The gender distribution was presented as male/female (χ2-test). Continuous data were expressed as mean ± SD for normally distributed data (t-test) or median [IQR] for non-normally distributed data (Mann–Whitney U test). LVC = laser vision correction; KC = keratoconus; CCT = central corneal thickness; TCT = thinnest corneal thickness; Kmax = maximum K value; BAD-D = Belin-Ambrosio Display D value; IS-value = inferior–superior value; KI = keratoconus index; PRFI = Pentacam random forest index; CBI = Corvis biomechanical index; TBI = tomographic and biomechanical index; SSI = stress–strain index.
