| Outline of Final Research Achievements |
We developed empirical formulas to calculate the spherical equivalent at 3-8 years old. We measured refractive status using auto-refractometer, axial length and corneal curvature using noncontact optical biometer under cycloplegia with 1% atropine eye drops twice a day for seven days prior to study visit. 756 eyes of 279 children were examined. We made approximation formulas by multiple regression analysis using axial length(x), the mean corneal curvature(y) and spherical equivalent(z). The approximation formulas in 3, 4, 5, 6, 7 and 8 year-old were z=1111.43/x-321.97/y-7.17, z=1120.68/x-285.33/y-11.83, z=1245.87/x-309.57/y-14.20, z=1177.68/x-278.23/y-14.80, z=1206.80/x-362.55/y-4.59 and z=1075.00/x-307.39/y-5.88 in 8 year-old children, respectively.This method may play a supporting role in health check-up program for children. It may be useful to estimate the refractive error of children who cannot be treated with atropine eye drops due to systemic disease.
