Is Objective Refractive Data The Entire Equation?

Wavefront, standard and Placido topographic ablations attempt to directly compensate for the refractive error of the eye under the assumption that there is no need to know corneal morphology.
CIPTA states that the refractive process is the natural consequence of the morphology of the surfaces. The refractive process is generated by the morphology of the surface and not visa-versa!

$CIPTA uniquely uses a synthesis of high definition elevation, refractive, and dynamic pupillometry data.$

Wavefront, standard and Placido topographic ablations apply a lens to the cornea to compensate for the refractive error.
To optimize the patient's quality of vision, CIPTA regularizes the anterior surface of the cornea by means of the identification and location of the ideal shape. The refractive correction is the natural consequence of the corneal regularization.
Wavefront measurements at best provide data only in the pupil area with no information as to how to best shape an optimized transition zone from the optical correction.
As the irregularity of the cornea increases, wavefront measurements may become less repeatable or may not be acquired at all.
Wavefront data may erroneously treat certain conditions exaggerating the original problem (see Strategic Planning in Topography-guided Ablation of Irregular Astigmatism After Refractive Surgery, Aleksander Stojanovik, MD; Dasa Suput, MD. Journal of Refractive Surgery, Vol 21, July/August 2005).
