Theoretical model demonstrates conversion of keratometric radius to central radius, suggesting clinical relevance in corneal assessments.
For corneal representations with a conoid surface or where central corneal radius is required e.g. for paraxial calculations, the keratometric radius of curvature could easily be converted to the central radius based on corneal asphericity and the keratometric zone diameter. With large positive or negative values of QC the differences RC-RS could be clinically relevant.
