Fig. 2From: Comparisons of corneal biomechanical and tomographic parameters among thin normal cornea, forme fruste keratoconus, and mild keratoconusDifferences between the three groups with respect to IHA (a) and IHD (b). *, # and &represent statistically significant differences between TNC and FFKC, TNC and MKC, and FFKC and MKC, respectively. IHA, index of height asymmetry; IHD, index of height decentration; TNC, thin normal cornea; FFKC, forme fruste keratoconus; MKC, mild keratoconusBack to article page
