Comparison of IOL master 700 and Lenstar for measurement of axial lengths

    摘要
  • 摘要:
      目的  比较IOL master 700和Lenstar测量眼轴(AL)的差异性、相关性和一致性。
      方法  采用横断面研究纳入2018年5—7月于中国医科大学附属第四医院、中国医科大学眼科医院就诊的患者94例(94眼), 每位患者先后行Lenstar、IOL master 700测量AL。观察2种测量方法的差异性、相关性和一致性。
      结果  Lenstar及IOL master 700在AL的检测中无显著差异性(P>0.05), 但具有高度相关性和良好一致性。
      结论  IOL master 700、Lenstar的眼轴测量结果有良好一致性和高度相关性，可以相互替代。

     

    Abstract:
      Objective  To compare the differences, correlation, and consistency of results in measurement of axial lengths(AL) by Lenstar and IOL master 700.
      Methods  In this cross-sectional study, a total of 94 patients(94 eyes) between May and July 2018 from Fourth Affiliated Hospital of China Medical University and Ophthalmology Hospital of China Medical University were selected as research objects, and each patient performed Lenstar, IOL master 700 in sequence to measure the AL. The difference, correlation, and consistency of the two instruments were compared. They are random analysis of variance, Pearson correlative analysis, and Bland-Altman analysis respectively.
      Results  Lenstar and IOL master 700 had no statistically significance in the differences in AL measurement(P>0.05), but has a higher correlation and good consistency.
      Conclusion  The two methods have higher correlation and consistency in the AL measurements, and can be interchangeable.
