Prediction of cycloplegic refraction for noninvasive screening of children for refractive error.

open access: yesPLoS ONE, 2021
Detection of refractive error in children is crucial to avoid amblyopia and its impact on quality of life. We here performed a retrospective study in order to develop prediction models for spherical and cylinder refraction in children.
