KERATOCONUS, CORNEAL DISEASES
The corneal thickness and location data has less variability for the CASIA, compared to the Pentacam, in both repeatability and reproducibility. The CASIA corneal thickness measurements are also consistently lower in value than the Pentacam corneal thickness measurement in every point in the periphery: PCT2, PCT4, and PCT6. The pattern/distribution of corneal thickness (pachymetry map) and the location of the thinnest point in the corneal is important in planning for refractive surgery and detecting corneal diseases, such as keratoconus [
