Area of Science:

  • Ophthalmology
  • Surgical Education

Background:

  • Trabeculectomy is a crucial surgical procedure for managing glaucoma.
  • Increasing efficacy of medical treatments has led to fewer trabeculectomy procedures being performed.
  • This reduction limits essential surgical training opportunities for ophthalmologists.

Purpose of the Study:

  • To describe a novel teaching model for trabeculectomy.
  • The model utilizes formalin-preserved pig eyes for simulation.

Main Methods:

  • The teaching model allows practice of critical trabeculectomy techniques.
  • Key skills include creating a fornix-based conjunctival flap.
  • Surgical simulation involves constructing a scleral flap with releasable sutures and ensuring watertight conjunctival closure.

Main Results:

  • Wet laboratory practice significantly improves exposure to necessary surgical skills.
  • Trainee surgeons can refine tissue handling crucial for successful trabeculectomy.

Conclusions:

  • The described pig eye model provides valuable hands-on training for trabeculectomy.
  • Wet laboratories are vital for ophthalmology training programs.
  • This approach compensates for reduced clinical exposure to trabeculectomy surgery.
