A pupil expander insertion system for eye surgery includes a pupil expander insertion tool (10) and an iris retracting glide (80). The insertion tool (10) includes a housing (12) having forward and rearward ends (24, 26), a hollow chamber in which a piston (16) is axially movable, and an aperture formed in the forward end that communicates with the hollow chamber. A retractable blade (22) for holding a pupil expander (32) in an elongated condition is journaled within the aperture and connected to the piston (16) for longitudinal movement therewith. The forward end of the blade (22) has a slot extending rearwardly, defining a pair of tines (44, 46) wherebetween the expander can be slidably inserted. A stationary hollow spatula (20) surrounds the blade in the retracted position, contacting the pupil expander (32) to slidingly urge it off the retracting blade (22). The glide (80) has an elongated tongue (82) with a folded tab (88) on one end slidably inserted through a slot means (96) in the other end. |
