Zusammenfassung:	A method for forming an ocular drug delivery device includes the steps of: (1) forming a drug core containing an active agent, wherein the drug core has a barrier disposed all surfaces thereof except for a drug release surface which is left free of the barrier; (2) forming a drug release membrane over the drug release surface; and (3) forming the remaining portion of the device body by an overcast (overmold) process. L'invention concerne un procédé d'assemblage d'un dispositif d'administration de médicaments oculaires, comprenant les étapes suivantes : (1) l'élaboration d'une base médicamenteuse contenant un agent actif, cette base médicamenteuse étant recouverte d'une barrière sur toute sa surface, à l'exception de la surface consacrée à la libération de médicaments, qui n'est pas recouverte avec la barrière ; (2) l'élaboration d'une membrane contrôlant la libération de médicaments, située sur la surface de libération de médicaments ; et (3) l'élaboration de la partie restante du corps du dispositif au moyen d'un processus de recouvrement (surmoulage).
