目的探讨硬核白内障手法劈核方法及临床效果.方法对172例(172眼)Ⅳ ～Ⅴ级硬核的白内障行5.5 mm带球结膜瓣的角巩膜隧道式切口,将核劈分为2～3块后摘出,植入5.5 mm直径的硬质人工晶状体.观察术中术后并发症及术后视力.结果环形撕囊成功160例,成功率93.0％；后囊破裂5例,占2.9％；均植入人工晶状体,植入率100％.术后1d视力≥0.3者136眼,占79.1％；术后7d视力≥0.3者148眼,占86.0％.术后角膜轻中度水肿59眼,占34.3％,术后1～2周完全消退.结论经5.5 mm角巩膜隧道式切口手法劈核摘出术可以明显减小切口大小,提高手术疗效,是一种效果好,较为安全的手术方法.

Objective To investigate the surgical technique and clinical effect of manual chop for hard nucleus cataract.Methods 172 cases (172 eyes) of Ⅳ ～ Ⅴ grade hard nucleus cataract were observed.5.5 mm scleral tunnel incision in limbus,the nucleus were splited into 2 ～ 4 blocks to be extracted and implantation of 5.5mm diameter rigid intraocular lens.The intraoperative and postoperative complications and postoperative visual acuity were observed.Results Circular capsulorhexis was successful in 160 cases,and the success rate was 93％ ; posterior capsular rupture in 5 cases (2.9％),intraocular lens were implanted in all patients (100％).The visual acuity was 0.3 or better in 136 eyes (79.1％) at 1 day after surgery.The visual acuity was ≥0.3 in 148 eyes(86％) at 7 days after surgery.Mild to moderate postoperative corneal edema in 59 cases(34.3％),subsided completely at 1 ～ 2 weeks postoperatively.Conclusion The 5.5 mm scleral tunnel incision combined with manual nucleus chop can obviously reduce the incision size,improve the effect of operation,is a kind of effective,safe operation method.
