Abstract
An apparatus for providing an adjustable aperture used in the practice of simulated artifical intraocular lens insertion comprising; a flexible diaphragm with a circular aperture therethrough, a cylindrical diaphragm mount for supporting the diaphragm, a diaphragm control member within the mount, and means for moving the control member against the diaphragm, thereby stretching the diaphragm and expanding the size of the circular diaphragm aperture. The size of the aperture is increased or reduced in order to simulate the pupil of the eye in various stages of dilation. The flexible diaphragm member is used to simulate the iris, so that an artificial intraocular lens may be inserted through the circular aperture and mounted on the flexible diaphragm member, thereby simulating the mounting of such a lens to the iris of the human eye.
