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白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1 d的视力≥0.5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≥0.5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,(1.21±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.

abstractsObjective 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 caees(96 eyes)in group A had undergone chop hook combine with micro-forceps nuclear chopping technique for cataract surgery and intraocular lens implantation.89cases(89 eyes)in group B were pedormed phacoemulsification and intraocular lens implantation.Visual acuity,astigmatism and endothelial cells were observed before and after operation.Results The visual acuity was more than 0.5 in 42 cases(43.7％)in group A and 49 cases(55％)in group B one day after operation,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±0.74)D,(0.93+0.57)Din group B 1 w,1m,3m after operation.There were no significant difference between the two groups.The endothelial cell loss rate was(13.1 ± 3.6)％ in group A and(12.5 ± 2.9)％ in group B.There were no signriflcant difference between the two groups(P ＞ 0.05).Conclusion Chop hook combine with micro-forceps nuclear chopping technique is a simple and effective way for hard nuclear cataract surgery.
