摘　　要：目的探讨小切口白内障囊外摘出术中出现虹膜根部断离的修复方法。方法小切口白内障囊外摘出术中出现虹膜根部断离者21例（21眼）。19例行I期修复手术，将断离的虹膜根部用10—0尼龙线缝合至巩膜隧道切口的后唇；2例虹膜根部断离范围小，无需修复。结果术后随访3周～2年，19例经修复后瞳孔形态、位置明显改善，2例无需修复。所有患眼人工晶状体正位、稳定，无明显双瞳，无复视、眩光等不适。结论术中操作不当是造成小切口白内障囊外摘出术中虹膜根部断离的主要原因，需行I期修复手术，可将断离的虹膜缝合至巩膜隧道切口的后唇。Objective To discuss the restoration of iridodialysis occurred during the small incision cataract surgery（SICS）. Methods 21 cases （21 eyes） with iridodialysis in the SICS were managed. Among them , 19 cases were primary repaired by suturing the iris root with the 10 -0 nylon suture through the posterior lip of the sclera tunnel incision. The other 2 cases needed no restoration because of their minor scope. Results The follow-up duration was 3weeks to 2 years. Iridodialysis of the 19 cases was completely cured postoperatively. The shape and position of the pupil were obviously improved. 2 cases needed no resto- ration. All the intraoeular lens implants were stable and reliable. There was no any obviously double pupil in all cases. No patient felt discomfort of diplopia or glare. Conclusions Inappropriate operation is the main cause of iridodialysis in the SICS. The primary restoration is nessary. The iridodialysis can be repaired by suturing through the posterior lip of the sclera tunnel incision.
