小切口非超声乳化白内障摘除术中水压法与圈套器法娩核的疗效比较

Comparison of clinical effects of nucleus delivery between hydraulic pressure and lens loop method in manual small incision cataract surgery

目的:对比白内障小切口非超声乳化晶状体摘除手术中水压法娩核与圈套器法娩核两种方法的疗效及并发症。方法:白内障患者226例253眼随机分为水压法娩核与圈套器法娩核两组,观察两组不同方法治疗患者手术时间、术中术后并发症、术前与术后角膜内皮计数及黄斑区视网膜厚度变化的情况。结果:术中娩核平均时间:水压法娩核组5±0.79s,圈套器法娩核组4±1.23s;术中并发症:水压法娩核组少于圈套器法娩核组;术前与术后角膜内皮计数的差值两组相比有统计学差异;两组之间术后散光的差异无统计学意义;术前与术后黄斑区视网膜厚度差异两组相比无统计学差异。结论:同圈套器法娩核治疗白内障相比较,水压法娩核疗效好、简单易行、且能够减少并发症。

AIM： To compare the clinical effects of nucleus delivery between hydraulic pressure and lens loop method in manual small incision cataract surgery （MSICS）. METHODS： Totally 226 cases of cataract patients 253 eyes were randomly divided into hydraulic pressure nucleus delivery group and lens loop nucleus delivery group. The operating time, complications, corneal endothelial count and macular retinal thickness were observed preoperatively and postoperatively in both groups. RESULTS：The average time of nucleus delivery： hydraulic pressure was 5±0.79s in nucleus delivery group and 4±1.23s in lens loop nucleus delivery group; complications in hydraulic pressure nucleus delivery group were less than those in lens loop nucleus delivery group. The corneal endothelial count before and after operation between the two groups was significantly different; the astigmatism after operation was not statistically different; the macular retinal thickness was not statistically different. CONCLUSION：Compared with the lens loop method, the hydraulic pressure nucleus delivery method is an effective, feasible, and economical approach with less complications for cataract surgery. 
