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.

非球面近视控制隐形眼镜的周边折射时空不对称

使用人类受试者数据和光学模型的组合来研究非球面近视控制透镜在周边屈光方面的意外鼻-颞不对称。用自动折射仪和像差计测量周边折射。晶状体的周边折射在很大程度上取决于仪器和方法（例如，瞳孔大小和像差级数）。未解释眼部构象的模型未反映临床结果，但假设完全晶状体构筑至角膜前部地形的模型解释了在较大的鼻视野角处临床测量的屈光度的正向偏移。研究结果表明，高度非球面隐形眼镜的周边折射取决于镜片的构造和测量方法。这些测量方法必须报告，
