Apparatus for instilling a medicament into an eye includes a rigid housing for containing a reservoir of medicament and a nozzle for instilling a dose of the medicament into an eye. A displacement pump, sealing a front end of the rigid housing and in fluid communication with the reservoir, provides for metering doses of medicament from the reservoir to the nozzle and for forcing each metered dose through the nozzle. A stopper, slidably disposed within a rear end of the rigid housing, provides for gradually decreasing the housing volume containing the medicament reservoir. A diaphragm provides for accommodating transient decreases in the volume containing the medicament reservoir during metering of doses therefrom by the displacement pump.
