摘要:
目的：观察并比较AT LISA tri 839MP三焦点人工晶体及CT SPHERIS 209M单焦点人工晶体植入术后高度近视患者的视力、对比敏感度和视觉质量。方法：行白内障超声乳化摘除联合人工晶体植入术的患者44例（44眼），其中三焦组22例（22眼），术中植入AT LISA tri 839MP三焦点人工晶体，单焦组22例（22眼），术中植入CT SPHERIS 209M单焦点人工晶体。术后3个月检查患者的裸眼远距离视力（uncorrected distance visual acuity，UCDVA）、裸眼中距离视力（uncorrected intermediate visual acuity，UCIVA）、裸眼近距离视力（uncorrected near visualacuity，UCNVA）、最佳矫正远视力（best corrected distance visual acuity，BCDVA）、远视力矫正下的中距离视力（distance corrected intermediate visual acuity，DCIVA）、远视力矫正下的近距离视力（distance corrected near visual acuity，DCNVA），明、暗环境中不同空间频率（3、6、12、18 cpd）下的对比敏感度，并进行脱镜率、不良视觉症状和满意度等问卷调查。采用SPSS16.0统计软件对结果进行统计分析。结果：术后3个月三焦组UCIVA、UCNVA、DCIVA和DCNVA、脱镜率及满意度优于单焦组（P均<0.05）。在明、暗环境中的18 cpd空间频率，单焦组的对比敏感度优于三焦组（P均<0.05）。两组均有轻度眩光和光晕不适主诉，组间差异无统计学意义（P=0.50）。结论：与CT SPHERIS 209M单焦点人工晶状体比较，AT LISA tri 839MP三焦点人工晶体为高度近视患者提供了更好的中、近视力，脱镜率和满意度均高于单焦点人工晶体。
Abstract:
Objective：To compare the visual acuity，contrast sensitivity and visual quality of patients with high myopia after the implantation of AT LISA tri 839 MP multifocal intraocular lens and CT SPHERIS 209M monofocal intraocular 1ens. Methods：Forty-four patients（44 eyes）were involved and divided into two groups in this study. The trail group（22 patients，22 eyes）received AT LISA tri 839MP multifocal intraocular lens implantation and the control group（22 patients，22 eyes）received CT SPHERIS 209M monofocal intraocular lens implantation after phacoemulsification. Parameters including visual acuity，contrast sensitivity at different spatial frequencies（3，6，12，18 cpd）in bright and dark circumstances，independent spectacles ratio，satisfaction and photic phenomena were observed. The post-operative visual acuity included the information of uncorrected distance visual acuity（UCDVA），uncorrected intermediate visual acuity（UCIVA），uncorrected near visual acuity（UCNVA），best corrected distance visual acuity（BCDVA），distance corrected intermediate visual acuity（DCIVA），and distance corrected near visual acuity（DCNVA）. The SPSS 16.0 statistic software was used to analyze the data. Results：The UCIVA，UCNVA，DCIVA，DCNVA，independent spectacles ratio and satisfaction of the trail group were better than those of the control group（all P < 0.05）. The mean contrast sensitivity at spatial frequency of 18 cpd in bright and dark circumstances of the control group was higher than that of the control group（P < 0.05）. The incidence of glare and halo showed no significantly statistical difference between two groups（P=0.50）. Conclusion：AT LISA tri 839MP multifocal intraocular lens provided better intermediate and near vision，higher independent spectacles ratio and more satisfaction of patients than CT SPHERIS 209M monofocal intraocular lens.
