ABSTRACT:
An ocular drug delivery device includes a reservoir which holds medicine and is locatable outside the eye during drug delivery to a patient, and a conduit having one end coupled to the reservoir and a free end which is positionable within the fornix of the eye of a patient. Through gravity and/or capillary action, the medicine flows from the reservoir through the conduit and into the eye. The rate of delivery of the medicine to the eye may be adjusted according to the size and material of the conduit. According to a first embodiment, the reservoir is preferably made of an absorbent material and is provided with an impermeable backing which acts as a barrier between the medicine and facial skin of the patient. Preferably the backing has an edge to prevent medicine from rolling off the reservoir surface. The backing may also be provided with an adhesive for removably coupling the reservoir to the facial skin of the patient, particularly to an area adjacent the eye. According to a second embodiment, the reservoir is a hollow container and the conduit is a relatively narrow strip of an absorbent material running through a flexible tube. The reservoir is provided with an aperture through which medicine is provided to the reservoir, and preferably also includes an openable closure for alternately sealing the aperture and providing access to the reservoir.
