不同手术方式治疗白内障的疗效分析

目的:比较小切口非超声乳化摘除术及同轴微切口2.2 mm与2.8 mm切口白内障超声乳化手术的疗效.方法:选择白内障病人112例(112眼),随机分成小切口组(38例38眼)、2.2 mm组(37例37眼)和2.8 mm组(37例37眼).比较术前、术后1周及术后1个月裸眼视力、最佳矫正视力、屈光状态、角膜内皮细胞计数及术后并发症发生情况.结果:3组病人术后裸眼及最佳矫正视力与术前相比均有明显提高(P<0.01);术后1周、1个月,3组病人视力提高幅度为小切口组>2.2 mm组或>2.8 mm组(P<0.01).3组病人术后角膜散光较术前明显降低(P<0.01),但术后1周、1个月时3组病人角膜散光度差异无统计学意义(P>0.05).3组病人术后角膜内皮细胞计数均显著下降(P<0.01),但组间差异无统计学意义(P>0.05).3组病人术后并发症发生率差异无统计学意义(P>0.05).结论:小切口非超声乳化摘除术具有创伤小、恢复快、术后裸眼视力好、费用低、操作简便等优点,是一种值得推广的手术方式.

Analysis of clinical effect of different surgical methods in the treatment of cataract

Objective:To compare the efficacy between small incision non phacoemulsification,and coaxial micro incision 2. 2 mm and 2. 8 mm incision phacoemulsification. Methods:One hundred and twelve patients(112 eyes) with cataract were randomly divided into the small incision group(38 cases),2. 2 mm group(37 cases) and 2. 8 mm group(37 eyes). The uncorrected visual acuity,best corrected visual acuity,refractive status,corneal endothelial count and postoperative complications before operation,after 1 week and 1 month between three groups were compared. Results:Compared with before operation,the uncorrected visual acuity and best corrected in three groups were significantly improved after operation(P<0. 05). The increasing degree of vision in small incision group,2. 2 mm group and 2. 8 mm group after 1 week and 1 month gradually decreased(P<0. 01). Compared before operation,the corneal astigmatism in three groups significantly decreased after operation(P<0. 01),and the differences of the corneal astigmatism after 1 week and 1 month of operation between three groups were statistically significant(P>0. 05). The corneal endothelial cell counts in three groups significantly decreased after operation(P<0. 01),the differences of which between three groups were not statistically different(P>0.05).There was no significant difference in the incidence rate of complications between the 3 groups after surgery(P >0. 05). Conclusions:Small incision non phacoemulsification has the advantages of small trauma,quick recovery,good vision of naked eye,low cost and easy operation,which is worthy of promotion.
