The aims of the study were (1) to compare the accuracy and intrasession variability of noncycloplegic autorefraction (AR) obtained by a photorefractor and conventional and open-field autorefractors and (2) to evaluate the impact of accommodative and binocular vision anomalies on the accuracy of autorefraction. Twenty-nine children and adolescents aged 8-18 years were examined. All instruments gave more myopic results than subjective refraction (SR). Mean differences between the SR and the AR were +0.52/-0.25×96 for the photorefractor, +0.63/-0.31×93 for the conventional autorefractor, and +0.19/-0.26×94 for the open-field instrument. The photorefractor appeared to be the most repeatable. The impact of the examined vision anomalies on the accuracy of autorefraction was not statistically significant.
(1) 比较光反射仪和传统及开放视野自动验光仪在非睫状肌麻痹下自动验光的准确性和日内可变性；(2) 评估调节和双眼视觉异常对自动验光准确性的影响。共检查了 29 名 8-18 岁的儿童和青少年。所有仪器的检查结果均比主观验光（SR）更近视。光反射仪与 SR 之间的平均差异为+0.52/-0.25×96，传统自动验光仪为+0.63/-0.31×93，开放视野仪器为+0.19/-0.26×94。光反射仪的重复性似乎最好。检查的视觉异常对自动验光准确性的影响没有统计学意义。
