1、钩刀劈裂法在非超声乳化小切口白内障囊袋内劈核术中的临床应用作者：卜继普，陈向东,吴柳青，肖羽辉,彭素霞单位：410300)中国湖南省浏阳市眼科医院【摘要】目的：设计一种合理的非超声乳化小切口白内障囊袋内劈核方法应用于临床，并观察其效果。方法：用自行设计的劈核器械和术式行III级核以上白内障囊袋内劈核。随机将III〜V级核白内障399眼分成两纽。囊袋内劈核组(实验纽.)211眼，前房内劈核纽.(对照组)188眼。实验纽.及对照组均行连续环形撕囊(contrnuouscircularcapsulorhexis,CCC)A分水分离，实验纽•在粘弹剂的保护下用钩刀
2、劈裂法行囊袋内劈核；对照纽将核旋出囊袋浮至前房，在粘弹剂的保护下用双刀水平面劈核法，行前厉内劈核，均劈成两块核瓣。扩大切口至5.5mm,用3mm圈匙娩出核瓣。观察两纽术后1,7d视力、术后反应及并发症情况。结果：两组术后第Id视力及术后反应，术后近期并发症比较，经统计苧处理均有显著意义(P<0.01)。两纽术后第7d视力，并发症和角膜散光度数无统计学意义。结论：非超声乳化小切1丨白内障囊袋内劈核比前厉内劈核术后短期反应更轻，并发症少，是一种非超声乳化白内障手术更合理的劈核方法。同时可作为超声乳化手术初学者过渡术式。【关键词】白内障；非超声乳化；劈核；
