High-frequency ultrasound, using a 10 MHz sound probe and an immersion technique, enables the measurement of the axial length of the eye to within an accuracy of 0.1 mm. The total axial length of the anterior surface of the cornea to the vitreoretinal interface is measured by ultrasound. Many authors add a retinal thickness factor to the echographic data. Addition of this retinal factor lowers the accuracy of axial length measurements. Biometry of both eyes can detect unilateral high-grade myopia as the only reason for unilateral exophthalmos. Accurate measurements of anterior chamber depth, lens thickness and axial length are of great diagnostic importance in glaucoma and are useful in the therapeutic management of this condition. Accurate biometry and preoperative calculation of intraocular lens power are indispensable procedures in obtaining optimal post-operative results in patients subjected to intraocular lens implantation.
使用10兆赫的超声探头和浸入技术的高频超声，能够将眼轴长度测量至0.1毫米的精度范围内。通过超声测量从角膜前表面到玻璃体视网膜界面的总眼轴长度。许多作者在超声数据中加入视网膜厚度因素。加入这个视网膜因素会降低眼轴长度测量的准确性。双眼生物测量可以检测出单侧高度近视是单侧眼球突出的唯一原因。前房深度、晶状体厚度和眼轴长度的准确测量在青光眼诊断中具有重要意义，并且对这种疾病的治疗管理也很有用。在接受人工晶状体植入的患者中，准确的生物测量和人工晶状体屈光力的术前计算是获得最佳术后效果必不可少的步骤。
