Abstract:To evaluate the repeatability of wavefront aberration measurements and the correlation between corneal aberration and pupil size in normal eyes using a wavefront-based autorefractor (i.Pro ler Plus ; Carl Zeiss Vision, Germany).
MethodsA prospective cross-sectional study. Wavefront aberrations, including SA (Z 4 0 ), coma (Z 3 − 1 , Z 3 1 ), trefoil (Z 3 − 3 , Z 3 3 ) and total higher-order aberrations (tHOA), were measured at different pupil diameters. The repeatability was evaluated using one-way ANOVA metho… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
