Keratorefractive indices
fig. 1-28
Tap on the ”I” button to view the keratorefractive indices (fig. 1-28):
3 and 5 mm astigmatism
Average pupillar power for a 4.5 mm pupil
Asphericity of an 8mm diameter cornea
Longitudinal spherical aberration of a 4.5 mm diameter cornea area
Curvature irregularity calculated on the standard deviation of the instantaneous values
for a 4.5 mm cornea area
Asymmetry between the most curved and the flattest hemisphere calculated for a 4.5
mm diameter cornea area
SAI (Surface Asymmetry Index) represents the surface asymmetry index of a 4.5 mm
diameter cornea area
