Peripheral refraction, relative peripheral refraction, and axial growth: 18‐month data from the randomised study—Clinical study Of Near‐sightedness; <scp>TReatment</scp> with Orthokeratology Lenses (<scp>CONTROL</scp> study)

Abstract

We found no correlations between change in RPR and treatment efficacy defined as change in AL. Interestingly, our results suggest that the central emmetropisation that occurs during OKL-use accounts for most of the optical changes and to a lesser extent the mid-peripheral plus-zone of the lens.
