Abstract: The present disclosure generally relates to microsurgical instruments having variable stiffness such as microsurgical instruments having variable stiffness for ophthalmic surgical procedures. In one embodiment, a surgical instrument includes a probe and a stiffener assembly. The stiffener assembly further includes a stiffener formed of a hollow tubular member substantially surrounding at least a portion of a length of the probe. Actuation of the stiffener along the length of the probe adjusts the stiffness of the probe, thus providing a user better control of the surgical instrument.

Abstract: The present disclosure generally relates to surgical instruments having variable stiffness, and more particularly, surgical instruments having variable stiffness for ophthalmic surgical procedures. In certain embodiments, a surgical instrument includes a base unit, a probe, a stiffener, and an actuation mechanism. The stiffener is formed of a hollow tubular member substantially surrounding at least a portion of a length of the probe. The actuation mechanism is configured to actuate the stiffener along the length of the probe and adjust the stiffness of the probe, thus providing a user better control of the surgical instrument. The actuation mechanism includes a stiffener biasing device configured to apply a first biasing force against the stiffener in the distal direction and, in some embodiments, a control member configured to lock the stiffener in a position along the length of the probe.

Abstract: Systems, methods, and devices for inserting an intraocular lens (IOL) into an eye may be provided. An example IOL injector device may include a housing, wherein the housing comprises a first end and a second end. The IOL injector device further may include a battery and a plunger disposed within the housing. The IOL injector device further may include a motor powered by the battery and configured to cause the plunger to translate in the housing. The IOL injector device further may include a user interface disposed on the housing, wherein the user interface receives user input to start translation of the plunger.
