Abstract
We developed a formula to measure the posterior curvature of the cornea. In our study, real corneal power in 51 eyes was calculated by using anterior and posterior curvatures and corneal thickness. The corneal refractive index was found to be a variable value between 1.3243 and 1.3339 (mean 1.3304 +/- 0.0003).
摘要
我们开发了一种测量角膜后表面曲率的公式。在我们的研究中，通过使用前、后表面曲率以及角膜厚度计算了51只眼睛的实际角膜屈光力。发现角膜折射率在1.3243至1.3339之间变化（平均值为1.3304±0.0003）。
