Table 1 Tomographic parameters derived from Pentacam

From: Comparisons of corneal biomechanical and tomographic parameters among thin normal cornea, forme fruste keratoconus, and mild keratoconus

Parameters Means
KmF Mean keratometry from the anterior corneal surface
Kmax Maximum keratometry from the anterior corneal surface
Astig F Central astigmatism from the anterior corneal surface
ISV Index of surface variance
IVA Index of vertical asymmetry
KI Keratoconus index
CKI Central keratoconus index
IHA Index of height asymmetry
IHD Index of height decentration
