摘　　要：目的:对比研究自制垂直刃超薄劈核刀预劈核与传统拦截劈核用于白内障超声乳化中的效果。方法:选取2019年12月-2020年10月于本院接受白内障劈核手术的患者78例,随机数表法分为A组(39例56眼)和B组(39例60眼),所有患者均接受白内障超声乳化手术治疗,A组患眼使用本院自制垂直刃超薄劈核刀和劈核钩进行预劈核,B组患眼使用超声乳化拦截劈核技术进行劈核。比较两组患眼劈核成功率、超声乳化时间(UST)、超声乳化消耗能量(CDE)。比较手术前和术后3个月时最佳矫正视力(BCVA)、角膜内皮细胞(CEC)情况(计数、丢失率)。比较术后1个月内两组患眼并发症发生率(角膜内皮水肿、囊破裂、晶体脱位)。结果:A组患眼劈核成功率明显高于B组患眼,UST和CDE均明显短或低于B组(P<0.05)。术后3个月时两组患眼BCVA较治疗前均有明显升高,且A组高于同一时间B组;两组患眼CEC计数明显低于术前,且A组患眼明显高于B组,A组患眼CEC丢失率明显低于B组(P<0.05)。术后1个月内A组后囊破裂、晶体脱位发生率、患眼角膜内皮水肿发生率均明显低于同一时间B组患眼(P<0.05)。结论:自制垂直刃超薄劈核刀用于白内障超声乳化手劈核成功率较高,可明显减少超声乳化时间和能量,减少角膜内皮细胞损伤和并发症发生风险。Objective:To comparatively study the effects of self-made vertical-blade ultra-thin nuclear chopper and traditional stop-and-chop in phacoemulsification.Method:A total of 78 patients who underwent cataract nucleus chopping surgery in our hospital from December 2019 to October 2020 were selected and divided into group A(39 cases,56 eyes)and group B(39 cases,60 eyes)according to the random number table method.All patients received phacoemulsification surgery with nucleus pre-chopping,and group A was given self-made vertical-blade ultra-thin nuclear chopper and nucleus chopping hook for nucleus pre-chopping,and group B applied traditional stop-and-chop tool for nucleus chopping.The success rate of nucleus chopping of affected eyes,phacoemulsification time(UST),and phacoemulsification energy consumption(CDE)were compared between the two groups.The best corrected visual acuity(BCVA)and corneal endothelial cell(CEC)status(count,loss rate)were compared before surgery and at 3 months after surgery.The incidence rates of complications(corneal endothelial edema,capsule rupture,lens dislocation)were compared between the two groups within 1 month after surgery.Result:The success rate of nucleus chopping of affected eyes in group A was significantly higher than that in group B while the UST and CDE were significantly lower than those in group B(P<0.05).At 3 months after surgery,the BCVA of affected eyes of the two groups was significantly higher than that before treatment,and the BCVA of group A was higher than that of group B at the same time point.The CEC count of the two groups was significantly lower than that before surgery,and the CEC count of group A was higher than that of group B,and the loss rate of CEC of affected eyes in group A was significantly lower than that in group B(P<0.05).The incidence rates of corneal endothelial edema,capsule rupture and lens dislocation in group A were significantly lower than those in group B(P<0.05).Conclusion:Self-made vertical-blade ultra-thin nuclear chopper has a high success rat
