Galilei topographic map. Asphericity asymmetry index (AAI)-difference between maximum negative best-fit toric aspheric (BFTA) reference& maximum positive BFTA elevation. Keratoconus prediction index (KPI)-probability of keratoconus by analyzing anterior corneal topographic data. Cone location &magnitude index (CLMI)-steepest area of curvature & magnitude represents difference between steepest area from remainder of the curvature map. Keratoconus Probability (Kprob)-sensitivity & specificity of reported KPI. Percentage probability of keratoconus (PPK)-optimal threshold for detecting keratoconus
