The authors aimed to assess refractive error and axial length in children aged seven to eight years (grades 1-2) starting education in South China. The study reviewed 301 students and obtained data for analysis from 291 (50.2% female). Average axial length was 22.88 ±0.09mm and average spherical equivalent was -0.75 ±0.13D. From age seven to eight years, axial length, astigmatic power and spherical equivalent increased. Axial length correlated highly with refraction but not visual acuity. The authors acknowledge the limitations of this study with small sample size and non-cycloplegic refraction.
