An eye model for practicing vitreoretinal membrane peeling

A cost-effective, reusable practice eye model for epiretinal membrane peeling that uses easily obtained, commercially available materials was developed. A commercially available globe that is anatomically and optically similar to the human eye was modified by creating 2 ports that simulate superior sclerotomies. The model has a removable plastic anterior segment, which allows access to the posterior segment for practice membrane placement. Membranes were created on the macula by applying a coat of liquid skin bandage. Membrane peeling was performed under an ophthalmic operating microscope using a disposable flat vitrectomy lens. The basic skills required for membrane peeling can be demonstrated and acquired by practicing with this eye model. The practice eye model is expected to enhance the acquisition of skills required for epiretinal membrane peeling.
