方法：回顾性分析我院2012-01/2013-12行玻璃体切割联合电磁铁吸引手术治疗不规则球内磁性异物患者30例30眼与我院2010-01/2011-12行单纯玻璃体切割治疗球内异物患者30例30眼的临床疗效。对两组患者术中异物取出情况、术中及术后并发症进行比较。

结果：玻璃体切割联合电磁铁吸引取出异物的患者中有28眼(93%)异物均一次取出，单纯应用玻璃体切割取出异物的患者中有20眼(67%)异物一次性取出，两者比较差异有统计学意义(χ²=5.333，P=0.021)，玻璃体切割联合电磁铁吸引取出异物的患者在术中、术后的并发症均少于单纯应用玻璃体切割取出异物的患者。

结论：不规则球内金属异物玻璃体切割异物取出术中联合应用电磁铁具有一定优势，可以在临床工作中加以推广。

METHODS:Clinical data of 60 cases(60 eyes)from January 2012 to December 2013 with intraocular magnetic foreign bodies were retrospective analyzed. Thirty eyes underwent vitrectomy only, and electromagnet was applied in the other 30 eyes underwent vitrectomy. The success rate and complications in and after operations were compared between the two groups.

RESULTS:Twenty-eight(93%)patients had their foreign bodies removed successfully at the first time in electromagnet group and twenty(67%)patients in vitrectomy group,there was statistic significant difference(χ²=5.333,P=0.021). Fewer complications happened in and after operations when electromagnet was used.

CONCLUSION:The application of electromagnet shows advantage in vitrectomy for irregular intraocular magnetic foreign body removal and it deserves promotion.
