Abstract

An ophthalmic device including a cannula having a cannula distal end, a lumen, and one or more orifices coupled to the lumen is provided. The cannula is configured to deliver a fluid. A sleeve is disposed around the cannula and has a sleeve distal end. A handle is coupled to the sleeve and the cannula, the handle having an actuator. An internal mechanism is coupled to the actuator and configured to retract the sleeve relative to the cannula. The internal mechanism includes a follower fixedly coupled to the sleeve and moveable between distal and proximal positions, and a release member movable between an activated position and a release position. The release member is coupled to the actuator and configured to release a force that urges the follower from the distal position to the proximal position when the release member moves from the activated position to the release position.
