PENG Xianyao,SUN Ruizhu,LYU Fan.. The influence of operators for the repeatability and reproducibility of axial length measured by Lenstar[J]. JOURNAL OF WEZHOU MEDICAL UNIVERSITY, 2016, 46(9): 649-651,655.
Abstract：Objective: To explore the influence of different operators to the repeatability and reproducibility of Lenstar in axial length measurements. Methods: Sixty left eyes of 60 participants were enrolled. Each participant was performed two measurements which was finished by operator I and operator II, each measurement including at least three continue measure. The SD (standar deviation) and CV (coefficient of variation) of all the participants was calculated to evaluate the reproducibility of operator I and operator II. The difference between operator I and operator II in AL measurement and it’s 95%CI (confidence interval) was calculated to evaluate the reproducibility between operator I and operator II. Results: The Mean±SD of operator I and operator II were (24.05±0.02) mm and (24.05±0.02) mm. The CV of operator I and operator II were 0.07% and 0.06%. The Mean±SD of the difference of AL between operator I and operator II was (0.00±0.03) mm. The 95%CI of the difference of AL between operator I and operator II was 0.00±0.06. Conclusion: The factor of operators don’t affect the repeatability and reproducibility of Lenstar.
