The table provides mean ± sem values of the corneal thickness and corneal deformation assessed using Corvis-ST. K1, K2: Independent readings of corneal curvature by keratometry; Km and K-Max: Mean keratometry value and maximum keratometry value respectively. MRSE: Manifest refraction spherical equivalent, TCT: Thinnest Corneal Thickness; BAD D index is a measure of severity of keratoconus. The ANOVA p value column shows group statistics; pair wise statistics explained in the results section.
