Pattern Scanning Laser Trabeculoplasty

The scanning technology and precision of PASCAL systems uses a minimally-damaging laser delivery modality for laser trabeculoplasty. Pattern scanning laser trabeculoplasty (PSLT) provides rapid, precise, and minimally traumatic (sub-visible) computer-guided treatment with exact placing of the patterns. The patterns readily align to the curve of the trabecular meshwork, allowing faster and easier applications compared to other laser modalities. Physicians can now use their PASCAL® Streamline™, Synthesis™ and TwinStar™ lasers for trabeculoplasty for open angle glaucoma; along with other conventional procedures.


Key Features
  • Increased Functionality - The PASCAL laser now opens more options for physician use with pattern-specific trabeculoplasty for open angle glaucoma.
  • Precise alignment – New pattern developed specifically for open angle glaucoma results in precise alignment to the trabecular meshwork. Spacing and spot placement is accurate and consistent.
  • Lower intraocular pressure – Clinical studies show an IOP reduction of 24% in 6 months ¹
  • Minimally traumatic / sub-visible procedure – Laser applications are delivered below levels of conventional photocoagulation. As a result, cellular healing response without scarring damage is achieved².
  • Less Pain compared to SLT – Greater patient comfort and less pain over SLT. ²
  • Reduced treatment time compared to SLT – Shorter duration of laser treatment for PSLT compared to SLT²


    Availability: PASCAL PSLT is an optional software that can be installed in Streamline, Synthesis and TwinStar lasers with 532 (green) and 577 (yellow) Nm wavelength. PSLT is not available in 638Nm (red) wavelength.
