Comparison of axial length measurement on swept-source optical biometry and optical coherence interferometry
Journal Title: Eye Science (Yanke Xuebao) - Year 2020, Vol 35, Issue 2
Abstract
[Objective:] To compare the detection rates and consistency of axial length (AL) measured by a new swept-source optical coherence tomography biometry (OA-2000) and an optical coherence interferometer (IOLMaster 500) in cataract patients, and to evaluate the application value of OA-2000 in the axial length measurement of cataract patients. [Methods:] In this retrospective study, 561 cataract patients (954 eyes) admitted to Guangzhou Aier Eye Hospital from March to August in 2018 were recruited. AL measurement before cataract surgery was performed by OA-2000 and IOLMaster 500 respectively. The detection rates, correlation and the consistency were analyzed based on chi-square test, Pearson correlation coefficient, intraclass correlation coefficient (ICC) and Bland-Altman plot, respectively. [Results:] The success rates of AL measurement by OA-2000 and IOLMaster 500 was 95.4% and 64.7%, respectively. The detection rate with two instruments significantly differed (P<0.05). Pearson correlation analysis showed a high correlation of AL measurement values between OA-2000 and IOLMaster 500 (r=1, P<0.05), and the scatter plots of AL measurement values were distributed in a straight line. Bland-Altman analysis revealed a high consistency in the AL measurement values between two instruments. [Conclusion:] The consistency and correlation AL measurement are high between OA-2000 and IOLMaster 500. In the AL measurement of cataract patients, the detection rate of OA-2000 is higher than that of IOLMaster 500, which deserves higher application value in clinical practice.
