SIGNIFICANCE
Our study found a good agreement between three autorefractors. Not only will readers benefit as they can now compare data measured with either device in different studies but the three devices can be used in the same study to generate one pool of data, which can be analyzed together.
PURPOSE
The present study aims to evaluate the agreement of three commonly used autorefractors in children and adolescents, and the potential for their interchangeable application in a large-scale study.
METHODS
Participants from seven schools were enrolled using cluster sampling. Refractive errors were measured using the following three autorefractors under cycloplegic conditions in random sequence: Topcon KR-8900, Nidek ARK-510A, and Huvitz HRK-7000A. Refractive errors were compared in terms of spherical equivalent refraction (SER), cylinder power, and the J0 and J45 by repeated-measures analysis of variance (RM-ANOVA) and Bland-Altman 95% limits of agreement (95% LoA).
RESULTS
A total of 2072 participants aged from 4 to 18 years were included. The mean ± SD and 95% LoA of the differences in SER between Topcon and Nidek, Topcon and Huvitz, and Nidek and Huvitz were 0.01 ± 0.24D (-0.46 to 0.48), -0.06 ± 0.31D (-0.66 to 0.54), and -0.07 ± 0.26D (-0.58 to 0.44), and those for the differences in cylinder power were -0.07 ± 0.26D (-0.57 to 0.44), 0.01 ± 0.32D (-0.63 to 0.64), and 0.07 ± 0.28D (-0.48 to 0.62), respectively (RM-ANOVA, P < .001). Further, the mean differences in J0 and J45 between each refractor pair ranged from -0.03 to 0.01, and the 95% LoA were -0.78 to 0.74, -0.79 to 0.74, and -0.73 to 0.72 for J0 and -0.86 to 0.87, -0.86 to 0.88, and -0.83 to 0.84 for J45, respectively.
CONCLUSIONS
Our study will allow for use of these three autorefractors interchangeably in large screening studies.
意义
我们的研究发现三种自动验光仪之间具有良好的一致性。这不仅使读者受益，因为他们现在可以在不同研究中比较使用任何一种仪器测量的数据，而且这三种仪器可用于同一研究以生成一组数据，从而可以一起进行分析。
目的
本研究旨在评估三种常用自动验光仪在儿童和青少年中的一致性，以及它们在大规模研究中可互换应用的可能性。
方法
采用整群抽样法从七所学校招募参与者。在睫状肌麻痹状态下，随机顺序使用以下三种自动验光仪测量屈光不正：拓普康KR-8900、尼德克ARK-510A和伟伦HRK-7000A。通过重复测量方差分析（RM-ANOVA）和布兰德-奥特曼95%一致性界限（95%LoA）比较球镜等效屈光度（SER）、柱镜度数以及J0和J45方向的屈光不正。
结果
共纳入2072名年龄在4至18岁之间的参与者。拓普康与尼德克、拓普康与伟伦、尼德克与伟伦之间SER差异的均值±标准差及95%LoA分别为0.01±0.24D（-0.46至0.48）、-0.06±0.31D（-0.66至0.54）、-0.07±0.26D（-0.58至0.44），柱镜度数差异的均值±标准差及95%LoA分别为-0.07±0.26D（-0.57至0.44）、0.01±0.32D（-0.63至0.64）、0.07±0.28D（-0.48至0.62）（RM-ANOVA，P<.001）。此外，每对验光仪之间J0和J45的平均差异范围为-0.03至0.01，J0的95%LoA分别为-0.78至0.74、-0.79至0.74、-0.73至0.72，J45的95%LoA分别为-0.86至0.87、-0.86至0.88、-0.83至0.84。
结论
我们的研究将允许在大型筛查研究中互换使用这三种自动验光仪。
