AIM: To study the clinical characteristic of early secondary orbital implant insertion of hydroxyapatite in the anophthalmic patients after ophthalmectomy.

METHODS: Sixteen anophthalmic patients(16 eyes)after ophthalmectomy received early secondary orbital implant insertion of hydroxyapatite. The cause, time, future, effect and complications of the operation were analyzed retrospectively. Patients were follow-up for 10(ranged 6 to 13)months.

RESULTS: Severe ocular trauma combining contaminative tissue or sporadic foreign bodies of fossa orbitalis, severe endophthalmitis, ocular tumor, transferring from other hospital were the main causes of the operation of early secondary orbital implant insertion of hydroxyapatite. Sixteen patients received this operation successfully at the 12(ranged 7 to 15)day. All patients had a good cosmetic result and prosthetic motility. There were no complications of implant infection, exposure or extrusion, ptosis in all patients except for bulbar conjunctiva and conjunctival cyst in one patient respectively.

CONCLUSION: Procedure and effectiveness of early secondary orbital implant insertion of hydroxyapatite is similar to one - stage operation. It is safe and effective under the condition of selecting patient reasonably and perfect operation skill.
