摘　　要：目的 观察消像差程序飞秒激光制瓣的准分子激光原位角膜磨镶术（FS-LASIK）矫正近视和近视散光效果.方法 前瞻性研究.2013年12月至2014年8月接受阿玛仕消像差程序矫正近视和近视散光76例（76只眼）,均以右眼为研究对象.其中包括中低度近视和近视散光37只眼（低于-6.0D）和高度近视和近视散光39只眼（-6.0D及以上）.术前和术后分别应用Optikon 2000角膜波阵面像差分析仪检查角膜高阶像差均方根值,其中包括球差、彗差和所有高阶像差总均方根值.随访3个月.结果 术后3个月角膜球差、彗差和总的高阶像差与术前比较,差异均无统计学意义（t=1.999,1.508,1.435;P =0.053,0.080,0.075）;中低度近视和近视散光者角膜高阶像差均方根值与术前比较,差异均无统计学意义（t=1.530,1.774,2.053;P=0.120,0.080,0.052）;高度近视和近视散光者角膜高阶像差均方根值均高于术前,差异有统计学意义（=3.408,5.372,2.829;P=0.005,0.000,0.005）.低中度近视和近视散光者高阶像差增加较高度近视和近视散光者少.结论 阿玛仕消像差程序能有效减少FS-LASIK术后高阶像差的增加,特别是矫正中低度近视和近视散光.Objective To observe the efficacy of aberration elimination program in femtosecond assisted situ keratomileusis （FS-LASIK）for the correction of myopia and myopic astigmatism.Methods A prospective study.From Dec.2013 to Aug.2014,76 eyes of 76 cases with myopia and myopic astigmatism received aberration elimination program FS-LASIK.The right eye was the object of study.There were 37 eyes of low to moderate myopia and myopic astigmatism （〈-6.0D） and 39 eyes of high myopia and myopic astigmatism（≥-6.0D）.The Optikon 2000 corneal wavefront aberration analyzer was used to examine the corneal higher-order aberrations before and 3 months after surgery.The corneal higher-order aberrations included spab,coma and total higher-order aberrations.Results The difference of spherical aberration,coma and total higher-order aberrations were not statistically significant between before and 3 months after surgery （t =1.999,1.508,1.435;P =0.053,0.080,0.075）.The difference of corneal higher-order aberration of patients with low to moderate myopia and myopic astigmatism were not statistically significant between before and 3 months after surgery （t =1.530,1.774,2.053;P =0.120,0.080,0.052）.The difference of the corneal higher-order aberrations of patients with high myopia and myopic astigmatism between before and 3 months after surgery were statistically significant （t =3.408,5.372,2.829;P =0.005,0.000,0.005）.The variational ratio and multiple of higher-order aberrations in low to moderate myopia and myopic astigmatism were less than that in high myopia and myopic astigmatism.Conclusion The aberration elimination program can effectively reduce the higher-order aberrations especially in low to moderate myopic astigmatism after FS-LASIK.
