Abstract

David A Atchison,1,2 Andreas Hartwig3 1School of Optometry and Vision Science, 2Institute of Health and Biomedical Innovation, Queensland University of Technology, Brisbane, QLD, Australia; 3Hartwig Research Center, Heikendorf, Germany We read with interest the article entitled ‘Population spherical aberration: associations with ametropia, age, corneal curvature, and image quality’ by Kingston and Cox.1 The authors provided higher order aberrations data for a sample of 1,124 eyes and performed correlation analyses to compare higher order aberrations with refraction and biometry data, such as spherical equivalent power and corneal curvature. Special attention was drawn to spherical aberration.View original paper by Kingston and Cox.
