This study aimed to analyze factors affecting stereoacuity outcomes in patients of PRAET treated with PPC and surgery.Study Design: Retrospective study.Methods: Sixty-six patients with alignment within 10 prism diopters at final visit with PPC and surgery were included. According to the final stereoacuity, patients were grouped into the fine group (≤ 60 arcsec (“)), the coarse group (60 “ 6 months, ≤ 2 years; late: > 2 years) was carried out with the Kruskal–Wallis test.Results: There were no differences in ages at initial PPC, at surgery, at final visit, durations of misalignment, of PPC, or after surgery; however, significant differences in ages at onset and initial visit were found. Age at onset in the absent group was significantly earlier than those of the fine and the coarse groups (p 2 years, 18 patients (72%) showed fine or coarse stereoacuity (p 2 years.Keywords: partially refractive accommodative esotropia, prism correction, stereoacuity, critical period, surgery
