The Ophthalmetron was used to measure the refractive error of 10 male optometry students. Although there was a high incidence of invalid readings, more repeatable results were obtained with use of a cycloplegic. Measurements made under cycloplegia revealed 0.41 D more hyperopia but no differences in astigmatism as compared to the noncycloplegic refraction. Instrument myopia was shown not to be a factor.
使用眼屈光计测量了10名男性验光专业学生的屈光不正情况。尽管无效读数的发生率很高，但使用睫状肌麻痹剂可获得更可重复的结果。与未使用睫状肌麻痹剂的验光结果相比，在睫状肌麻痹状态下进行的测量显示远视多了0.41 D，但散光无差异。结果表明仪器性近视不是一个影响因素。
