Visual acuity, manifest refraction, topography, specular . Topographic parameters assessed included: maximum keratometry (Kmax), steep keratometry (Ksteep), flat keratometry (Kflat), inferior-superior (I-S) ratio and the surface asymmetry and regularity (surface asymmetry index and surface regularity index) indices. In these cases, piggyback lenses may be used. Epub 2016 Sep 27. 7. TT McMahon et al., Longitudinal changes in corneal curvature in keratoconus, Cornea, 25, 296 (2006).
