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… CONTINUE READING
