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＞ 28 mm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) mm.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 crror 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.
