摘　　要：目的评价劈核钩联合显微镊劈核技术在硬核白内障手术中的效果。方法将在我院接受扫盲手术的硬核自内障患者随机分成两组。A组96例（96眼），应用劈核钩联合显微镊劈核技术进行白内障手术。B组89例（89眼），应用超声乳化技术进行白内障手术，两组均植入硬性人工晶状体。术前、术后1d、1个月、3个月，检查视力，术后1周、1个月、3个月检查散光度，术前、术后1个月检查角膜内皮细胞计数等，进行对比。结果A组术后1d的视力〉10．5为42例（43．7％），B组视力≥0．5者49例（55％）。两组差别有统计学意义（P〈0．05）。术后3个月A组视力≥O．5者为88例（91．6％）B组为83例（93．2％），两组差别无统计学意义（P〉0．05）。术后1周，1个月，3个月平均散光度A组为（1．41±0．92）D，（1．214-0．83）D，（0．96±0．61）D，B组为（1．37±0．81）D（1．10±0．74）D，（0．93±0，57）D。两组对比差异无统计学意义（P〉0．05）。术后A组内皮丢失率为13．1±3．6％，B组为12．45±2．9％，两组差异无统计学意义（P〉0．05）。两组均无角膜内皮失代偿等严重并发症。结论劈核钩联合显微镊劈核技术是一种方法简便、效果确切的手术方法，特别适合于基层医院硬核白内障手术。Objective To evaluate the clinical efficacy of chop hook combine with micro-forceps nuclear chopping technique for hard nuclear cataract patients. Methods 185 hard nuclear cataract patients had been divided into two groups randomly . 96 cases （96 eyes） in group A had undergone chop hook com- bine with micro-forceps nuclear chopping technique for cataract surgery and intraocular lens implantation. 89 cases （89 eyes） in group B were performed phacoemulsification and intraocular lens implantation. Visual a- cuity, astigmatism and endothelial cells were observed before and after operation. Results The visual acui- ty was more than 0.5 in 42 cases（43.7% ） in group A and 49 cases（55% ） in group B one day after opera- tion , there was significant difference between two groups （ P 〈 0. 05 ）. However the visual acuity was more than 0.5 in 88 cases（91.6% ） in group A and 83 cases（93.2% ） in group B three months after operation, there was no significant difference between the two groups （P 〉 0. 05）. The astigmatism was （1.41 ± 0.92） D,（1.21 ±0.83）D,（0.96 ±0.61）D in group A and （1.37 ±0.71）D, （1.1 ±.74）D,（0.93±0.57）D in group B 1 w, 1 m,3m after operation. There were no significant difference between the two groups. The en- dothelial cell loss rate was （13.1 ±3.6）% in group A and （12.5 ±2.9）% in group B. There were no sig- nificant difference between the two groups （ P 〉 0.05 ）. Conclusion Chop hook combine with micro-for- ceps nuclear chopping technique is a simple and effective way for hard nuclear cataract surgery.
