摘要
目的 探讨白内障超声乳化摘除联合双焦点人工晶状体植入术治疗老年性白内障的临床疗效及术后视功能.方法 对 59例(118 眼)老年性白内障患者行超声乳化吸除联合人工晶状体植入术,根据植入人工晶状体的类型分为双焦点组以及单焦点组.术后 3 个月随机记录双眼裸眼远、近距离视力及近立体视功能,测定暗环境中不同空间频率(1、2、5、10 cpd)下的对比敏感度,并绘制离焦曲线图.采用VF-14-CN量表进行主观问卷调查,统计脱镜率以及是否有眩光和夜间光晕.结果 与单焦点组相比,双焦点组术后在裸眼近距离视力、矫正远视力基础上的近距离视力、脱镜率以及近立体视功能方面具有更优的满意度,差异存在统计学意义(P均<0.05).但在矫正远距离视力和裸眼远距离视力等方面的差异无统计学意义(P=0.164,P=0.699);而当空间频率在 10 cpd时,双焦点组的左、右眼具有更低的暗视对比敏感度,差异存在统计学意义(P=0.002,P=0.037).两组均有夜间光晕发生,差异具有统计学意义(P<0.001),眩光不适也是两组的共同特点,其差异无统计学意义(P=0.148).结论 与Proming A1-UV单焦点人工晶状体相比,AT LISA 809M双焦点人工晶状体能够帮助老年性白内障患者获得更好的近视力及近立体视功能,术后视觉质量满意度更高.
Abstract
Objective To explore the clinical effect and postoperative visual function of phacoemulsification combined with bifocal intraocular lens implantation in the treatment of senile cataracts.Methods Fifty-nine patients(118 eyes)with senile cataracts were treated by phacoemulsification combined with intraocular lens implantation.The patients were divided into two groups according to the type of intraocular lens implantation:the bifocal group and the monofocal group.Three months postoperatively,the uncorrected distant vision,near vision,and near stereopsis were recorded at random.The contrast sensitivity in different spatial frequencies(1,2,5,and 10 cpd)in a dark environment was measured,and the defocus curve was drawn.A subjective questionnaire(VF-14-CN scale)was conducted to count the rate of off-glasses,and whether there was glare and halo at night.Results Compared with the monofocal group,postoperative satisfaction was superior in the bifocal group in terms of the uncorrected near visual acuity,dis-tance-corrected near visual acuity,glasses detachment rate,and near stereopsis function(all P<0.05).However,there was no sig-nificant difference in corrected distance visual acuity and uncorrected distance visual acuity(P=0.164,P=0.699).When the spatial frequency was 10 cpd,the contrast sensitivity of the left and right eyes in the bifocal group was lower,and the difference was statis-tically significant(P=0.002,P=0.037).Nocturnal halo occurred in both groups and the difference was statistically significant(P<0.001).Glare discomfort was also common in both groups but the difference was not statistically significant(P=0.148).Conclu-sion AT LISA 809M bifocal intraocular lens can help patients with senile cataracts achieve better near visual acuity,near stereopsis vision,and overall satisfaction compared with Proming A1-UV monofocal intraocular lens.
