To measure corneal curvature in newborn infants and patients in the supine position, we rearranged an automated keratometer, dividing it into two parts, the power unit and the measuring system. The measuring unit was mounted on a universal stand. We observed no difference in measured value between the sitting and supine positions and no difference in maneuverability. We also examined the effect of a speculum in normal adult subjects in the supine position, in which both the strong and the weak radii and the axis of astigmatism were slightly affected. However, there was no significant difference in the mean values of the strong and weak radii of corneal curvature in 22 eyes of infants with corrected gestational ages of 37 to 43 weeks. The examination was carried out with ease. The mean value of corneal curvature was 7.05 mm and the range was 6.63 to 7.74 mm.
为测量新生儿及仰卧位患者的角膜曲率，我们对自动角膜曲率计进行了改装，将其分为两部分，即动力单元和测量系统。测量单元安装在通用支架上。我们发现坐位和仰卧位的测量值无差异，操作灵活性也无差异。我们还检查了在仰卧位正常成年受试者中使用开睑器的效果，其中强、弱半径及散光轴均受到轻微影响。然而，在胎龄矫正至37至43周的22只婴儿眼中，角膜曲率强、弱半径的平均值无显著差异。检查操作轻松。角膜曲率平均值为7.05毫米，范围为6.63至7.74毫米。
