: The objective was to assess ocular biometric measurements in relation to age and gender among patients scheduled for cataract surgery, utilizing an optical biometry device. : The optical biometric parameters evaluated included axial length (AL), central corneal thickness (CCT), anterior chamber depth (AD), lens thickness (LT), horizontal corneal diameter (WTW), and keratometry values in the flat (K1) and steep (K2) meridians. Astigmatism (AST) was also measured as the difference between these keratometry values. : A total of 14,183 optical biometric measurements were included in the study. The average age of the participants was determined to be 56 (3-110) years. The average AL was 23.57 ± 1.45 mm, the average AD was 2.76 ± 0.42 mm, the average CCT was 518.13 ± 37.81 μm, the average WTW distance was 11.88 ± 0.59 mm, and the average LT was 4.19 ± 0.51 mm. The keratometry measurements were recorded as K1 = 43.39 ± 1.96 diopters (D), K2 = 44.51 ± 2.31 D, and AST = 1.12 ± 1.15 D. The average values for male eyes in terms of the AL, AD, WTW, and LT measurements were significantly higher than those for female eyes ( = 0.001). The average K1 and K2 values were flatter in males than in females, while the AST value was found to be higher in females ( = 0.001). As age progressed, the mean AL decreased, the CCT decreased, the AD narrowed, the WTW distance decreased, the LT increased, and the keratometric values K1, K2, and AST decreased until the age of 60, after which they increased again. : Research indicates that the measurements of the bulbus oculi are generally larger in males than in females. Furthermore, each of the optical biometric measurements is interrelated. Over time, these measurements may change.
目的是利用光学生物测量设备评估计划进行白内障手术的患者的眼部生物测量数据与年龄和性别的关系。所评估的光学生物测量参数包括眼轴长度（AL）、中央角膜厚度（CCT）、前房深度（AD）、晶状体厚度（LT）、水平角膜直径（WTW）以及平轴（K1）和陡轴（K2）子午线的角膜曲率值。散光（AST）也作为这些角膜曲率值之间的差值进行测量。该研究共纳入了14183次光学生物测量。参与者的平均年龄为56（3 - 110）岁。平均眼轴长度为23.57±1.45毫米，平均前房深度为2.76±0.42毫米，平均中央角膜厚度为518.13±37.81微米，平均水平角膜直径距离为11.88±0.59毫米，平均晶状体厚度为4.19±0.51毫米。角膜曲率测量记录为K1 = 43.39±1.96屈光度（D），K2 = 44.51±2.31 D，AST = 1.12±1.15 D。男性眼睛在眼轴长度、前房深度、水平角膜直径和晶状体厚度测量方面的平均值显著高于女性眼睛（P = 0.001）。男性的平均K1和K2值比女性更平坦，而女性的散光值更高（P = 0.001）。随着年龄增长，平均眼轴长度减小，中央角膜厚度减小，前房深度变窄，水平角膜直径距离减小，晶状体厚度增加，角膜曲率值K1、K2和散光直到60岁时下降，之后又上升。研究表明，男性眼球的测量值通常比女性大。此外，每项光学生物测量都是相互关联的。随着时间推移，这些测量值可能会发生变化。
