方法用Haag-Streit角膜曲率计测量角膜前表面曲率半径。垂直子午线上的角膜切片照片与包含顺序不同半径的曲线的网格相匹配。角膜后表面的摄影曲率半径通过斜光线追踪和适当的计算机程序转换为真实曲率半径（Clark和Lowe，1973）。之前已发表了更多临床详情（Lowe，1972）。通过这种技术，可以在垂直子午线上测量以5毫米弦为中心的曲面。
Method The radius ofcurvature of the anterior corneal surface was measured with a Haag-Streit keratometer. Photographs of corneal sections in the vertical meridian were matched against graticules containing curves of sequentially differing radii. Photographic radius of curvature of the posterior corneal surface was converted to true radius ofcurvature by skew ray tracing and an appropriate computer programme (Clark and Lowe, 1973). Further clinical details have been published previously (Lowe, 1972). By this technique, curved surfaces centred over a 5-mm. chord could be measured in the vertical meridian.
