Orbital implants.

Several aspects of orbital implants are reviewed. Hydroxyapatite has become one of the most commonly used implants for anophthalmic patients and has many of the characteristics desirable in an implant, although reports of significant complication rates are noted. Recent editorials acknowledge the advancement that hydroxyapatite has given in treating anophthalmic patients but add a note of caution in its extensive use. It may be reasonable to limit the use of hydroxyapatite to patients who are highly motivated. Other recent advances in surgical technique, evaluation, and treatment of complications from hydroxyapatite are discussed. In addition, recent trends in treating orbital fractures are reviewed.
