A coating for an orbital implant where the coating has an anterior portion having a different, longer term bioabsorbability than a posterior portion. This allows the implant to have a smooth surface for insertion and to provide reduced irritation to neighboring tissues, to help prevent exposure of the porous core of the implant, and to provide a stable anchorment for extraocular muscles, but which also encourages rapid fibrovascular ingrowth. The coating is marked with a visual indicator to facilitate proper orientation. Shell materials are further selected to allow for sterile packaging, the securing of therapeutic agents thereon, and to provide adequately strong securing of the coating to the core. Apertures are formed through the coating to enhance fluid flow to and from the core, and to provide exposure of the surface of the core to extraocular muscles, and for sutures. The apertures are sized and shaped to reduce irritating surface contact with orbital tissues.
