- TNC thin normal cornea; FFKC forme fruste keratoconus; MKC mild keratoconus; CCT central corneal thickness; TCT thinnest corneal thickness; bIOP biomechanically corrected intraocular pressure
- P value is for differences between the three groups, #represents statistically significant difference with TNC and MKC
