ABSTRACT:
An orbital implant for use after evisceration or enucleation of an eye includes a core and at least one porous hydroxylapatite granule mounted on the core to promote incorporation of the implant into the fibro-vascular tissue of the eye. In one embodiment, a plurality of hydroxylapatite granules form a substantially spherical layer around a polymeric core. A synthetic covering surrounds the hydroxylapatite granules for attaching the muscles of the eye to the implant. Alternatively, a polymeric spherical core is provided with at least one cavity formed on an exterior surface, and at least one porous hydroxylapatite granule is mounted in the cavity. The implants may include an integral protrusion adapted to couple with an artificial eye. Further, a tubular, synthetic fabric can be used to cover the implants by gathering the tubular fabric at open ends and welding them closed in the vicinity of recesses formed in the outer surface of the core.
