A combination of human subject data and optical modelling was used to investigate unexpected nasal-temporal asymmetry in peripheral refraction with an aspheric myopia control lens. Peripheral refraction was measured with an auto-refractor and an aberrometer. Peripheral refraction with the lens was highly dependent upon instrument and method (e.g. pupil size and the number of aberration orders). A model that did not account for on-eye conformation did not mirror the clinical results, but a model assuming complete lens conformation to the anterior corneal topography accounted for the positive shift in clinically measured refraction at larger nasal field angles. The findings indicate that peripheral refraction of highly aspheric contact lenses is dependent on lens conformation and the method of measurement. These measurement methods must be reported, and care must be used in interpreting results.
结合人体受试者数据和光学建模，研究了非球面近视控制镜片周边屈光中意外的鼻侧 - 颞侧不对称性。使用自动验光仪和像差仪测量周边屈光。佩戴该镜片时的周边屈光高度依赖于仪器和方法（例如瞳孔大小和像差阶数）。一个未考虑眼上形态的模型无法反映临床结果，但一个假设镜片完全贴合前角膜地形图的模型能够解释在较大鼻侧视野角度下临床测量的屈光正向偏移。研究结果表明，高非球面隐形眼镜的周边屈光取决于镜片形态和测量方法。必须报告这些测量方法，并且在解释结果时要谨慎。
