摘要 评估眼部屈光成分的超声波方法提供了观察到的眼轴长度，但没有关于晶状体表面屈光力的数据。多年来，晶状体测量方法一直在提供晶状体表面的完整数据输出，并依赖于眼轴长度的计算值；然而，鉴于当今的技术，后者的有效性受到了挑战。提出了一系列方程，其中将两种技术结合起来，以克服对眼影测量的一些反对意见，同时不仅保留晶状体数据，而且还包括眼睛光学系统的基点。
ABSTRACT The ultrasonic method of assessing the ocular components of refraction provides an observed axial length but no data on the lens surface powers. For many years the phakometric methods have been supplying a full data output on the lens surfaces and relying on a computed value for the axial length; the validity of the latter, however, has been challenged in the light of present‐day techniques. A series of equations are presented in which the two techniques are combined to overcome some of the objections to phakometry yet maintain not only the lens data but also include the cardinal points of the eye optical system.
