Purpose: To compare the results of different refractive error measurement devices including table-mounted and hand-held autorefractors and videoretinoscopy with cycloplegic retinoscopy (CR) in children to evaluate the usability and reliability of these devices in measuring refractive errors.
Methods: Two hundred eyes of 100 children underwent autorefraction using table-mounted autorefractor with and without cycloplegia and videoretinoscopy after cycloplegia. All results were compared statistically.
Results: The mean spheric values (SV) and spherical equivalent values (SEV) of the non-cycloplegic table-mounted autorefractor were found to be significantly lower and those of the cycloplegic table-mounted autorefractor were found to be significantly higher than CR results. There was no statistically significant difference in terms of mean SV and SEV between the hand-held autorefractor and CR. Although the mean SV using videoretinoscopy were 0.15 diopters lower than CR, this difference was not significant. Comparing CR with the other refraction methods, all devices correlated with each other. Sensitivity in diagnosing myopia was low for all methods but sensitivity in diagnosing hyperopia and astigmatism was high for table-mounted and hand-held autorefractors. The other reliability parameters were found to be similar for all devices.
Conclusions: Both videoretinoscopy and hand-held autorefractor can be used in both screening and examination for children as an alternative to CR and table-mounted autorefractor.

Aim: To evaluate the accuracy, efficiency, and reliability of a handheld infrared eccentric autorefractor (hICA) with artificial intelligence (AI) by comparing its refraction measurements to those recorded using hICA and a clinical table-mounted automatic refractor (TAR).
Methods: A cross-sectional study using three optometers, including hICA with or without AI and TAR, for refractometry of adults (aged 19-49 years old) with no signs of ocular disease or trauma in the absence of cycloplegia. Right and left eye refraction data were recorded, including the spherical equivalent (SE), diopter of spherical power (DS), diopter of cylindrical power (DC) decomposed into vectors J0 and J45, and measurement times.

Background: To compare the refractive results of hand-held and table-mounted autorefractors.
Methods: We designed this study as an observational, cross-sectional study. We compared the mean spheric and cylinder power, spherical equivalent, Jackson cross-cylinder values, determined the limits of agreement (LoA), and evaluated the reliability of two autorefractors.

Objective: To compare the agreement between commercially available table mounted and a hand-held autorefractors and their agreement with subjective refraction. The effect of different body position with the handheld autorefractometer was also evaluated.
Methods: A prospective study was performed on 253 healthy eyes.

Background: To investigate the relationship between dietary intakes at six, nine and 12 months and risk of myopia in three-year-old children in a birth cohort.
Methods: Three hundred and seventeen children from the Growing Up in Singapore Towards Healthy Outcomes (GUSTO) study were included. Dietary intake at six, nine and 12 months of age was ascertained using either 24-hour recalls or three-day food diaries completed by parents.

Objective: To compare the results of the three methods of Suresight handheld autorefractor, table-mounted autorefractor and retinoscopy in examination of juveniles patients with or without cycloplegia.
Methods: Firstly, 156 eyes of 78 juveniles (5 to 17 years old) were examined by using WelchAllyn Suresight handheld autorefractor and NIDEK ARK-510A table-mounted autorefractor with or without cycloplegia; secondly, retinoscopy was performed with cycloplegia.
Results: The spherical power measured by methods without cycloplegia were significantly greater than those measured with cycloplegia (P<0.
