Pig eye trabeculectomy-a wet-lab teaching model

Abstract

Purpose: A teaching model for trabeculectomy is described using pig eyes prepared in formalin.

Method: The model enables trainee surgeons to practice various aspects of tissue handling required for successful trabeculectomy including the construction of a fornix-based conjunctival flap, scleral flap with buried releasable sutures, and water-tight conjunctival closure.

Results: Exposure to the necessary skills required to perform trabeculectomy surgery can be improved by the use of wet laboratory practice.

Conclusions: Trabeculectomy surgery experience is becoming more limited as fewer procedures are being performed due to the efficacy of recent medications. Wet laboratories will become an increasingly important aspect of a comprehensive ophthalmology training programme.
