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例均因出现并发症如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
Objective To explore the method of extracting magnetic foreign bodies in vitreous cavity by “fishing method” through cataract incision. Methods Four cases of traumatic cataract caused by magnetic foreign body injury in 4 cases and cataract in vitreous cavity were excised. At the same time, the magnetic foreign bodies in the vitreous cavity were aspirated through the anterior chamber through the cataract incision with electromagnet. Results All foreign bodies were removed smoothly. Four cases were found to have vitrectomy after vitreous opacity with posterior detachment and retinal detachment in 5 to 10 days after operation. Conclusion The cataract incision “fishing” method of removing magnetic foreign bodies in the vitreous cavity is not desirable
