超大核白内障应用改良梯形切口术的临床研究

Clinical Study on Modified Trapezoidal Incision in the Treatment of Super Large Nuclear Cataract

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.
