To investigate the relationship between axis length (AL) and refractive error. eyes of low hyperopia to emmetropia subjects, comprising eyes with moderate to high myopia (-11.00D ≤ SE ≤ -4.00D) were analyzed in this cross-sectional study. Cycloplegic refractive error was measured with the autorefractor, AL was measured with the IOL master. Association between AL and refractive error were evaluated by linear regression analysis. The mean of AL and its correlation with SE, sex, and age were evaluated.
