Should the Corvis Biomechanical Index (CBI) Include Corneal Thickness Parameters?

We read with great interest the article by Steinberg et al.1 regarding a modified Corvis Biomechanical Index (named aCBI in the article) with the elimination of corneal thickness data, including the Ambr ósio's Relational Thickness in the horizontal profile (ARTh). The aim of the cited article was to provide a proof of concept of whether corneal deformation (biomechanics) alone would be sufficient to separate normal patients from patients with keratoconus.1 This was accomplished by creating the aCB I algorithm without the ARTh in a pairwise matching of normal and keratoconic eyes with regard to
