早期学习SMILE手术的术中并发症分析

Analysis of intraoperative Complications in early Learning stage of SMILE Surgery

目的探讨早期学习小切口角膜基质透镜取出术(SMILE)的术中并发症的发生情况。方法连续选取100例(200只眼)行双眼SMILE手术患者。按手术时间先后顺序分组,前50例(100只眼)为1组,后50例(100只眼)为2组。手术均由同一位经SMILE系统培训且具有丰富眼科显微手术基础的医生完成并记录术中并发症情况。结果两组患者之间年龄、等效球镜、角膜厚度和透镜厚度比较差异无统计学意义(P>0.05)。计划外透镜后表面先分离在两组的发生率分别为5%(5/100)和4%(4/100);透镜边缘撕裂发生率分别为4%(4/100)和1%(1/100);帽小切口撕裂发生率分别为3%(3/100)和1%(1/100)。以上所列的术中并发症发生率在两组之间比较均无统计学差异(均P>0.05)。结论SMILE手术早期并发症发生率较高,但通过经验的积累,并发症发生率有所降低。

Objective To explore the intra-operative complications of small-incision lenticule extraction(SMILE)in the early experience.Methods A total of 100 cases(200 eyes)underwent bilateral SMILE surgery were included.According to the sequence of operation time,the first 50 cases(100 eyes)were sorted as group 1 and the last 50 cases(100 eyes)were sorted as group 2.All surgeries were performed by the same doctor who was trained systematically and experienced in microsurgery.All the complications were recorded.Results There was no significant difference in age,equivalent spherical lens,corneal thickness and lens thickness between the two groups of patients(P>0.05).unplanned posterior surface first-separation was in the two groups was 5%(5/100)and 4%(4/100);lenticule edge tearing was 4%(4/100)and 1%(1/100);cap small incision tearing was 3%(3/100)and 1%(1/100);No significant differences were found in those complications occurrence rates between the 2groups(all P>0.05).Conclusios SMILE has a high rate of complications in early stage but the incidence of complications will be somewhat reduced with the accumulation of experience.
