1. A device for delivering a volume of fluid to an eye, comprising:
a housing;
a fluid ejector located within the housing, the fluid ejector having a vibrating element with a plurality of openings and a central axis, the vibrating element having a fluid side and a delivery side with the plurality of openings extending from the fluid side to the delivery side, the fluid ejector ejecting fluid from the fluid side through the plurality of openings to the delivery side when the vibrating element is vibrated;
an enclosure positioned adjacent the fluid side the vibrating element, the enclosure and the vibrating element forming a chamber, wherein the enclosure includes a wall having a lip positioned adjacent the fluid side of the vibrating element, the lip extending around the plurality of openings, the enclosure and the vibrating element together defining the chamber which holds a volume of the fluid to be dispensed; and
a pump having a first part and a second part, the first part reciprocates between a stored position to a forward stroke position at a greatest displacement and back from the forward stroke position to the stored position each cycle, the pump also having a second pump part which also reciprocates between a stored position to a forward stroke position at a maximum displacement and back to the stored position each cycle.
