• Desktop autorefractometer showed excellent agreement with cycloplegic retinoscopy. • Vision Screener V100 demonstrated lower accuracy, especially for astigmatism. • TAR achieved ICC values above 0.95, confirming high cycloplegic reliability. • VS tended to underestimate cylindrical values even under full cycloplegia. • This is the first study evaluating the cycloplegic performance of the V100 device. To evaluate the cycloplegic accuracy of the Vision Screener V100 (VS) and a desktop autorefractometer (TAR) in comparison with cycloplegic retinoscopy (CR) in children, and to compare the findings with current literature. This prospective observational study included 50 pediatric patients (100 eyes) with a mean age of 9.8 ± 1.7 years. Cycloplegic measurements were obtained using the VS, TAR, and CR. Agreement between methods was analyzed using intraclass correlation coefficients (ICC) and Bland–Altman plots. Differences in spherical and cylindrical values were specifically assessed. TAR showed excellent agreement with CR, with ICC values above 0.95 for both spherical and cylindrical measurements. In contrast, the VS demonstrated moderate correlation for spherical values (ICC ≈ 0.82) and lower correlation for cylindrical values (ICC ≈ 0.60). Bland–Altman plots revealed that TAR had narrower limits of agreement with CR, particularly for astigmatism, whereas VS showed wider variability. These findings are consistent with previous reports indicating that non-cycloplegic photoscreening devices such as the VS tend to underestimate hyperopia and show reduced reliability in astigmatism assessment. TAR demonstrates excellent concordance with CR under cycloplegia, whereas the VS shows notably lower accuracy, especially in detecting astigmatism. Our results highlight the importance of cycloplegic evaluation for accurately assessing refractive errors in children.
