Significant difference was bold.
Steep-K: keratometry along the steepest meridian; Flat-K: keratometry along the flattest meridian; Steep-Q: asphericity along the steepest meridian; Flat-Q: asphericity along the flattest meridian; CH: corneal hysteresis; CRF: corneal resistance factor; S: corneal stiffness; EN: normalized corneal tangent modulus.
