摘要
目的分析三种角膜直径测量方法对角膜水平直径测量的一致性及其在后房型有晶状体眼人工晶状体植入术(IOL)中的应用。设计诊断试验。研究对象行双眼ICL植入的患者23例46眼。方法术前应用量规、IOLMaster及Pentacam眼前节分析系统三种测量方法测量角膜水平直径,比较三种方法测量结果的相关性及一致性。主要指标相关系数、95%的一致性界限(Lo A)。结果量规、Pentacam、IOLMaster测量46眼的角膜水平直径分别为(11.60±0.34)、(11.54±0.32)、(11.94±0.35)mm。量规与Pentacam,量规与IOLMaster,Pentacam与IOLMaster测量结果均高度相关(r=0.895、0.897、0.874,P均=0.000)。量规和Pentacam、量规和IOLMaster、Pentacam与IOLMaster测量结果的95%Lo A分别为(-0.24,0.36)mm,(-0.68,0.01)mm,(-0.70,-0.09)mm。结论量规与Pentacam在有晶状体眼人工晶状体植入术测量角膜水平直径的应用中一致性较好,临床应用中可相互替代。量规与IOLMaster、Pentacam与IOLMaster在临床应用中不可相互替代。
Objective To compare horizontal corneal diameter [white-to-white（WTW） distance] measurements with measuring caliper, IOLMaster, and Pentacam in the patients before ICL implantation. Design Diagnostic test. Participants 23 cases（46 eyes） who underwent ICL implantation. Methods The preoperative horizontal corneal diameter was measured using measuring caliper, IOLMaster,and Pentacam. Analysis of the correlation and agreement were performed. Main Outcome Measures 95% limit of agreement（Lo A）.Results The mean WTW distance measurements were（11.60 ±0.34） mm as obtained with measuring caliper and（11.54 ±0.32） mm with Pentacam and（11.94 ± 0.35） mm with IOLMaster. Measuring caliper versus Pentacam, measuring caliper versus IOLMaster, Pentacam versus IOLMaster were highly correlated（r=0.895,0.874, 0.897, respectively. all P=0.000）. The 95% Lo A for caliper versus Pentacam, caliper versus IOLMaster, Pentacam versus IOLMaster was（-0.24, 0.36） mm,（-0.68, 0.01） mm,（-0.70,-0.09） mm respectively. Conclusion Measuring caliper and Pentacam can be used interchangeably to measure WTW in clinical practice. Measuring caliper and IOLMaster, Pentacam and IOLMaster cannot be considered interchangeable, when it comes to measure WTW.
