Study summary

This study compares two FDA-approved laser treatments for glaucoma: Direct Selective Laser Trabeculoplasty (DSLT) and Selective Laser Trabeculoplasty (SLT). Both procedures aim to lower eye pressure and prevent vision loss. DSLT is a newer, non-contact technique that may improve comfort and efficiency. Participants will be randomly assigned to receive either DSLT or SLT and followed for 12 months to assess eye pressure, safety, and treatment outcomes.

Study arms

  • Experimental
    Direct Selective Laser Trabeculoplasty

    This arm is going to receive the Direct SLT treatment

    Device: Direct Selective laser Trabeculoplasty

  • Active comparator
    Traditional Selective Laser Trabeculoplasty

    This arm is going to receive the Traditional SLT treatment which will act as a control for the experimental arm. Note that both lasers are Standard of Care (SOC) and FDA approved

    Device: Direct Selective laser Trabeculoplasty

Interventions

  • DeviceDirect Selective laser Trabeculoplasty

    The Direct Selective Laser Trabeculoplasty is a non-contact laser designed to manage IOP in patients with glaucoma. The traditional SLT required a gonioscopy lens to be placed over the patient's eyes to direct the laser towards the trabecular meshwork.
