【摘要】目的 研究超大核白内障应用改良梯形切口术的临床疗效。方法 对照组患者给予常规切口白内障摘除术，研究组患者给予改良梯形切口白内障摘除术。术后3 d对比两组患者不同视力范围比率分布，同时观察两组术后并发症。结果 两组术后视力低于0．1、视力0．1～0．3及视力高于0．3患者比率差异无统计学意义（P＞0．05）。研究组术后并发症发生率为20．37%，低于对照组的46．30%（P＜0．05）。结论 超大核白内障应用改良梯形切口术能够在保障疗效的同时，降低术后并发症的发生率，改善患者预后。

Objective To study the clinical effect of modified trapezoidal incision in the treatment of super large nuclear cataract． Methods Patients in the control group were given conventional incision cataract extraction，the study group were treated with modified trapezoidal incision cataract extraction． The rate of two groups of patients with different visual acuity were compared after the operation，and the postoperative complications of the two groups were observed and compared． Results There was no significant difference between the two groups in the postoperative visual acuity of less than 0．1，0．1 to 0．3 and visual acuity above 0．3（P＞0．05）． The incidence rate of postoperative complications in the study group was 20．37%，which was significantly lower than that of the control group 46．30%（P＜0．05）． Conclusion The modified trapezoidal incision in the treatment of super large nuclear cataract can reduce the incidence of complications and improve the prognosis of patients．

临床白内障最有效的干预方式即为手术治疗。常规软核白内障实施超声乳化手术或非超声乳化小切口手术其疗效均理想，但是若晶状体核过大过硬，无论是超声乳化还是常规小切口手术均具有手术难度，经常造成角膜受损，甚至导致后囊破裂［1］，酿成手术事故。为此，我院积极针对此类患者改良眼科术式，给予其改良梯形切口术进行治疗，以期在保障疗效同时减少术后并发症的发生，现报道如下。

1 资料与方法

1.1 一般资料

本次研究对象为本院2013年7月～2015年12月确诊并收治的108例白内障患者。所有患者均系单眼发病。全部患者经由眼科专科检查确诊，其晶状体核硬度分级［2］为V级，即大又为硬核。所有患者合计男53例、女55例。年龄52～80岁，平均（74.6±6.3）岁。同时排除了合并其他眼部疾病、合并眼外伤、严重基础疾病、白内障手术禁忌证、实验药物过敏等不宜纳入研究的情况。……
