目的：探讨眼眶深部磁性异物摘出术中眶内异物磁铁应用的手术方法和治疗效果。

方法：回顾性分析河北省眼科医院2014-06/2017-05眼眶深部磁性异物住院患者23例23眼的临床资料，其中肌锥外眶内异物14眼，眼球后肌锥内异物9眼。应用眶内异物强力磁铁摘出眶内深部磁性异物，观察异物摘出成功率和术后并发症情况。

结果：肌锥内异物9眼均顺利摘出，成功率100%； 14眼肌锥外眶内异物者中摘出异物12眼，成功率86%。术后轻度眶内出血2眼，未发生视力下降、眶内大量出血、眼球运动受限等并发症。

结论：眼眶深部磁性异物应用眶内异物强力磁铁进行手术，手术创伤小、成功率高、时间短、并发症少。

METHODS: A retrospective analysis of clinical data of patients with deep orbital magnetic foreign bodies(OMFB)in Hebei Eye Hospital from June 2014 to May 2017 was processed. A total of 23 eyes were enrolled, among them, 14 eyes of extraorbital OMFB, 9 eyes of intraorbital OMFB. The rate of extraction of foreign bodies and the postoperative complications were observed.

RESULTS: All eyes of intraorbital foreign bodies were successfully extracted with 100% success rate. Twelve of 14 eyes of extraorbital foreign bodies were extracted with 86% success rate. Mild orbital hemorrhage were found in 2 eyes. There was no other obvious complication such as visual loss, orbital massive hemorrhage or limited ocular movement.

CONCLUSION: It's an ideal surgical method to extract the deep orbital magnetic foreign bodies by mean of an orbital strong magnet, with mini-injury, high success rate, short duration and few complications.
