摘要
目的:比较预劈核与非预劈核两种劈核方式,探讨撕囊镊预劈核的技术优点。方法:将年龄相关性白内障患者149例149眼随机分为预劈核组(A组)77眼和非预劈核组(B组)72眼。分别使用撕囊镊预劈核和非预劈核技术进行白内障超声乳化术,记录术中超声能量、平均超声乳化时间、术中并发症、术后1d,1wk裸眼视力和术后1、3d,1wk角膜水肿等情况并进行比较。结果:将两组中同级核硬度的亚组进行比较,A组的平均超声乳化时间低于B组,差异有统计学意义(P<0.05);且前者术后第1、3d角膜水肿轻于后者,差异有统计学意义(P<0.05),术后1d裸眼视力A组优于B组,差异有统计学意义(P<0.05),术后1wk两组裸眼视力无统计学差异(P>0.05)。术中出现晶状体后囊膜破裂A组2眼(2.6%),B组有3眼(4.2%),两组比较,差异无统计学意义(χ~2=0.28,P>0.05)。结论:与非预劈核相比,撕囊镊预劈核操作更简便,术中超声时间更短,角膜水肿程度更轻,术后早期裸眼视力更好。
AIM： To compare the two techniques of pre-chop and non-pre-chop, and discuss the technical advantages of the capsulorhexis forceps assisted pre-chop. METHODS： Totally 149 cases of age-related cataract were randomly divided into using pre-chop （Group A） and non- pre- chop （Group B） techniques groups, for Group A patients received phacoemulsification after pre- chop by using capsulorhexis forceps. The ultrasonic energy, average phacoemulsification time, intraoperative complications, ld, lwk uncorrected visual acuity （UCVA） and l d, 3d, l wk postoperative corneal edema were recorded and compared. RESULTS： The subgroups of the same group of nuclei were compared in the two groups. The ultrasonic time in Group A was lower than that of Group B, and the difference was significant （ P〈 0. 01 ）. Also the corneal edema in the former was lighter than that of the latter（ P〈 0.05）. There was difference in uncorrected visual acuity （UCVA） between groups（P〈0.05）. CONCLUSION ： Compared with non-pre-chop, the time of ultrasound in pre-chop group was shorter, the degree of corneal edema was lighter and early postoperative UCVA was better.
