1. A process for manufacturing an orbital implant, the process comprising:

  • shaping a mixture A into a substantially spherical body having a depression in its surface, with the depression having a size and shape of an orbital implant cap, wherein the mixture A comprises a bioactive material in particulate form, a binder, and a particulate pore forming agent;

    filling the depression with a mixture B to form a structure, wherein the mixture B comprises a bioactive material and a binder;

    consolidating the structure to form a spherical compact wherein the mixture B in the depression is coupled to the mixture A of the spherical body; and

    sintering the spherical compact to obtain a substantially spherical orbital implant comprising;

    an implant body comprising bioactive material of the mixture A and having macropores of at least 400 μ

    m as well as micropores smaller than 50 μ

    m, with some macropores being in communication with the outer surface of the implant body and with adjacent macropores being interconnected by openings and/or passageways so that open paths to the outer surface of the implant body are thereby provided, anda cap covering a portion of the implant body, the cap comprising bioactive material of the mixture B and having substantially no pores or only micropores smaller than 50 μ

    m, wherein the cap is thin relative to the diameter of the orbital implant, and wherein the cap is embedded in the implant body.
