Abstract

CLINICAL RELEVANCE

Ophthalmic lens adaptation requires accurate measurements of physiognomy parameters and frame angles, with a great impact on subject vision, especially when personalised progressive addition lenses are prescribed.

BACKGROUND

The aim of this study is to describe interdevice agreement between different methods and traditional methods (frame ruler).

METHODS

The agreement of the interpupillary distance, nasopupillary distance and fitting point height measured with four devices (PD-5, OptiCenter, Visioffice and a frame ruler) and of pantoscopic and frame wrap angles measured with three devices (OptiCenter, Visioffice and Essilor standard ruler) was assessed in 21 healthy volunteers, by a Bland-Altman analysis; mean difference and limits of agreement (LoA) were calculated.

RESULTS

Frame ruler nasopupillary distance measurements showed limited agreement with PD-5 [-0.38 ± 1.03 (LoA -2.40 to 1.64) and 0.44 ± 1.02 (LoA -1.72 to 2.61)] and Visioffice [0.62 ± 1.24 (LoA -1.81 to 3.05) and -0.16 ± 1.72 (LoA -3.54 to 3.22)] measurements for the right and left eyes, respectively. Poor agreement was found for interpupillary distances (PD-5 [0.21 ± 1.47 (LoA -2.67 to 3.09)], OptiCenter [-0.05 ± 1.16 (LoA -2.32 to 2.22)] and Visioffice [0.46 ± 1.95 (LoA -3.36 to 4.28)]), fitting point height (OptiCenter [-1.27 ± 2.56 (LoA -6.27 to 3.75) and -0.92 ± 2.77 (LoA -6.35 to 4.51)] and Visioffice [-5.88 ± 6.21 (LoA -18.05 to 6.29) and -5.98 ± 6.12 (LoA -17.98 to 6.02)] for the right and left eyes, respectively) and pantoscopic and frame wrap angles (OptiCenter [-4.13 ± 3.75 (LoA -11.48 to 3.22) and -1.09 ± 0.60 (LoA -2.27 to 0.09)] and Visioffice [-6.18 ± 3.53 (LoA -13.10 to 0.74) and -1.93 ± 3.49 (LoA -8.77 to 4.91)], respectively).

CONCLUSIONS

These results suggest that measurements of physiognomy and frame angles are not interchangeable between assessed devices and that these differences could induce lens centration errors with a large impact on progressive addition lens prescriptions.

摘要

临床相关性

眼科镜片适配需要准确测量相貌参数和镜架角度，这对受试者的视力有很大影响，特别是在定制个性化渐进式附加镜片时。

背景

本研究旨在描述不同方法与传统方法（镜架尺）之间的设备间一致性。

方法

在 21 名健康志愿者中，使用四种设备（PD-5、OptiCenter、Visioffice 和镜架尺）测量瞳孔间距、鼻侧瞳孔距离和配镜点高度，使用三种设备（OptiCenter、Visioffice 和依视路标准尺）测量斜视和镜架包角，通过 Bland-Altman 分析评估其一致性；计算平均差异和一致性界限（LoA）。

结果

镜架尺鼻侧瞳孔距离测量值与 PD-5 相比[右眼-0.38±1.03（LoA -2.40 至 1.64）和 0.44±1.02（LoA -1.72 至 2.61），左眼-0.62±1.24（LoA -1.81 至 3.05）和-0.16±1.72（LoA -3.54 至 3.22）]和 Visioffice [右眼 0.62±1.24（LoA -1.81 至 3.05）和-0.16±1.72（LoA -3.54 至 3.22），左眼 0.44±1.02（LoA -1.72 至 2.61）]测量值的一致性较差。瞳孔间距（PD-5 [0.21±1.47（LoA -2.67 至 3.09）]、OptiCenter [-0.05±1.16（LoA -2.32 至 2.22）]和 Visioffice [0.46±1.95（LoA -3.36 至 4.28）]）、配镜点高度（OptiCenter [-1.27±2.56（LoA -6.27 至 3.75）和-0.92±2.77（LoA -6.35 至 4.51）]和 Visioffice [-5.88±6.21（LoA -18.05 至 6.29）和-5.98±6.12（LoA -17.98 至 6.02）]）和斜视和镜架包角（OptiCenter [-4.13±3.75（LoA -11.48 至 3.22）和-1.09±0.60（LoA -2.27 至 0.09）]和 Visioffice [-6.18±3.53（LoA -13.10 至 0.74）和-1.93±3.49（LoA -8.77 至 4.91）]）的测量值一致性也较差。
