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.
