摘　　要：背景眼轴长度和前房深度是人工晶状体（IOL）度数计算公式中的重要参数。目的对IOLMaster、Axis-ⅡA型超声、ODM1000A型眼科超声测量仪测量的眼轴长度及前房深度进行比较。方法同一操作者分别使用IOLMaster、Axis—UA型超声和ODM1000A型眼科超声测量仪测量48例83眼的眼轴长度及前房深度。结果Axis-ⅡA型超声、ODM1000A型眼科超声测量仪、IOLMaster测得眼轴长度的均值分别为（25．79±0．85）、（25．72±0．82）、（26．00±0．83）Film。Axis-ⅡA型超声比ODM1000A型眼科超声测量仪测得眼轴长度长（0．07±0．35）mm，差异无统计学意义（t=1．711，P=0．091）；IOLMaster比ODM1000A型眼科超声测量仪测得眼轴长度长（0．27±0．29）mm，差异有统计学意义（t=-8．570，P：0．000）；IOLMaster比Axis-ⅡA型超声测得眼轴长度长（0．21±0．32）mm，差异有统计学意义（t=-5．931，P=0．000）。3种检查仪测量眼轴长度结果相互呈正相关（r=0．916、0．938、0．928，P〈0．01）。Axis-ⅡA型超声、ODM1000A型眼科超声测量仪、IOLMaster测得前房深度分别为（3．81±0．21）、（3．84±0．25）、（3．83±0．18）mm。Axis-ⅡA型超声比ODM1000A型眼科超声测量仪测得前房深度值小（0．03±0．17）Film，差异无统计学意义（t=-1．324，P=0．189），IOLMaster比ODM1000A型眼科超声测量仪测得前房深度值小（0．01±0．15）mnl，差异无统计学意义（t=0．815，P=0．417），Axis-ⅡA型超声比IOLMaster测得前房深度值小（0．01±0．12）mm，差异无统计学意义（t=-0．900，P=0．371）。3种检查仪测量的前房深度值相互间均呈高度正相关（r=0．735、0．813、0．823，P〈0．01）。结论ODM1000A型眼科超声测量仪可以准确测量眼轴长度及前房深度，但不能替代10LMaster．Background Axial length and anterior chamber depth are important parameters for the calculation of diopter of intraocular lens （IOL）. Objective This study was to investigate and compare the measuring outcomes of axial length and anterior chamber depth with IOLMaster, Axis-U A-scan and ODM 1000A sonograph. Methods This a observational study. Axial length and anterior chamber depth were measured in 83 eyes of 48 patients with IOLMaster,Axis-Ⅱ A-scan and ODM 1000A sonograph by the same operator. The measuring results were compared among the three methods. Results The axial length were （ 25.79 ± 0.85 ） ram, （ 25.72 ± 0.82） mm and（26.00±0.83 ）mm respectively with Axis-Ⅱ, ODM 1000A sonograph and IOLMaster. The difference between Axis-Ⅱ and DM 1000A sonograph was （0.07± 0.35 ）mm without statistical difference between them （t=1.711,P=0.091）. The difference of axial length between IOLMaster and DM 1000A sonograph was（0.27± 0.29 ）rnm with a statistical difference between them（ t =-8. 570 ,P = 0. 000）. The difference between IOLMaster and Axis--Ⅱ was （0.21±0.32 ） mm and showed a statistical difference （ t = - 5.931 , P 〈 0. 01 ）. The positive correlations were found in the axial length values by the each other comparison among the three instruments （r = 0. 916,0. 938, 0. 928, P〈0.01 ）. The anterior chamber depth values were （ 3.81 ±0.21 ） mm, （ 3.84±0.25 ） mm and （ 3.83 ±0. 18 ）mm respectively with Axis-Ⅱ ,ODM 1000A sonograph and 1OLMaster. The difference of anterior chamber depth between Axis-Ⅱ and DM 1000A was （0.03 ±0. 17 ）mm without statistical difference between them （t =- 1. 324, P = 0. 189 ）. The difference in the anterior chamber depth between IOLMaster and DM 1000A was （0.01 ±0. 15 ）mm and that between IOLMaster and Axis-Ⅱ was （0. 01 ±0. 12 ）mm without any statistical differences among them （ t = 0. 815, P = 0.417 ; t = -0. 900, P = 0.371 ）. The high correlation between anterior chamber depth measurements were
