摘　　要：目的评估垂直劈核联合水平劈核技术在硬核白内障手术中应用的效果.方法回顾性分析2016年6月至2017年5月老年性白内障Ⅳ~Ⅴ级核者86例(86眼),随机分为两组.A组,43例,使用垂直劈核联合水平劈核技术;B组,43例,采用常规高负压劈核技术进行超声乳化手术.对比两组效果.结果A组的超声乳化耗时(67.77±14.68)秒和累积消耗能量35.33±12.75,低于B组的(103.09±44.89)秒和41.25±14.35(P<0.05).术后1天,BCVA>0.3者术眼A组占86.05%,高于B组的67.44%(P=0.04).A组术后1天角膜水肿程度低于B组(P=0.03),术后7天两组差异无统计学意义(P=0.12).术后1个月,A组角膜内皮细胞密度为(2371.30±179.02)个/mm^2高于B组的(2157.80±156.46)个/mm^2(P<0.01);术后内皮细胞丢失率A组为(8.73±3.74)%低于B组的(15.41±3.54)%(P<0.01).结论垂直劈核联合水平劈核技术用于硬核白内障超声乳化术手术效果良好.Objective To evaluate the efficacy of vertical chop combined with horizontal chop in hard nuclear cataract surgery.Methods A retrospective study.Total of 86 eyes of 86 patients with senile cataract were randomly divided into two groups,and all nuclear classification ranged fromⅣtoⅤ.Group A,43 patients,received vertical chop combined with horizontal chop.Group B,43 patients,received phacoemulsification with high vacuum splitting.The efficacy were compared between the two groups.Results The ultrasonic time(UST)was(67.77±14.68)s of group A and(103.09±44.89)s of group.The cumulative dissipated energy(CDE)was 35.33±12.75 of group A and 41.25±.14.35 in group B.The difference in UST and CDE were significant statistically between the two groups(P<0.05).In 1 day after surgery,the best corrected visnal acuity(BCVA)>0.3 occupied 86.05%in group A and 67.44%in group B(P=0.04).The corneal edema at 1 day postoperatively in group A was lower than that in group B,the difference was statistically significant between the two groups(P=0.03).The difference in degree of corneal edema at 7 days after surgery was not statistically significant between the two groups.The corneal endothelial cells(CECs)in 1 month postoperatively was(2371.30±179.02)/mm^2 in group A and(2157.80±156.46)/mm^2 in group B(P<0.01).The loss rate of CECs was(8.73±3.74)%in group A and(15.41±3.54)%in group B(P<0.01).Conclusion Application of vertical nuclear chop combined with horizontal nuclear chop in hard nuclear cataracts surgery is effective.
