【摘要】：目的:比较植入REZOOM、Acri.Lisa366D和Tecnis ZMA00三种不同特性多焦点人工晶状体的术后视觉质量。方法:选取2008年9月～2010年3月期间,在天津市眼科医院白内障中心行白内障超声乳化术联合多焦点人工晶状体植入术患者,分别植入REZOOM、Acri.Lis、Tecnis ZMA00。术后随诊复查,进行问卷调查视觉质量,以Colenbrander Mixed Contrast Card Set视力测试卡分别测量高/低对比度条件下,最佳矫正远视力下的中、近视力。以iTrace视觉功能分析仪检查得出5、10、15、20、25、以及30cpd空间频率的调制传递函数(MTF)、眼内像差及瞳孔直径。以iTrace3.12软件分析3种人工晶状体眼在4mm瞳孔直径下的MTF。结果:三组最佳矫正远视力比较,差异无统计学意义(P0.05)。最佳矫正远视力下的中视力,三组在高对比度条件下比较,差异有统计学意义(P0.05),REZOOM低于另2组;低对比度条件下比较,3组差异无统计学意义(P0.05)。最佳矫正远视力下的中视力3组在高/低对比度条件下比较,差异无统计学意义(P0.05)。3组调制传递函数在4mm瞳孔直径下比较,在5cpd、10cpd、15cpd、20cpd间频率下的差异有统计学意义(P0.05)。眼内像差三组间差异有统计学意义(P0.05)。结论:三种多焦点人工晶状体术后在远视力方面表现优秀且差异不大,在中距离视力和近视力方面也都有良好表现,但同时也体现出了一定的差异。而术后的视觉症状如眩光、光晕等三种人工晶状体没有出现对生活的影响。对于调制函传递数的表现,作为非球面多焦点人工晶状体的Acri.Lisa366D和Tecnis ZMA00表现优于球面设计的REZOOM。
[Abstract]:Objective: to compare the postoperative visual quality of rezommonus Acri.Lisa 366D and Tecnis ZMA00.Methods: from September 2008 to March 2010, patients underwent cataract phacoemulsification combined with multi-focus intraocular lens implantation in the Center of Cataract, Tianjin Ophthalmology Hospital.The visual quality was investigated with Colenbrander Mixed Contrast Card Set visual acuity test card. The middle and near visual acuity of the best corrected far visual acuity was measured under the condition of high / low contrast.The iTrace visual function analyzer was used to detect the 30cpd spatial frequency, the modulation transfer function (MTF), the intraocular aberration and the pupil diameter.The MTF of three kinds of intraocular lens under the pupil diameter of 4mm were analyzed by iTrace3.12 software.Results: there was no significant difference in the best corrected far visual acuity among the three groups (P 0.05).Under the best corrected far visual acuity, the difference between the three groups under the condition of high contrast was statistically significant, and the difference of REZOOM between the three groups was lower than that in the other two groups, but there was no significant difference among the three groups under the condition of low contrast.The difference of intraocular aberration among the three groups was statistically significant (P 0.05).Conclusion: the three kinds of multifocal intraocular lens have excellent and little difference in far visual acuity and good performance in middle distance vision and near visual acuity, but also show some differences.The postoperative visual symptoms such as glare, halo and other three kinds of intraocular lens did not affect life.For the performance of modulation function transfer number, Acri.Lisa366D and Tecnis ZMA00, as aspheric multi-focus intraocular lens, are better than the spherical design REZOOM.
