Absolute accuracy of Placido-based videokeratographs to measure the optical aberrations of the cornea.

Abstract

Advances in excimer laser spot size and ablation pattern capabilities, together with the development of Hartmann-Shack sensors for high-resolution eye aberration measurements, have taken refractive surgery to a new stage. Nevertheless, studies have shown that the lens contributes differently to total aberration and depends on accommodation and age factors… (More)
