方法：回顾性分析16例16眼二期羟基磷灰石义眼台早期植入原因、植入时间、手术特点、手术效果以及并发症。术后随访6～13(平均10)mo。

结果：眼球摘除术后外院转入，严重眼外伤眼眶内组织污染，眼内炎蔓延眼球摘除术后，眼内肿瘤术后是二期羟基磷灰石义眼台早期植入主要原因。16例患者在眼球摘除术后7～15(平均12)d成功行肌锥内二期羟基磷灰石义眼台植入术。术后患者外观改善，义眼台活动度良好，未见感染、义眼台暴露、脱出、眼睑下垂等并发症，1例早期球结膜裂开，再次缝合后愈合，1例结膜囊肿形成，手术切除后无复发。

结论：眼球摘除术后早期二期羟基磷灰石义眼台植入手术过程、效果类似一期义眼台植入。合理选择病例、良好的手术技巧基础上行早期二期羟基磷灰石义眼台植入安全有效。

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.
