Anterior capsulotomy device and procedure

摘要

A device for performing an anterior capsulotomy procedure has an elongate tubular member with an opening formed near the distal end thereof. A cutter is movably disposed within the tubular member and has a blade formed thereon. A vacuum port is in fluid communication with the lumen of the tubular member. An actuator effects movement of the cutter so as to move the blade across the opening. The opening is configured to draw in a portion of a capsule when a vacuum is applied to the vacuum port such that the cutter forms a generally circular cut of a predetermined size in the capsule when the actuator is actuated.
