A cartridge for actuating a piston-like or accordion-like dispenser-vial for applying medicament to an eye. The cartridge includes a housing for holding the dispenser-vial and a telescoping cylinder for compressing the dispenser-vial in the longitudinal direction to actuate the vial. The cartridge includes a locking mechanism for locking the telescoping cylinder to restrict its movement and a trigger mechanism for releasing the cylinder from the locked position so that a drop is released from the dispenser. The housing includes a finger for engaging the lower eyelid and exposing the conjunctival cul de sac.

[ What is claimed is:] [9.] A cartridge in combination with a dispenser for applying medicament to an eye, the dispenser comprising: a container holding a volume of fluid; a first dosage cavity forming member and a second dosage cavity forming member, the second member being movable between: a first position, in which the first member and the second member together define a cavity which is in fluid communication with the container; a second position, in which the first member and the second member together define a cavity having a certain predetermined volume and in which the cavity is not in fluid communication with the container; and a third position in which the volume of the cavity is less than the volume of the cavity in the second position and in which the cavity is not in fluid communication with the container; a means for biasing the second dosage cavity forming member to the third position; and a nozzle which is in fluid communication with the cavity, wherein a dosage of fluid in the cavity is forced through the nozzle and out of the apparatus upon movement of the second member from the first position or the second position to the third position under the action of the biasing means, and wherein the second member is selectively movable from the third position back to the first position to draw fluid from the container into the cavity after each dosage of fluid is forced through the nozzle out of the apparatus, the cartridge comprising:a housing which houses the dispenser, the housing having an opening which exposes the nozzle of the dispenser;a pushable member coupled to said housing and being slidable relative to said housing and pushable against a compressible portion of said dispenser, the pushable member being slidable between: a first position wherein the second dosage cavity forming member is in its first position; a second position wherein the second cavity forming member of the dispenser is in its second position; and a third position wherein the second cavity forming member of the dispenser is in its third position, said pushable member being selectively and releasably lockable with respect to the housing in either the first position or the second position so as to releasably lock the second dosage cavity forming member in a corresponding position; anda means for biasing said pushable member and the second dosage cavity forming member toward the third position, said biasing means forcing said pushable member to move from said first or second position to said third position when said pushable member is unlocked relative to said housing in said first or second position. .Iaddend..Iadd.
