摘　　要：目的：探讨外伤性白内障合并前段玻璃体腔磁性异物伤的简易手术方法及其疗效观察。 方法：术前评估13例眼球异物穿通伤,对外伤性白内障后囊穿破合并前段玻璃体腔磁性异物的病例作改良手术方法,伤眼行白内障抽吸及清除脱出的玻璃体后,在双目间接检眼镜直视下经角巩缘切口用稀土磁棒将玻璃体腔磁性异物取出,观察术后眼内情况及视功能恢复情况。 结果：患眼13例均于直视下成功取出异物,手术过程快捷顺利,未出现继发出血或感染等并发症,矫正视力均有较大程度的提高。随诊6 mo矫正视力〉0.3者10例,0.1～0.3者3例。 结论：在双目间接检眼镜直视下进行异物定位,使用眼内稀土磁棒准确磁吸取出异物,操作简单安全,是一个可靠的手术方式选择。AIM：To investigate the curative effects on a modified simple removal surgery of magnetic foreign body in the anterior part of vitreous cavity combined with traumatic cataract. METHODS： Data were collected on 13 patients with ocular penetrating and perforating injuries combined with traumatic cataracts and magnetic foreign bodies in the anterior part of the vitreous cavity who underwent a simple modified removal surgery. Under direct vision of binocular indirect ophthalmoscope, the intraocular earth magnet was applied to remove the magnetic foreign bodies after clearance of the turbid lens and prolapsed vitreous. Postsurgical intraocular reaction and recovery of the visual function were observed and evaluated. RESULTS： Under the direct vision, by using this surgery method, all the magnetic foreign bodies were successfully removed smooth and fast. No complication such as secondary bleeding or infection occurred. Corrected visual acuity has been improved obviously in all these patients who underwent operation. The postoperative follow up of 6mo showed that the BCVA of 10 cases was ＆gt;0. 3. BCVA of the other 3 cases was 0. 1-0. 3. CONCLUSION： Under direct vision of binocular indirect ophthalmoscope, the magnetic foreign bodies in the anterior part of vitreous cavity can be removed accurately by using intraocular earth magnet. This modified method is simple and safe. And it is a reliable surgical option for these patients.
