Lens thickness ( p\u2009&lt;\u20090.001, r\u2009=\u20090.387), mean keratometry ( p\u2009&lt;\u20090.001, r\u2009=\u20090.156), and corneal astigmatism ( p\u2009&lt;\u20090.001, r\u2009=\u20090.082) were positively correlated with age. Conversely, axial length ( p\u2009&lt;\u20090.001, r\u2009=\u2009\u22120.133), anterior chamber depth ( p\u2009&lt;\u20090.001, r\u2009=\u2009\u22120.244), and horizontal white-to-white corneal diameter ( p\u2009&lt;\u20090.001, r\u2009=\u2009\u22120.226) exhibited negative correlations with age. Increasing age led to a significant shift towards against-the-rule astigmatism ( p\u2009&lt;\u20090.001, r\u2009=\u20090.248). Mean keratometry was significantly lower in males than females ( p\u2009&lt;\u20090.001). Axial length, anterior chamber depth, lens thickness, and white-to-white corneal diameter were higher in males compared to females (all ps\u2009\u2a7d\u20090.001). Corneal astigmatism types differed significantly between genders ( p\u2009&lt;\u20090.001), with against-the-rule being more prevalent among males (52.9%) and with-the-rule astigmatism having the highest prevalence among females (40.3%).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>Mean keratometry and lens thickness increased, while axial length and anterior chamber depth decreased with age.
