目的:通过IOLMaster和A超对白内障患者不同眼轴及前房深度的测量的比较,探讨两者之间的差异性和相关性。方法:收集本院2010-03/08眼科白内障患者分别进行IOLMaster与A超术前检查,取两项检查均有结果者进行研究。所有患者术前经同一位医师进行测量。首先进行无创IOLMaster标准测量,测量眼轴长度及前房深度,取平均值;然后对比采用10Hz A超测量,取平均值,得到前房深度及眼轴长。结果:眼轴长度A超和IOLMaster在眼轴<22mm时差异有统计学意义(P=0.001)。在眼轴>26mm和22～26mm时,P=0.808,P=0.405,没有统计学意义;眼轴长度A超和IOLMaster相关系数分别为r=0.998,r=0.991,r=0.783,在眼轴>26mm和22～26mm时高度相关。而<22mm时中度相关。前房深度A超和IOLMaster相关系数分别为r=0.851,r=0.628,r=0.673,均为中度相关。结论:本实验发现眼轴IOLMaster略长于A超,<22mm组有显著性差异,在眼轴>26mm和22～26mm之间组没有显著性差异。但三组之间均具有较好的相关性。前房深度IOLMaster与A超三组均未见差异性,且具有一定相关性。研究还发现眼轴IOLMaster略长于A超时,可见到前房深度有时IOLMaster略长于A超,有时A超略长于IOLMaster。

AIM:To explore the difference and correlation between different axial length and Anterior Chamber Depth(ACD) by means of IOLMaster and A ultrasound in the clinical cataract patients.METHODS:Cataract patients were collected for 8 months and examined respectively preoperatively by IOLMaster and A ultrasound.The results of both examinations were checked.Every patients were examined by the same skilled doctor.The axial length and ACD were examined by IOLMaster in first step,and then by A ultrasound in second step.RESULTS:There was some significant difference in the axial length <22mm,and no difference in the axial length >26mm and between 22mm and 26mm.A ultrasound and IOLMaster axial length relationship were 0.998,0.991 and 0.783.The correlationship about their ACD were 0.851,0.628,0.673.CONCLUSION:It was found that the IOLMaster’s axial length was longer than A ultrasound.There have good relationship among three groups about their axial length and A ultrasound,though there are some difference.
