BACKGROUND
To compare the refractive results of hand-held and table-mounted autorefractors.
METHODS
We designed this study as an observational, cross-sectional study. We compared the mean spheric and cylinder power, spherical equivalent, Jackson cross-cylinder values, determined the limits of agreement (LoA), and evaluated the reliability of two autorefractors.
RESULTS
We evaluated 256 eyes of 256 pediatric patients (mean age, 9.12 ± 2.26 years; range, 5-16 years). 49% of the patients were female, and 51% were male. The Nidek HandyRef-K autorefractor measured relatively more astigmatism (P < 0.001) and less hyperopia (P = 0.024). The mean differences and 95% LoA were 0.06 D ± 0.47 D (- 0.82 D to 0.98 D) in spherical power, 0.08 D ± 0.28 D (- 0.47 D to 0.64 D) in cylindrical power, 0.11 D ± 0.47 D (- 0.81 D to 1.01 D) in spherical equivalent, 0.02 D ± 0.36 D (- 0.73 D to 0.69 D) in Jackson cross-cylinder power at 0°, 0.005 D ± 0.54 D (- 1.07 D to 1.06 D) in Jackson cross-cylinder power at 45° We found the difference within 0.50 D in 244 (95%) eyes for spherical power, in 245 (96%) eyes for cylindrical power, 228 (89%) eyes for spherical equivalent, 224 (87%) eyes for Jackson cross-cylinder power at 0°, 213 (83%) eyes for Jackson cross-cylinder power at 45° When comparing devices, there were strong correlations for spherical power (Spearman's rho = 0.99, P < 0.001), cylindrical power (Spearman's rho = 0.88, P < 0.001), and spherical equivalent (Spearman's rho = 0.98, P < 0.001).
CONCLUSION
Two autorefractors showed clinically applicable agreement limits; excellent reliability for spherical power and spherical equivalent and good reliability for cylindrical power; high positive percent agreement for spherical and cylindrical power, spherical equivalent, Jackson cross-cylinder power at 0°and 45°. These results showed that both devices might be used interchangeably for screening of refractive error in children.
背景
比较手持式和台式自动验光仪的屈光结果。
方法
我们将这项研究设计为一项观察性、横断面研究。我们比较了平均球镜和柱镜力、等效球镜、Jackson 交叉圆柱镜值，确定了（差异的）一致性界限（LoA），并评估了两种自动验光仪的可靠性。
结果
我们评估了 256 例儿科患者（平均年龄 9.12±2.26 岁；范围为 5-16 岁）的 256 只眼。49%的患者为女性，51%为男性。尼德克 HandyRef-K 自动验光仪测量的散光（P<0.001）相对较多，远视（P=0.024）较少。球镜力的平均差异和 95%LoA 为 0.06 D±0.47 D（-0.82 D 至 0.98 D），柱镜力为 0.08 D±0.28 D（-0.47 D 至 0.64 D），等效球镜为 0.11 D±0.47 D（-0.81 D 至 1.01 D），Jackson 交叉圆柱镜力在 0°时为 0.02 D±0.36 D（-0.73 D 至 0.69 D），Jackson 交叉圆柱镜力在 45°时为 0.005 D±0.54 D（-1.07 D 至 1.06 D）。我们发现，在 244 只（95%）眼的球镜力、245 只（96%）眼的柱镜力、228 只（89%）眼的等效球镜力、224 只（87%）眼的 0°Jackson 交叉圆柱镜力、213 只（83%）眼的 45°Jackson 交叉圆柱镜力中，差异在 0.50 D 以内。当比较设备时，球镜力（Spearman's rho=0.99，P<0.001）、柱镜力（Spearman's rho=0.88，P<0.001）和等效球镜力（Spearman's rho=0.98，P<0.001）具有很强的相关性。
结论
两种自动验光仪的一致性界限具有临床应用价值；球镜力和等效球镜的可靠性极佳，柱镜力的可靠性良好；球镜和柱镜力、等效球镜、0°和 45°Jackson 交叉圆柱镜力的高度正百分比一致。这些结果表明，这两种设备可能可以互换用于儿童屈光不正的筛查。
