AIM: To evaluate the clinical effect of hydroxyapatite(HA) orbital implant. METHODS: Thirty-two cases with HA orbital implant performed in our hospital were observed. In these cases,18 cases of HA orbital implants were in stage Ⅰ, 14 cases were in stage Ⅱ. RESULTS:HA orbital implants were performed in 32 cases, failed in 3 patients. 29 patients underwent successful surgery without major complications. There was no implant extrusion or exposure in the series examination.No patient had the depression of orbit or ptosis. No patient had sympathetic ophthalmia during the follow-up. CONCLUSION:In strictly selected cases, HA orbital implant is a safe and effective method for patients with severe eyeball rupture, blind, painful or atrophic eye.
