Purpose : The clinical usefulness of handheld photo-refractor evaluation using objective refraction to compare the refractive error in children was measured with table auto-refractor, retinoscope and handheld photo-refractor.

Methods : The refractive errors of 103 children (206 eyes) were measured using table autorefractor, retinoscope and handheld photo-refractor. In each participant, spherical power, astigmatism power, and astigmatism axis were analyzed by paired t-test to calculate mean difference and 95% LoA. The Bland-Altman plot was performed to assess measurement agreement of the measured refractive error among the devices. The Spearman correlation analysis was performed to investigate the relationship between devices.

Results : In Bland-Altman plot, spherical power and astigmatism power showed high agreement in handheld photo-refractor and retinoscope, and astigmatism axis showed high agreement in table auto-refractor and retinoscope. It was measured towards myopic direction in table autorefractor. In myopic and hyperopic subjects, it was measured towards myopic direction in handheld photo-refractor than retinoscope. In addition, there was a high correlation between handheld photo-refractor and retinoscope in spherical power, astigmatism power and astigmatism axis. The spherical power and the astigmatism power were similar to refractive power of the handheld photo-refractor and the retinoscope. In the astigmatism axis, retinoscope and table autorefractor showed similar to refractive power, but there were some differences according to the measuring devices and there was no statistically significant difference.

Conclusion : For the children who are not cooperative, a handheld photo-refractor can measure refractive errors more rapidly, and can be useful if they are examined in the correct posture.
