Abstract:
1. A method for forming an ocular drug delivery device comprising the steps of: forming a drug core containing an active agent; disposing an amount of a first material in a first mold part; placing the drug core within the first mold part such that the drug release surface is in contact with the first material, wherein the drug core has a barrier disposed on all surfaces thereof except for a drug release surface thereof which is left free of the barrier, the barrier being formed of a material through which the active agent is prevented from diffusing; at least partially adhering the drug core to the first material; disposing an amount of a second material between the first mold part and an opposing second mold part such that the second material surrounds the drug core and fills a mold cavity between the first and second mold parts, wherein the second polymeric material surrounds and is contact with the barrier of the drug core but is free of contact with the drug release surface of the drug core; and polymerizing the second material to form a body of the ocular drug delivery device which is then removed from the first and second mold parts, the ocular drug delivery device body including a drug release membrane, formed of the first material, that covers the drug release surface of the drug core and is configured to permit drug to pass therethrough over a period of time.
