Correlation Between Refraction and Biometric Parameters

Correlation Analysis of Refraction and Biometric Parameters in Chinese Schoolchildren

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

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).

Inclusion Criteria:

• Schoolchildren aged from 6 to 15 years

Exclusion Criteria:

• with previous histories of cataracts, keratitis, strabismus, or other visual impairments
• with history of previous eye surgery
• with unreliable auto-refraction values
• unwilling to participate
