&NA;利用超声和摄影晶状体测量技术对二十名儿童的双眼进行了五次独立的眼部屈光度测量，首先在非睫状肌麻痹条件下，然后在一小时后在睫状肌麻痹条件下进行。在睫状肌麻痹下进行的角膜屈光度和超声测量的方差与在未加固状态下进行的测量的方差没有显著差异。因此，通过实验未发现通过使用睫状肌麻痹剂实现的可靠性的假设改善。在非睫状肌麻痹状态下测定的右眼和左眼眼成分值的有效性均显著高于睫状肌麻痹状态。
&NA; A comparison of five independent measurements of the ocular dioptric components utilizing both ultrasonic and photographic phakometric techniques was made on both eyes of twenty children under first non‐cycloplegic and then one hour later, cycloplegic conditions. The variances for both the phakometric and ultrasonic measurements made under cycloplegia were not significantly different from those made in the undrugged state. Thus, the hypothesized improvement in reliability accomplished through the use of cycloplegia was not found experimentally. Both right and left eye ocular component values determined in the non‐cycloplegic state were shown to have significantly higher validity than those for the cycloplegic state.
