Area of Science:

  • Ophthalmology
  • Optics
  • Medical Devices

Background:

  • The trabecular meshwork is crucial for aqueous humor outflow.
  • Enhanced visualization tools are needed for accurate diagnosis and treatment.
  • Current goniolens technology has limitations in magnification and resolution.

Purpose of the Study:

  • To introduce a new goniolens, the trabeculens, designed for enhanced visualization of the trabecular meshwork.
  • To evaluate the trabeculens's capabilities for diagnostic and therapeutic ophthalmic procedures.

Main Methods:

  • Development of the trabeculens, featuring a 30-diopter convex contact lens, hollow funnel, and four 62-degree mirrors.
  • Utilizing the trabeculens for magnified imaging of the trabecular meshwork.
  • Adapting the trabeculens with an indentor for laser trabeculoplasty.
  • Modifying the trabeculens with a 20-diopter button lens for laser iridectomy.

Main Results:

  • The trabeculens provides 1.6x magnification and enhanced resolution of the trabecular meshwork.
  • The device is adaptable for both laser trabeculoplasty and laser iridectomy.

Conclusions:

  • The trabeculens represents a significant advancement in goniolens technology.
  • This new lens improves visualization and procedural options for glaucoma management.
