Scheimpflug camera measurement of anterior and posterior corneal curvature in eyes with previous radial keratotomy.

Abstract

After RK, both corneal surfaces flatten but do not deform in parallel as commonly accepted, as shown by the fact that the anterior-to-posterior corneal curvature ratio decreases.

This finding invalidates the standard keratometric index and thus has relevant implications for intraocular lens power calculation in RK eyes.
