Claim:
An implantable drug delivery device, comprising: (a) a casing defining an inner volume, and comprising an outer surface, the outer surface comprising an eye-contacting surface, wherein the eye-contacting surface comprises a shape complementary to an outer surface of a mammalian eye, and wherein when implanted, the eye-contacting surface substantially conforms to the outer surface of a mammalian eye, the eye-contacting surface defining an aperture port passing therethrough, wherein the inner volume is in fluid flow communication with the outside of the casing; (b) a reservoir member comprising a drum disposed within the casing, wherein the reservoir member defines a cavity for receiving the drug; and (c) a seal attached to the reservoir member for sealing drug within the cavity, which when punctured permits drug disposed within the cavity to be released into the inner volume and to exit the casing via the aperture port defined in the eye-contacting surface.
