Highly satisfactory orbital implants comprising granular hydroxyapatite and spheres of porous, low density hydroxyapatite are described. The implants are useful in enucleation and evisceration procedures. In enucleation procedures, the implants can be sutured to the eye muscles by either insertion in a scleral sac or other suitable container or, in the cast of spherical hydroxyapatite, sutured to the eye muscles by means of holes in the spheres. After healing, the implant is drilled to receive a peg for fixing an artificial eye to the implant to complete the prosthesis.
