A cadaveric eye model for practicing anterior and posterior segment surgeries

Ophthalmology. 1995 Dec;102(12):1932-5. doi: 10.1016/s0161-6420(95)30773-7.

Abstract

Objective: To develop a simple and effective model for practicing anterior and posterior segment surgeries.

Design: A Lander wide-field keratoprosthesis was used as an artificial cornea in human cadaver eyes.

Results: The keratoprosthesis provided a tight seal which maintained the anterior chamber. Continuous curvilinear capsulorrhexis, hydrodissection, and phacoemulsification of the cadaveric lens followed by insertion of a foldable intraocular lens into the capsular bag were performed through a standard three-planed scleral tunnel incision. Pars plana vitrectomy, using the standard three-port approach, was performed. Panretinal photocoagulation was performed using a slit-lamp laser delivery system and a Rodenstock lens.

Conclusions: This eye model very closely simulates the tactile behavior of a living eye and may be useful as a realistic practice and teaching platform for a wide variety of anterior and posterior segment surgical procedures, including laser photocoagulation.
