Scleral shape and its correlation with corneal parameters in keratoconus.

Purpose: To assess the correlation of the scleral shape and corneal tomographic parameters in keratoconus.

Methods: Twenty eyes of 15 keratoconus patients with no previous specialty lens wear or ocular surgery were included in this study. Corneal imaging was obtained with the Pentacam HR and three-dimensional (3D) corneoscleral maps were acquired using the Eye Surface Profiler, ESP.
