There is no apparent association between age and either apical radius or p-value for the subjects used in this study. The asphericity of the cornea does not show any apparent association with corneal curvature in this group of subjects. 展开 ...
1. A method of modeling a cornea, comprising: measuring a radius of curvature of a cornea; converting said measured radius to an apical radius; and fitting an ellipsoid to said cornea based on said apical radius. 2. The method of modeling a cornea according to claim 1, wherein: said ...

generated by syncheronizing with travelling is counted extending from the full line position of the slit screen 3 detected by the detector 6 to the virtual line position detected by the detector 6', and by this count value, the radius of curvature of the cornea is measured as a digital ...
We have developed an automatic optical system attached to the Slit Lamp in order to provide automatic measurements of the radius of curvature of the cornea at low cost. The system consists of projecting a light ring as a target at the patient's cornea and the further analysis of the ...
