoplasty (SLT) is a laser-based treatment for open-angle glaucoma, designed to reduce intraocular pressure (IOP). The procedure is typically performed in an outpatient ophthalmic setting, is minimally invasive, and usually takes less than 5 minutes.

How is the Procedure Performed?

Selective Laser Trabeculoplasty (SLT) uses a low-energy laser to precisely target pigmented cells in the trabecular meshwork of the eye. The laser stimulates these cells, initiating the body's natural healing response, which helps regenerate healthy cells within the meshwork. This process enhances the drainage of aqueous humor, effectively lowering intraocular pressure (IOP). SLT is highly selective, affecting only the pigmented cells without damaging other structures of the eye.

Treatment Process

Prior to the procedure, the patient is given pupil constricting and local anesthetic eye drops. During the procedure, the ophthalmologist uses a specialized lens to precisely direct the laser to the trabecular meshwork. The procedure is quick, typically lasting just a few minutes. Post-treatment, anti-inflammatory eye drops are prescribed to aid in recovery.

How SLT Effectively Lowers Intraocular Pressure (IOP)?

Selective Laser Trabeculoplasty (SLT) has a success rate of approximately 75%, with effects lasting 2 to 3 years. Due to its non-thermal and non-invasive nature, SLT can be repeated if necessary. For patients who do not achieve sufficient IOP reduction, pharmacological treatments remain a viable alternative.
