Abstract
A ring for dilating a pupil during an ophthalmic procedure includes a series of spaced supports for engaging an iris perimeter. The supports are plate elements which form an open pocket directed outwardly for engaging the iris. The sides of the ring form a primary plane, and the plates are located in respective planes above and below the primary plane. The outer periphery of the top and bottom plates forms a lip feature which is the opening to the pocket which retains the iris.
