SIf: symmetry index front; D: diopter; KVf: keratoconus vertex front; μm: micron; SIb: symmetry index back; KVb: keratoconus vertex back; BCV: Baiocchi Calossi Versaci index (total); [95% CI]: 95% confidence interval. Statistically significant increased values . The value in bold is statistically significant.
