摘　　要：对138例（138眼）白内障患者分别应用IOLMaster系统和直接接触式A超进行眼轴测量，比较两者的测量结果。A超和IOLMaster系统测量的眼轴结果高度相关，但IOLMaster系统测量的眼轴长度略长于A超结果，且差异有统计学意义（P〈0．01）。A超与IOLMaster系统两者差值的平均值为（-0．198±0．146）mm，随着眼轴增加，两种测量方法之间的差值亦有所增加。对于眼轴〉28133131的白内障患者，IOLMaster系统对于眼轴测量的误差控制范围要低于A超。IOLMaster系统是一较为简单、快速、可靠的非接触眼轴测量方法。To compare the measurements of axial length by A-scan ultrasound and IOLMaster. For a total of 138 eyes, axial length was measured with IOLMaster followed by contact A-scan ultrasound. Though a great correlation existed between two measurements, the axial length was a little longer with IOLMaster than with A-scan ultrasound. And the difference was statistically significant （P 〈 0. 01 ）. The mean difference of two methods was （ -0. 198± 0. 146） ram. With the elongation of axial length, the difference of two methods also increased. For cataract patients with axial length 〉 28 mm, the control range of error from IOLMaster for axial length was much lower than that from A-scan. Thus IOLMaster is a simple, fast, reliable and non-contact measurement method of axial length.
