Abstract
PurposeTo determine the accuracy of measurement by the Nikon Retinomax handheld autorefractor and its ability to relax accommodation. SettingPediatric Section, Department of Ophthalmology, University of Mainz, Germany. MethodsTo perform a series of comparative measurements, autorefractor readings were obtained on healthy young adults (students) and on children aged 2 to 12 years. The autorefractor readings were compared with subjective refractions of the young adults and with cycloplegic retinoscopy of the children. ResultsIn adults, the accuracy of the handheld autorefractor measurements was comparable to that of conventional tabletop autorefractors. In children, the autorefractor measurements performed under cycloplegia were reliable; when cycloplegic agents were not administered, 24% were overcorrected by more than −2.0 diopters. ConclusionCycloplegia is often necessary to obtain accurate autorefractor results.
