This study presents a novel method for preparing human cadaveric eyes for ophthalmic surgical training. This model allows direct visualization of the anterior chamber angle for practicing trabecular meshwork surgery.

Area of Science:

  • Ophthalmology
  • Surgical Education
  • Anatomy

Background:

  • Ophthalmic surgical training requires effective practice models.
  • Current models may have limitations regarding infection risk and reusability.

Purpose of the Study:

  • To describe a method for preparing human donor cadaveric eyes for practicing trabecular meshwork surgery.
  • To adapt this model for both fresh and formalin-fixed eyes.

Main Methods:

  • Preparation of human donor cadaveric eyes.
  • Direct visualization of the anterior chamber angle.
  • Adaptation for fresh and formalin-fixed eyes.

Main Results:

  • The model allows for direct visualization of the anterior chamber angle.

Trabecular Meshwork Response to Pressure Elevation in the Living Human Eye

Published on: June 20, 2015

  • Formalin-fixed eyes reduce infection risk, allow indefinite storage, and enable reuse.
  • The model was applied to ab interno trabeculectomy using the Trabectome system.

    • Conclusions:

    • This model provides a valuable tool for ophthalmic surgical training.
    • It enhances safety and efficiency in practicing trabecular meshwork surgery.
    • The technique is applicable for treating open-angle glaucoma.
