Anisometropia was found in 10 (14.9%) children

BCVA Best-Corrected Visual Acuity, D Diopters, SD Standard deviation, UCVA Uncorrected Visual Acuity

ANOVA (Kruskal–Wallis) shows a statistically significant difference in VA and all refractive indexes except in Cylinder between the groups with a p < 0.05
