小切口非超声乳化白内障手术水法娩核与圈套器娩核方法的对比

Comparision of extracting nucleus using water irrigation and lens loop during nonphacoemulsification with small incision

目的:对比小切口非超声乳化白内障摘除手术中水法娩核及圈套器法娩核两种方法。方法:326例老年性白内障成熟期患者随机分成水法娩核及圈套器法娩核两组,观察对比两种娩核方法晶体核娩出操作时间、术中并发症及术后角膜水肿情况。结果:娩核操作时间:水法娩核组平均时间20s,圈套器组平均时间90s,水法娩核组手术并发症较少。术后角膜水肿情况:水法娩核组:0级97眼,1～4级82眼;圈套器组:0级39眼,1～4级108眼。两组结果有明显差异(x2=24.28,P<0.01)。结论:水法娩核具有操作快速简便、组织损伤轻、术中并发症少、角膜水肿发生率低等优点,适用于基层医院开展大规模的白内障扫盲手术。

AIM： To compare the clinical effect of extracting nucleus using water irrigation and lens loop during nonphacoemulsification with small incision. METHODS： 126 cases senile cataract underwent Nonphacoemulsification with small incision were divided into water irrigation group and lens loop extracting nucleus group randomly, and to compare the time of extracting nucleus , complication during operation and corneal edema after operation. RESULTS： There was obvious difference of corneal edema between the two groups（ χ^2=24.28, P〈0.01）, corneal edema in water irrigation group were 0 class 97 eyes and i to 4 class 82 eyes; and in lens loop group were 0 class 39 eyes and 1 to 4 class 108 eyes. The average extracting nucleus times were 20″ in water irrigation group and 1′30″ in lens loop group respectively, and the complication in water irrigation group was less than that in lens loop group. CONCLUSION： Extracting nucleus using water irrigation should be applied extensively in basic-level hospital due to simple operation methods, less injury, less complication and lower happened rate of corneal edema.
