[Purpose] We compared the refractive errors measured by Spot™ Vision Screener (SVS) at a health checkup for 3-year-old children with those measured by a table-mounted auto ref-keratometer (KR-8100) used in a medical institution. [Subjects and Methods] Based on the SVS result from a health checkup for 3-year-old children, 55 children were advised to receive an ophthalmology consultation at Fujieda Municipal General Hospital and were included as subjects. Among them, 94 eyes of 47 subjects could be measured by the KR-8100 at the first medical examination. Their refractive errors measured by the KR-8100 were compared to the refractive errors measured by the SVS at the health checkup. [Results] The average spherical powers were +1.49±1.67 D by the SVS and +0.44±2.66 D by the KR-8100. The spherical powers by the SVS were significantly more hyperopic than those by the KR-8100 (p<0.01). The average cylindrical powers were -1.72±1.19 D by the SVS and -1.27±1.27 D by the KR-8100. The cylindrical powers by the SVS were significantly higher than those by the KR-8100 (p<0.01). Both spherical and cylindrical powers by the SVS showed strong correlations with those by the KR-8100 (rs=0.81 for spherical, rs=0.71 for cylindrical). [Conclusion] In the 3-year-old children who were advised to receive an ophthalmology consultation after a health checkup, their spherical powers measured by the SVS were significantly more hyperopic and the cylindrical powers were significantly higher than those by the KR-8100.
