目的探讨上方透明角膜隧道切口术和颞侧透明角膜隧道切口两种切口术后对视力及角膜散光的影响。方法收集我院2012年6月~2013年9月治疗的80例白内障患者，共88眼，随机分成上方透明角膜隧道切口术组和颞侧透明角膜隧道切口术组各40例，44眼，上方透明角膜隧道切口组采用上方透明角膜隧道切口术进行治疗，颞侧透明角膜隧道切口两种切口组采用颞侧透明角膜隧道切口两种切口术进行治疗。结果术后1w、术后3个月、术后6个月颞侧透明角膜隧道切口术组视力恢复情况明显优于上方透明角膜隧道切口术组，术后1w、术后3个月、术后6个月上方透明角膜隧道切口术组角膜散光情况明显高于颞侧透明角膜隧道切口术组，两组比较有显著性差异（约0.05）。结论颞侧透明角膜隧道切口术明显优于上方透明角膜隧道切口术，颞侧透明角膜隧道切口术应在小切口白内障手术中首选的切口方式。“,”Objective To investigate the clear corneal tunnel incision above and temporal clear corneal tunnel incision of two kinds of incisions on the vision and corneal astigmatism. Methods In our hospital from 2012 June to 2013 September treatment of 80 cases of cataract patients, 88 eyes, were randomly divided into upper clear corneal tunnel incision group and temporal clear corneal tunnel incision group with 40 cases in each group, 44 eyes, over a transparent corneal tunnel incision group with over a transparent corneal tunnel incision for treatment, temporal side of the transparent corneal tunnel incision of two incision group with temporal clear corneal tunnel incision of two kinds of incisions were treated. Results Superior clear corneal tunnel incision group above 6 months of recovery temporal clear corneal tunnel incision group vision after 1 weeks, 3 months after the operation, after operation, 1 weeks after operation, 3 months after operation, postoperative above 6 months clear corneal tunnel incision corneal astigmatism the situation is remarkably higher than that of temporal clear corneal tunnel incision group, there were significant dif erence between two groups ( < 0.05). Conclusion Temporal clear corneal tunnel incision was bet er than the above transparent corneal tunnel incision, temporal clear corneal tunnel incision in small incision cataract operation in the first choice of incision.
