Saad and Gatinel recently stated that one index alone can hardly reach a high sensitivity and specificity in the detection of forme fruste keratoconus or ectasia-susceptible corneas.1'2 In their study, they described and compared topography and tomography indices, as well as the central to periphery percentage of thickness increase and the percentage of anterior and posterior curvature modification in three groups of corneas classified as. normal (LASIK with 2-year follow-up), forme fruste keratoconus, and keratoconus by specular topography, on the basis of the artificial intelligence of the Corneal Navigator (NIDEK Co Ltd, Gamagori, Japan), and combined those indices in discriminant functions to detect mild ectatic corneas.
