All patients underwent assessments of spherical equivalent (SE), axial length (AL), exodeviation, and binocular function relating to accommodation and convergence. Examinations were conducted at baseline and 12-month. SE and AL changes were compared among groups. Univariate and multivariate linear analyses were employed to investigate the association between myopic shift and IXT, as well as other clinical parameters.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Three groups showed comparable ages, genders and SEs at baseline (all <jats:italic>P<\/jats:italic>\u2009&amp;gt;\u2009.05). During 12-month follow-up, the rate of myopic shift varied among groups. Significant differences in SE progression (<jats:italic>P<\/jats:italic>\u2009=\u2009.006) and AL elongation (<jats:italic>P<\/jats:italic>\u2009=\u2009.014) between Group A and Group C were observed.
