Ⅳ级以上硬核白内障手术方式的对比研究

目的：对比研究IV级以上硬核白内障两种手术方式的临床应用效果。方法：白内障IV级以上硬核患者150眼分成小切口非超声乳化白内障手术组（74眼）和白内障超声乳化组（76眼）,对两组的核处理时间、术中术后并发症、术后视力进行对比观察。结果：小切口非超声乳化白内障手术组和白内障超声乳化组在核处理时间,虹膜损伤及后囊破裂比较及术后角膜和前房反应比较中,两组间差异有统计学意义（P〈0.05）。术后视力早期差异有统计学意义（P〈0.05）;术后晚期无明显差异（P〉0.05）。结论：小切口白内障手术较超声乳化白内障手术在IV级以上硬核上有优势,是治疗IV级以上硬核白内障较理想的选择。

Comparative study of operative method on above IV grade hard nucleus cataract

AIM：To compare the clinical effects of two operative methods on the Ⅳ grade hard nucleus cataract.METHODS：Totally 150 eyes with cataract above the IV grade hard-core were divided into non-phacoemusification minimal-incision cataract surgery group（74 eyes） and phacoemulisification group（76 eyes）.Nuclear processing time,operating complications and postoperative complications,visual acuity of the two graoups were compared.RESULTS：：There were significant difference between the non-phacoemusification minimal-incision cataract surgery group and the phacoemulsification group in nuclear processing time,operating complications（iris damage and posterior capsule rupture）,postoperative complications（corneal and anterior chamber reaction）,and early vision（P0.05）.There was no significant difference between the two groups in late vision（P0.05）.CONCLUSION：Non-phacoemusification minimal-incision cataract surgery is better than phacoemulsification and it is an ideal method for treating above IV grade hard nucleus cataract.
