目的 研究白内障超声乳化吸除术植入不同非球面性人工晶状体(intraocular lens,IOL)对垂直慧差(vertical coma aberrations)的影响.方法 前瞻性研究.选取天津眼科医院2010～2011年单纯性老年性白内障患者116只眼,随机分成4组,31只眼植入球面IOL Sensar AR40e,29只眼植入零球差IOL Akreos AO,25只眼植入零球差IOL Softec HD,31只眼植入负性非球面IOL Tecnis ZA9003.术后3～4个月随访,使用iTrace像差仪采集患者在5.0 mm瞳孔下的垂直慧差,水平慧差,球差的均方根(root mean square,RMS).应用Pentacam三维眼前段分析仪测量IOL的倾斜度与偏心量.比较各组间的垂直慧差,水平慧差和球差以及垂直慧差与IOL的倾斜度和偏心量之间的关系.结果 垂直慧差和球差在球面IOL组最高,零球差IOL组次之,负性非球面IOL组最低(F=7.276,P=0.000;F=107.2,P=0.000).水平慧差在各组间差异无统计学意义(P＞0.05).4组垂直慧差与IOL的倾斜度和偏心量的相关性无统计学意义(P＞0.05).结论 IOL的非球面性变化导致垂直慧差的改变,IOL一定限度内的倾斜和偏心对垂直慧差的影响很小.球面IOL与非球面IOL相比能诱导更多的垂直慧差,从而有助于改善术后近视力和阅读能力.

Objective To analyze the effect of asphericity of intraocular lenses (IOLs) on vertical coma aberration after phacoemulsification surgery and IOLs implantation. Methods It was a prospective clinical study.A total of 116 eyes of 78 patients were with IOLs implantation and 3 to 4 months after surgery was analyzed in this study,including 31 eyes with spherical IOL of Sensar AR40e,54 eyes with aspheric aberration-free IOLs of Akreos AO (29 eyes) and Softec HD (25 eyes) and 31 eyes with aspheric IOL of Tecnis ZA9003 with negative spherical aberration.At postoperative follow-up visits,maximum pupil dilation was achieved and aberrometry was performed using an iTrace aberrometer with a pupil scan size of 5.0 mm.Data on vertical coma,horizontal coma,and spherical aberration were extracted.Tilt and decentration of the IOLs were measured using Scheimpflug photography (Pentacam,Oculus) and analyzed with Image-Pro Plus 6.0 software. Results Vertical coma and spherical aberration values were highest with the spherical IOLs and lowest with the aspheric IOLs (P =0.000 and P =0.000,respectively).There was no difference in horizontal coma aberration between the 4 IOL groups.There was no correlation between tilt,decentration and vertical coma aberration (P ＞0.05). Conclusions Conventional spherical IOLs induce more vertical coma than aspheric IOLs and may help uncorrect near vision.
