Supplemental Digital Content: The appendix, available at https://links.lww.com/OPX/A325, lists the 95% reference range for Zernike coefficients (μm) for preschool-age children, school-age children, and adolescents. As not all the data belong to normal distribution, the detailed results are listed in the Appendix for reference. For the data that belonged to normal distribution, (−1.96 s, +1.96 s) were used to calculate the 95% normal reference range, which are shown in bold. For data that did not belong to normal distribution, the ranks were calculated and correspond to the 2.5th and 97.5th percentiles for 95%.
