The repeatability and accuracy of an i.r. electronic optometer (the Ophthalmetron) and of retinoscopy performed by experienced practitioners were studied in aphakia by testing a group of 17 patients three times with each method and by subjective techniques. The results show that the Ophthalmetron gives better repeatability than retinoscopy and that accuracy is marginally better for the sphere with the Ophthalmetron and for the cylinder power by retinoscopy when the mean of the three subjective results is taken as the true refractive value.
通过用红外电子验光仪（Ophthalmetron）和经验丰富的从业者进行检影验光，对一组17例无晶状体患者分别用这两种方法进行三次测试，并采用主观验光技术，研究了这两种方法的重复性和准确性。结果表明，与检影验光相比，Ophthalmetron具有更好的重复性，并且当将三次主观验光结果的平均值作为真实屈光值时，Ophthalmetron在球镜度数方面的准确性略好，检影验光在柱镜度数方面的准确性略好。
