To evaluate the impact of eye and head rotation in the measurement of peripheral refraction with an open-field autorefractometer in myopic eyes wearing two different center-distance designs of multifocal contact lenses (MFCLs).
Nineteen right eyes from 19 myopic patients (average central M ± SD = -2.67 ± 1.66 D) aged 20-27 years (mean ± SD = 23.2 ± 3.3 years) were evaluated using a Grand-Seiko autorefractometer. Patients were fitted with one multifocal aspheric center-distance contact lens (Biofinity Multifocal D(®)) and with one multi-concentric MFCL (Acuvue Oasys for Presbyopia). Axial and peripheral refraction were evaluated by eye rotation and by head rotation under naked eye condition and with each MFCL fitted randomly and in independent sessions.
For the naked eye, refractive pattern (M, J0 and J45) across the central 60° of the horizontal visual field values did not show significant changes measured by rotating the eye or rotating the head (p > 0.05). Similar results were obtained wearing the Biofinity D, for both testing methods, no obtaining significant differences to M, J0 and J45 values (p > 0.05). For Acuvue Oasys for presbyopia, also no differences were found when comparing measurements obtained by eye and head rotation (p > 0.05). Multivariate analysis did not showed a significant interaction between testing method and lens type neither with measuring locations (MANOVA, p > 0.05). There were significant differences in M and J0 values between naked eyes and each MFCL.
Measurements of peripheral refraction by rotating the eye or rotating the head in myopic patients wearing dominant design or multi-concentric multifocal silicone hydrogel contact lens are comparable.
评估在佩戴两种不同中心距设计的多焦点隐形眼镜（MFCL）的近视眼中，眼球和头部转动对使用开放式自动验光仪测量周边屈光的影响。
使用Grand - Seiko自动验光仪对19名年龄在20 - 27岁（平均±标准差 = 23.2 ± 3.3岁）的近视患者的19只右眼（平均中央屈光度M±标准差 = -2.67 ± 1.66 D）进行评估。患者分别佩戴一副多焦点非球面中心距隐形眼镜（Biofinity Multifocal D(®)）和一副多同心MFCL（Acuvue Oasys for Presbyopia）。在裸眼条件下以及每次随机且独立佩戴每种MFCL时，通过眼球转动和头部转动评估轴向和周边屈光。
对于裸眼，在水平视野中央60°范围内的屈光模式（M、J0和J45），通过转动眼球或转动头部测量时未显示出显著变化（p > 0.05）。佩戴Biofinity D时，两种测试方法均得到类似结果，M、J0和J45值无显著差异（p > 0.05）。对于Acuvue Oasys for presbyopia，比较通过眼球和头部转动获得的测量结果时也未发现差异（p > 0.05）。多变量分析未显示测试方法与镜片类型之间以及与测量位置之间存在显著交互作用（多变量方差分析，p > 0.05）。裸眼与每种MFCL的M和J0值之间存在显著差异。
在佩戴主导设计或多同心多焦点硅水凝胶隐形眼镜的近视患者中，通过转动眼球或转动头部测量周边屈光的结果具有可比性。
