The variations of refractive errors during both hard, hydrophilic and silicone lens wear were significantly correlated in the 2 eyes of each individual. In each lens group the mean changes of spherical and cylindrical refractive errors were small (-0.458D-+0.250D and -0.325D-+0.056D, respectively). Considerable individual refractive changes occurred (spherical change: -3.0D-+1.5D, cylindrical change: -2.5D-+1.0D). However, only 2 subjects noticed spectacle blur and a normal visual acuity was always obtained by spectacle refraction immediately after lens removal. This indicated that clinically significant distortion of the central cornea did not take place. Hydrophilic lens wearers showed an increasing myopia during lens wear. Otherwise the refractive changes were not significantly influenced by the duration of lens wear. Refractive changes appeared to be significantly correlated to changes of the central anterior corneal curvature, the ratio of dioptric changes being about 1:1.
在每个个体的双眼佩戴硬性亲水镜片和硅水凝胶镜片期间，屈光不正的变化显著相关。在每个镜片组中，球镜和柱镜屈光不正的平均变化较小（分别为-0.458D至+0.250D和-0.325D至+0.056D）。出现了相当大的个体屈光变化（球镜变化：-3.0D至+1.5D，柱镜变化：-2.5D至+1.0D）。然而，只有2名受试者注意到眼镜视物模糊，且在摘除镜片后立即通过眼镜验光总能获得正常视力。这表明中央角膜未发生具有临床意义的变形。亲水镜片佩戴者在佩戴镜片期间近视度数增加。此外，屈光变化不受镜片佩戴时间的显著影响。屈光变化似乎与中央角膜前表面曲率的变化显著相关，屈光度变化的比例约为1:1。
