目的:探讨小切口非超声乳化术中隧道切口制作技巧的相关问题。方法:分析研究368眼小切口白内障手术中构筑切口不当引起的并发症和影响手术操作的相关问题。总结出隧道切口制作相关技巧。结果:术中术后因切口操作不当引起角膜水肿、虹膜损伤、前房出血、悬韧带断裂、后囊破裂及玻璃体脱出等并发症以及引起切口渗漏、虹膜脱出、前房波动、撕囊、娩核及植入人工晶状体困难等操作难点共56眼,占15.2%。其中切口形状不规则15眼,占26.8%;切口过小11眼,占19.6%;隧道太浅8眼,占14.3%;隧道太深6眼,占10.7%;隧道过短11眼,占19.6%;隧道过长5眼,占8.9%。结论:小切口非超声乳化术中切口制作不当会影响手术操作及产生并发症。所以,隧道切口的制作要严格按照切口构筑原则进行,熟练掌握制作技巧。正确隧道切口是手术成功的关键。

AIM:To discuss the related issues of tunnel incision production techniques in small incision non-phacoemulsification.METHODS:Complications and related issues impacting operation due to improper construction of incision in small incision cataract surgery of 368 eyes were analysed.The tunnel incision production related skills were summed up.RESULTS:Due to incision misoperation,complications of corneal edema,iris damage,hyphema,suspensory ligament rupture,posterior capsule rupture and vitreous prolapse and operational difficulties of incision leakage,iris prolapse,anterior chamber fluctuations,capsulorhexis,nuclear delivery and difficulty of intraocular lens implantation were in total 56 eyes intraoperatively and postoperatively,accounting for 15.2%.There fore,incision was irregular in 15 eyes,accounting for 26.8%;incision was too small in11eyes,accounting for 19.6%;tunnel was too shallow in 8 eyes,accounting for 14.3%;tunnel was too deep in 6 eyes,accounting for 10.7%;tunnel was too short in 11eys,accounting for 19.6%;tunnel was too long in 5 eyes,accounting for 8.9%.Correct tunnel incision was key to successful operation.CONCLUSION:Improper production of surgical incision in small incision non-phacoemulsification will affect operation and cause complications.Therefore,the tunnel incision should be constructed in strict accordance with the incision construction principle,and production skills should be mastered.
