Abstract

Objectives: 1. Evaluate changes in ocular axial length and corneal refraction in myopic eyes in children after 1 year of follow-up. 2. Learn some factors affecting changes in eyeball axial length and corneal refraction in myopic eyes in children. Research subjects and methods: Descriptive study: first examination and after 1 year of 65 children diagnosed with myopia aged 6-15 years old without physical eye damage. We measured ocular axial length and corneal radius of curvature using the IOL Master machine. Results: The average Spherical Equivalent (SE) gradually increased after 1 year: -0.57± 0.47D. Average eyeball Axial Length (AL) gradually increased after 1 year: 0.31±0.23mm. There is little change in Corneal Power(CP). Myopia degree and axial length tended to increase across all ages (6–15 years), with a faster rate of increase in younger children. Boys had longer axial lengths than girls. The relationship between corneal refractive power and age remained stable. Girls exhibited higher corneal refractive power than boys. Axial length and myopia showed a strong inverse relationship throughout the follow-up period. Corneal refractive power was inversely related to myopia but not statistically significant
