摘要: 目的:比较小切口劈核法与超声乳化白内障摘除术治疗老年性硬核性白内障的疗效。方法:选择70例(78眼)老年性硬核性白内障患者为研究对象,采用随机数字表法分为观察组和对照组各35例(39眼)。对照组患者接受超声乳化白内障摘除术,观察组患者接受小切口劈核法白内障摘除术。比较2组患者的视力水平、散光程度、不良反应、生活质量。结果:2组患者术前视力水平差异无统计学意义(P>0.05);术后2组患者视力水平较术前均显著改善 (P<0.01),观察组患者术后4周和8周视力水平均高于对照组(P<0.01和P<0.05)。术前2组散光度差异无统计学意义(P>0.05);2组患者散光度术后1周均明显升高,8周后均呈下降趋势(P<0.01和P<0.05);术后同时期2组散光度差异均无统计学意义(P>0.05)。观察组不良反应发生率为25.64%,低于对照组的48.72%(P<0.05);2组患者术后的生活质量评分差异无统计学意义(P>0.05)。结论:综合考虑视力水平、散光程度、生活质量以及术后并发症情况,小切口劈核法白内障摘除术可作为基层医院治疗老年性硬核白内障的方法。Abstract: Objective: To compare the therapeutic effects of small incision nucleus fragmentation method and phacoemulsification cataract surgery in the treatment of senile hard nuclear cataract.Methods: Seventy patients(78 eyes) with senile hard nuclear cataract were randomly divided into the observation group and control group[35 cases(39 eyes),each group].The observation group and control group were treated with the small incision nucleus fragmentation method and phacoemulsification cataract surgery,respectively.The visual acuity,astigmatism degree,adverse reaction and quality of life between two groups were compared.Results: The difference of the visual acuity between two groups before operation was not statistically significant(P> 0.05),the postoperative visual acuity levels in two groups were significantly improved(P<0.01),and the visual acuity levels after 4 and 8 weeks of operation in observation group were higher than those in control group(P<0.01 and P<0.05).The difference of astigmatism degree between two groups before operation was not statistically significant(P>0.05),the astigmatism degree increased significantly after 1 week of operation,and decreased after 8 weeks of operation(P<0.01 and P<0.05).The difference of astigmatism degree between two groups after operation was not statistically significant(P>0.05).The incidence of adverse reaction in observation group(25.64%) was lower than that in control group(48.72%) (P<0.05).The difference of the postoperative quality of life scores between two groups was not statistically significant(P>0.05).Conclusions: According to the visual acuity level,astigmatism degree,quality of life and complications,the small incision cataract extraction and chop technique can be used as the treatment method of senile cataract in the primary hospital.
