Summary

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.

Detailed description

To investigate the relationship between axis length (AL) and refractive error (RE). 894 eyes with low hyperopia to emmetropia (-0.50D ≤ spherical equivalent (SE) ≤ +2.00D), comprising 1007 eyes with moderate to high myopia (-11.00D ≤ SE ≤ -4.00D) were analyzed in this study. Cycloplegic RE 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.
