Pig eye trabeculectomy - a wet-lab teaching model

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.
