Claim 0:
1. An ophthalmic device comprising:
a cannula having a cannula distal end, a lumen, and one or more orifices coupled to the lumen, the cannula configured to deliver a fluid;
a sleeve disposed around the cannula and having a sleeve distal end;
a handle coupled to the sleeve and the cannula at a handle distal end, the handle having an actuator; and
an internal mechanism coupled to the actuator and configured to pump the fluid, the internal mechanism comprising:
an inlet port disposed on a handle proximal end;
a drive member coupled to the actuator; and
a plunger coupled to the drive member, wherein rotation of the drive member is configured to provide a force that moves the plunger in a distal direction along a longitudinal axis of the handle when the actuator moves from an un-pressed position to a pressed position, the movement of the plunger causing the fluid to move distally through the handle and the cannula, and a portion of the fluid to exit the one or more orifices,

wherein the ophthalmic device is configured to retain a volume of fluid and to be prevented from being re-primed after a predetermined number of actuator presses, wherein the retained volume of fluid is dispensed over an additional number of actuator pushes.
