Brief summary

To document the refractive status of Chinese schoolchildren and evaluate the association between the degree of refraction and biometric parameters.

Detailed description

In this study, we will analyze the refractive status of schoolchildren and compare the ocular biometrics, including spherical equivalent refraction (SER), pupil distance (PD), corneal curvature (CC), high order aberration (HOA), and central corneal thickness (CCT) between boys and girls. Additionally, we investigate the correlation between the SER in diopters and the other biometric parameters, including PD, CC, HOA, CCT, and body mass index (BMI).
