Clinical refractive data were obtained on 32 subjects by each of three examiners, each examiner using standard subjective refraction procedures with an endpoint criterion of "maximum plus for best visual acuity." The results of the three examiners were compared in terms of spherical equivalent refraction, spherical power, cylinder power, cylinder axis, and anisometropia. In addition, results were compared to those of previous studies involving both clinical refraction and the American Optical Corporation's SR III Subjective Refraction System.
三名检查者分别对32名受试者进行了临床屈光数据测量，每名检查者均采用标准主观验光程序，以“最佳视力下最大正度数”作为终点标准。比较了三名检查者在等效球镜度、球镜度数、柱镜度数、柱镜轴位和屈光参差方面的结果。此外，还将结果与之前涉及临床验光和美国光学公司SR III主观验光系统的研究结果进行了比较。
