硬核年龄相关性白内障小切口非超声乳化和超声乳化手术临床疗效比较

目的：对比观察硬核年龄相关性白内障采用小切口非超声乳化手法劈核和超声乳化手术治疗的临床疗效。方法：分别实施小切口非超乳手法劈核手术210例和超声乳化手术161例，同期联合人工晶体植入术治疗硬核年龄相关性白内障共371例，比较术后视力、术后散光以及术中、术后并发症。结果：两组术后视力均较术前提高。术后1周和3个月，患者的并发症、术后视力和散光组间比较差异无统计学意义（P〉0．05）。角膜水肿在术后1周均消退。结论：小切口非超乳手法劈核术后并发症少，操作简单，较超声乳化方法更易掌握。与超声乳化相比，远期效果相同。

Clinical Observation of Small Incision Manual Fragmentation Nonphacoemulsification and Phacoemulsi- fication in Age Related Hard Cataract

Objective：To compare the difference of clinical efficiency between small manual incision fragmentation nonphacoemulsification and phacoemulsification in age related hard cataract. Methods：Complica tion, postoperative vision and astigmatism between 210 cases of small incision manual fragmentation nonphaco and 161 cases of phaco with IOL implantation for patient of age related hard cataract were retrospectively ana lyzed. Results：Postoperative vision of the both groups was improved. There was no significant difference be tween two groups in postoperative vision, astigmatism after lm and 3m of postoperation. Corneal edema disap peared in 1 w after postoperative treatment of the both groups. Conclusions ： The postoperative efficiency of two groups is almost the same. Small incision manual fragmentation nonphaco is safer and more easily to handle with fewer complications compared with phaco. Both groups have the same long term effect.
