瞳孔成形术在外伤性白内障术中的临床应用

目的 探讨瞳孔成形术在合并虹膜损伤的外伤性白内障中的临床应用效果.方法 对34例虹膜根部离断、瞳孔缘裂伤、虹膜萎缩的眼外伤患者,在植入人工晶状体的同时,用10 -0聚丙烯缝线虹膜缝合复位、瞳孔成型或植入带虹膜隔人工晶状体.结果 术后视力0.05～0.1者6例,0.2～0.5者24例,≥0.6者4例.修复后瞳孔接近正常者24例,占70.6％.结论 在复合性眼外伤中,行白内障摘出的同时修复损伤的虹膜,可起到改善瞳孔外观和提高视力的作用,但手术操作较复杂.

Performation of iridoplasty in traumatic cataract surgery

Objective To explore the effect of iridoplasty on cataract surgery in traumatic cataract with iris injury. Methods Iridoplasty combined with cataract extraction mad intraocular lens implantation were performed on 34 cases of traumatic cataract with iris trauma： iridodialysis, iris dehiscence or iris atrophy. Results Postoperative visual acuity were 0.05 - 0.1 in 6 eyes, 0.2 - 0.5 in 24 eyes, 0.6 or better in 4 eyes. Pupils of 24 eyes had been closed to normal postion （70.6%）. Conclusion The iridoplasty was necessary and important in intraocular lens implant surgery in those cases with serious iris and lens injury.
