Abstract

Apparatus for instilling a medicament into an eye includes a housing having a longitudinal axis and a chamber disposed in the housing for containing a medicament. A nozzle is provided for instilling a dose of medicament into an eye and an actuator meters doses of medicament from the chamber to the nozzle and forces each metered dose through the nozzle upon axial displacement of the actuator along housing longitudinal axis. A spring causes the axial displacement of the actuator upon release of the spring from a compressed state. A collar disposed for rotation about the housing longitudinal axis is provided by compressing the spring by twisting the collar about the housing longitudinal axis and a trigger disposed in a housing is provided for releasing the compressed spring.
