Visual acuity (VA) and autorefraction without cycloplegia were assessed in all participants, and some received axial length (AL) measurements. Anisometropia was categorised based on spherical equivalent (SE), cylindrical (CYL), and AL. The prevalence of anisometropia and refractive correction across different ages and sexes, and correlations between ocular parameters, were analysed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The study included 29\u2009153 children aged 6\u201312 (mean age 9.52 \u00b1\u20091.73\u2009years) for VA and autorefraction measurements, and 1176 children for AL measurements. The prevalence of myopia (SE\u2009\u2264\u2009\u22120.50\u2009D), hyperopia (SE\u2009\u2265\u2009+0.50\u2009D), and anisometropia (interocular SE difference \u22651.00\u2009D) was 65.26%, 15.09%, and 16.50%, respectively.
