Abstract
Objectives: To assess the influence of age and gender on ocular biometric values and corneal astigmatism features in individuals undergoing phacoemulsification surgery and intraocular lens implantation.
Methodology: This retrospective study measured ocular biometrics and corneal keratometric astigmatism using the IOLMaster 700 instrument prior to phacoemulsification surgery and intraocular lens implantation.
Results: Analysis included ocular biometric and keratometric values from 3385 eyes of 3385 patients. Lens thickness (p < 0.001, r = 0.387), mean keratometry (p < 0.001, r = 0.156), and corneal astigmatism (p < 0.001, r = 0.082) were positively correlated with age. Conversely, axial length (p < 0.001, r = -0.133), anterior chamber depth (p < 0.001, r = -0.244), and horizontal white-to-white corneal diameter (p < 0.001, r = -0.226) exhibited negative correlations with age. Increasing age led to a significant shift towards against-the-rule astigmatism (p < 0.001, r = 0.248). Mean keratometry was significantly lower in males than females (p < 0.001). Axial length, anterior chamber depth, lens thickness, and white-to-white corneal diameter were higher in males compared to females (all ps ⩽ 0.001). Corneal astigmatism types differed significantly between genders (p < 0.001), with against-the-rule being more prevalent among males (52.9%) and with-the-rule astigmatism having the highest prevalence among females (40.3%).
Conclusions: Mean keratometry and lens thickness increased, while axial length and anterior chamber depth decreased with age. Males exhibited higher values for axial length, anterior chamber depth, and lens thickness, whereas females had steeper corneas.
目的评估年龄和性别对接受超声乳化手术和眼内晶体植入术的患者眼部生物测量值和角膜散光特征的影响:这项回顾性研究使用 IOLMaster 700 仪器在接受超声乳化手术和眼内晶体植入术前测量眼部生物测量值和角膜角膜散光:分析包括3385名患者3385只眼睛的眼部生物测量值和角膜测量值。晶状体厚度(p r = 0.387)、平均角膜度数(p r = 0.156)和角膜散光(p r = 0.082)与年龄呈正相关。相反,轴长(p r = -0.133)、前房深度(p r = -0.244)和角膜水平白对白直径(p r = -0.226)与年龄呈负相关。随着年龄的增长,逆规则散光显著增加(p r = 0.248)。男性的平均角膜度数明显低于女性(p ps ⩽0.001)。角膜散光类型在性别间存在显著差异(P 结论:男性和女性的角膜散光类型不同:随着年龄的增长,平均角膜度数和晶状体厚度增加,而轴向长度和前房深度减少。男性的轴长、前房深度和晶状体厚度值较高,而女性的角膜较陡。
