Abstract
The relationship between corneal curvature measured by classical keratometry and refractive error raises the question of a possible systematic relationship between refractive error and the degree of corneal asphericity. A recomputation and analysis of previously published data leads to the conclusion that the different refractive groups have similar values of the parameter ‘p’ and differ only in the apical radius of the cornea.This publication has 3 references indexed in Scilit:
