Keratometry and the Central Radius with Aspheric Corneal Surfaces [PDF]
Purpose To develop a simple concept for deriving the central corneal radius (RC) from the keratometry (K) or simulated keratometry (SimK) radius (RS) and corneal asphericity (QC), and to show the differences RC-RS based on a large dataset of ...
