玻璃体磁性异物在经白内障切口摘出方法不可取

目的 探讨经白内障切口“钓鱼法”摘出玻璃体腔磁性异物的方法。方法 4例4眼磁性异物伤所致外伤性白内障、玻璃体腔内异物行白内障摘出，同时经白内障切口用电磁铁经前房吸出玻璃体腔磁性异物。结果 所有异物均一次顺利取出，术后5－10天4例均因出现并发症和玻璃体浑浊伴后脱离、视网膜脱离等而行玻璃体切除术。结论 经白内障切口“钓鱼法”摘出玻璃体腔内磁性异物的方法是不可取的。

Extracting magnetic intraocular foreign body via the incision of cataract surgery.

Objective To investigate the practicable of extracting magnetic intraocular foreign body with electromagnet via incision of cataract surgery.Method Four eyes of traumatic cataract and magnetic intraocular foreign body in the vitreous were treated by extracting cataract and foreign body via incision of cataract surgery and anterior chamber with electromagnet.Results The intraocular foreign bodies were extracted successfully at frist surgery in all cases,but these patients had to accepted the second surgery of vitrectomy for the complications of vitreous opacity and retinal detachment after the first surgery.Conclusion The way of extracting magnetic intraocular foreign body via the incision of cataract surgery is not practicable.
