目的:比较IOLMaster与接触式A超测量中央前房深度和眼轴长度的差异,以评价两者在人工晶状体度数计算参数测量中的准确性.方法:2006-10/2007-01在我院眼科施行白内障超声乳化摘除手术联合人工晶状体植入的患者121例(137眼),分别用IOLMaster与接触式A超于术前测量中央前房深度和眼轴长度.结果:IOLMaster与接触式A超测量中央前房深度分别为(2.94±0.49)mm,(2.58±0.51)mm,配对t检验,两者的差值为(0.36±0.30)mm(P＜0.001),差异有显著性,相关系数r=0.823(P＜0.001).测量眼轴长度分别为(24.37±3.04)mm,(23.81±2.83)mm,配对t检验,两者差值为(0.56±0.34)mm(P＜0.001),差异有显著性,相关系数r=0.996(P＜0.001).结论:IOLMaster与接触式A超均可用于前房深度和眼轴长度的测量,两者的相关性好.但基于光学原理的IOLMaster在准确测量眼轴长度和前房深度的同时,简便、快捷、非接触的特点是A超无法比拟的,并可同时测量出其他相关参数.

· AIM: To compare the measurement of anterior chamber depth (ACD) and axial length (AL) by IOLMaster and contact ultrasonic (US) axial scan (A-scan).· METHODS: Measurements of ACD and AL were prospectively obtained in 137 eyes of 121 subjects with the IOLMaster compared with measurements with the US.· RESULTS: There was an excellent correlation between IOLMaster and US measurements for the ACD (r=0.823;P＜0.001) and AL (r=0.996;P＜0.001). The mean values of the parameters measured by IOLMaster and US were,respectively, as follows: ACD, 2.94±0.49mm, 2.58±0.51mm;AL, 24.37±3.04mm, 23.81±2.83mm. The mean differences of ACD and AL values between IOLMaster and US measurements were 0.36 ±0.30mm, 0.56 ±0.34 mm respectively, and they proved to be statistically significant (P＜0.001), With the 95%limits of agreement (LoA) from -0.08mm to +0.38mm for ACD and from -0.09mm to +0.69mm for AL.· CONCLUSION: As noncontact biometry, IOLMaster provides accurate values. A high degree of agreement between US and IOLMaster was noted. It not only has the advantage of performing noncontact examinations, but also produces various additional data simultaneously and may thus obviate the need for multiple examinations. Further studies are needed to assess the interchangeability of measurements in clinical practice.
