Abstract
Abstract A system for controlling a plurality of ophthalmic microsurgical instruments is disclosed. Particularly, the present invention includes a handpiece for activating a surgical instrument (i.e., such as scissors) connected to the handpiece. The handpiece includes a housing and a linear activator operatively retained within the housing. A nosepiece is mounted to one end of the housing and is adapted for correction of a linearly actuated surgical instrument. The nosepiece is fixed to the linear activator in a preselected calibrated position relative to the longitudinal axis of the linear actuator.
