Abstract

The theoretical basis for the calculation of corneal refractive power from anterior curvature is considered. It is shown that the power can be calculated with sufficient accuracy from one simple formula provided the refractive index of the 'cornea' is 1.3315. It is suggested that keratometer readings should be calibrated with this value in order to increase the accuracy in intraocular lens calculation.

摘要

本文探讨了根据角膜前表面曲率计算角膜屈光力的理论基础。研究表明，若“角膜”的折射率为1.3315，可通过一个简单公式足够准确地计算出屈光力。建议用该值对角膜曲率计读数进行校准，以提高人工晶状体计算的准确性。
