Abstract
The present invention provides an ophthalmic fluid delivery device adapted to deliver an ophthalmic fluid in the form of a mist to an ocular region of a patient. The ophthalmic fluid delivery device comprises a nozzle defining an aperture through which the ophthalmic fluid can flow and at least one shutter positioned proximate to the aperture of the nozzle. The shutter is mounted for movement with respect to the aperture of the nozzle between an open position permitting flow of the ophthalmic fluid through the aperture of the nozzle and a closed position at least partially covering the aperture. A shutter actuator is positioned proximate to the shutter. The shutter actuator is mounted for movement with respect to the nozzle, and the shutter actuator is coupled to the shutter such that the movement of the shutter actuator moves the shutter between the open position and the closed position.
