US Patent 10360815 Simulating eye surgery

A reusable surgical model of the eye has mating anterior and posterior segments. The posterior segment has structures corresponding to those of the eye, including a hollow globe and an image of the fundus positioned upon an interior, posterior portion of the globe. A mating connector is peripherally formed about an open end of the globe. The anterior segment includes structures corresponding to those of the eye, including a pars plana, an opening in a region corresponding to an iris, and a lens positionable within the opening. The anterior segment has a peripheral connector which mates with that of the posterior segment. The lens is removably connected to the anterior segment, and has a focal length corresponding to a natural eye. A coating is applied to the fundus to enable simulation of a membrane peeling procedure, and the globe is fillable with a vitreous substitute.
