During the course of fitting prosthesis, several complications including anophthalmic
enophthalmos, anophthalmic ptosis, extrusion or migration of implant and socket contracture
could develop.
The hydroxyapatite sphere has been used to be a biocompatible implant after enucleation or
evisceration surgery because the hydroxyapatite has been good fibrovascular ingrowth, few
postoperative complications, excellent prosthesis motility and good cosmesis.
The author used the hydroxyapatite as a secondary orbital implant in 19 eyes of anophthalmic
socket patients. Good extra-ocular muscle motility & volume reconstruction after secondary
hydroxyapatite implantation with retaining of peg were obtained.
Average follow-up period was 8 months ranged from 6 to 27 months.
As complications, 3 cases of wound disruption, 2 case of loss of low cul-de-sac were
encountered.
The hydroxyapatite is suggested to be a good biocompatible implant for anophthalmic socket
patients.
