A new refraction system employing traditional modes of testing combined with microprocessor-based electronics and new optical technology was evaluated in a controlled study to determine if the instrument produced subjective refractions corresponding to the traditional refractor. Subjects ranged in age from 14 to 25 years and the study excluded any individual exhibiting ocular or systemic diseases and binocular problems. In addition, tests were made to determine if "instrument myopia" was present. The results showed that data from the IVEX Refraction System correlated highly with data from the standard refractor, but a small amount (0.25 D to 0.37 D) of instrument myopia was present in most instances.
在一项对照研究中，对一种采用传统测试模式并结合基于微处理器的电子设备和新光学技术的新型验光系统进行了评估，以确定该仪器所产生的主观验光结果是否与传统验光仪相符。受试者年龄在14至25岁之间，该研究排除了任何患有眼部或全身性疾病以及双眼问题的个体。此外，还进行了测试以确定是否存在“仪器性近视”。结果表明，IVEX验光系统的数据与标准验光仪的数据高度相关，但在大多数情况下存在少量（0.25 D至0.37 D）的仪器性近视。
