ABSTRACT:
A surgical instrument to facilitate the insertion and allow better control of the superior haptic of an intraocular lens into the capsular bag of the eye. The instrument includes a hollow cannula with a beveled distal tip and a tapered slot extending proximally from the distal tip of the cannula. A stylet slides freely within the cannula and has a distal tip beveled at an angle corresponding to the bevel of the distal tip of the cannula. A handle is provided for supporting the cannula and the stylet and includes a mechanism for advancing the stylet distally to align the beveled distal tips of the cannula and the stylus to form a plane which resolves the forces exerted by the resilient haptic in a direction which urges the haptic into the capsular bag.
