Excimer laser ablation can create an open pathway between the anterior chamber and Schlemm

Area of Science:

  • Ophthalmology
  • Surgical Innovation
  • Laser Medicine

Context:

  • Glaucoma treatment often involves improving aqueous humor outflow.
  • Current surgical methods for glaucoma have limitations.
  • Trabecular meshwork ablation offers a potential new approach.

Purpose:

  • To investigate the feasibility of using excimer laser ablation to create an anterior chamber to Schlemm's canal pathway.
  • To assess the efficacy and safety of this laser-based trabecular meshwork ablation technique.

Summary:

  • Excimer laser ablation of the trabecular meshwork (AT) was performed in enucleated eyes.
  • Direct pathways were created between the anterior chamber and Schlemm's canal using specific laser parameters (0.3-1.5 mJ, 248/308 nm).
  • Histologic examination confirmed complete trabecular meshwork removal with minimal thermal damage, and demonstrated potential for cyclodialysis and iridectomy.

Impact:

  • This technique offers a precise and minimally invasive method for glaucoma surgery.
  • Successful creation of a direct pathway could enhance aqueous humor outflow.
  • Potential for simplified glaucoma surgical procedures with accurate targeting.
