【摘要】 目的探讨改良梯形切口非超声乳化囊外摘除术治疗超大硬核白内障的临床疗效。方法 60例(66眼)超大硬核白内障患者,随机分为研究组(30例,34眼)和对照组(30例,32眼)。两组均予以小切口非超声乳化囊外摘除术,研究组采用改良梯形切口,对照组采用直切口。比较两组手术前后视力变化及并发症发生情况。结果术前两组视力比较差异无统计学意义(P>0.05);术后3 d研究组视力为(0.31±0.02),对照组为(0.33±0.01),比较差异无统计学意义(P>0.05)。研究组患者并发症发生率为17.65%,明显低于对照组的43.75%,差异有统计学意义(P<0.05)。结论改良梯形切口非超声乳化囊外摘除术应用于超大硬核白内障治疗中,临床疗效肯定,术后并发症更少,值得临床推广应用。更多还原

【Abstract】 Objective To discuss the clinical efficacy of non-phacoemulsification extracapsular cataract extraction by modified trapezoidal incision in the treatment of super-hard nuclear cataract. Methods A total of 60 patients(66 involved eyes)with super-hard nuclear cataract were randomly divided into research group(30 cases, 34 eyes) and control group(30 cases, 32 eyes). Both groups received non-phacoemulsification extracapsular cataract extraction, and the research group was treated by modified trapezoidal incision. The control group was treated by straight incision. Comparison were made on changes of visual acuity before and after operation and the occurrence of complications between the two groups. Results Both groups had no statistically significant difference in visual acuity(P>0.05). In postoperative 3 d, the research group had visual acuity as(0.31±0.02), which was(0.33±0.01) in the control group, and the difference was not statistically significant(P>0.05). The research group had obviously lower incidence of complications as 17.65% than 43.75% in the control group, and the difference was statistically significant(P<0.05). Conclusion Application of nonphacoemulsification extracapsular cataract extraction by modified trapezoidal incision shows affirmative clinical efficacy in clinical treatment with less postoperative complications, and it is worthy of clinical promotion and application.更多还原
