Cycloplegic Autorefraction Results in Pre-School Children Using the Nikon Retinomax Plus and the Welch Allyn SureSight

Abstract

Even though the Retinomax Plus and the SureSight appear to agree with each other and with the results of cycloplegic retinoscopy for determining sphere and cylinder power, interpretation of the data should be considered as screening only because the actual magnitude of sphere and cylinder may vary from the actual magnitude. These results suggest that either device may be useful only as screening tools for assessing refractive error in pre-school children.
