The corneal morphology was evaluated using two techniques, Pentacam and SD-OCT. Pentacam provided measurements of mean keratometry from the anterior corneal surface (Km F), mean keratometry from the posterior corneal surface (Km B), max keratometry from the anterior corneal surface (Kmax F), CCT, posterior corneal elevation (PCE), index of surface variance (ISV), index of vertical (IVA), index of height decentration (IHD) and the corneal volumes at 3, 5, 7, and 10 mm (C. Vol D 3 mm, C. Vol D 5 mm, C. Vol D 7 mm, and C. Vol D 10 mm respectively). The overall CCT and corneal epithelial thickness (CET) were measured by SD–OCT.
