摘要/Abstract

摘要： 目的比较使用矢高仿真软件与标准试戴片验配角膜塑形镜结果的一致性。设计诊断试验。研究对象 北京同仁医院验配角膜塑形镜、平均年龄（9.9±2.2）岁的青少年近视患者60例（117眼）。方法所有患者均使用标准试戴片进行角膜塑形镜验配，由视光师根据患者的角膜地形图数据及经验选择第一片试戴片的定位弧（AC）曲率值，然后根据试戴后的裂隙灯荧光染色和角膜地形图结果调整，确定需要生产镜片的AC曲率值。采用北京市眼科研究所研发的矢高仿真软件（TR-SAG），根据输入的患者角膜平坦K值、e值、角膜直径自动计算出角膜的矢高，进一步在镜片数据库中寻找与角膜矢高最相近的镜片，以镜片的AC曲率值作为矢高仿真软件的输出结果。使用单因素方差分析、Bland-Altman 散点图评价两种方法的差异性，使用组内相关系数评价两种方法结果的一致性。主要指标 镜片的AC曲率值。结果视光师确定的第一片试戴片AC曲率值为（42.15±1.30）D，试戴、调整后确定的需生产镜片的AC曲率值为（42.10±1.28）D；TR-SAG计算的镜片AC曲率值为（42.12±1.28）D，三者比较差异无统计学意义（F=0.050，P=0.951）。TR-SAG计算的镜片AC曲率值与视光师根据经验确定的第一片试戴片AC曲率值的相关系数为0.970（P=0.000），与通过试戴、调整后确定的需生产镜片AC曲率值的相关系数为0.968（P=0.000），均具有很好的一致性。结论 TR-SAG软件计算出的角膜塑形镜生产参数与视光师依经验使用标准试戴片获得的生产参数具有很好的一致性。（眼科，2021，30： 118-123）

Abstract: Objective To compare the consistency of the results of fitting orthokeratology lens based on sagittal height simulation software and standard trial lens. Design Diagnostic tests. Participants 60 subjects (117 eyes, age 9.9±2.2 years) with myopic who needed orthokeratology fitting in Beijing Tongren Hospital. Methods Standard trial lenses were used for orthokeratology fitting in all subjects. The optometrist first experientially selected the first trial lens based on the patient's topographic map data, and then determined the parameters of lens to be produced according to the slit lamp fluorescent staining and the change of the topographic map after the try-on. The AC values of the first trial lens and the lens to be produced were recorded separately. The TR-SAG Sagittal height simulation software was developed by Beijing Institute of Ophthalmology. The software automatically calculates the corneal sagittal height based on the input patient corneal flat K value, e value, and corneal diameter, and further searches for the lens closest to the corneal sagittal height in the lens database. The AC value of the lens was taken as the output of the simulation software. One-way analysis of variance and Bland-Altman scatter plot was used to evaluate the difference between the two methods, and the intra-group correlation coefficient was used to evaluate the consistency of the results of the two methods. Main Outcome Measures AC value of the lens. Results The AC value of the first trial lens determined by the optometrist was 42.15±1.30 D. The AC value of the lens to be produced determined after the try-on was 42.10±1.28 D. And the AC value of the lens calculated by simulation software was 42.12±1.28 D. There was no significant difference among the three groups (F=0.050, P=0.951). The correlation coefficient between the AC value of the lens calculated by simulation software and the AC value of the first trial lens was 0.970 (P=0.000), and the correlation coefficient with the AC value of the lens needs to be produced was 0.968 (P=0.000), which were in good consistency. Conclusions The parameters of the orthokeratology lens calculated by the TR-SAG software are in good agreement with the parameters obtained by the optometrist using the standard trial lens.
