Abstract：
OBJECTIVE: To develop a new schematic scheme for efficiently recording the key parameters of gas permeable contact lens (GP) fits based on current consensus.
METHODS: Over 100 established GP fitters and educators met to discuss the parameters proposed in educational material for evaluating GP fit and concluded on the key parameters that should be recorded. The accuracy and variability of evaluating the fluorescein pattern of GP fit was determined by having 35 experienced contact lens practitioners from across the world, grading 5 images of a range of fits and the topographer simulation of the same fits, in random, order using the proposed scheme. The accuracy of the grading was compared to objective image analysis of the fluorescein intensity of the same images.
RESULTS: The key information to record to adequately describe the fit of an GP was agreed as: the manufacturer, brand and lens parameters; settling time; comfort on a 5 point scale; centration; movement on blink on a ±2 scale; and the Primary Fluorescein Pattern in the central, mid-peripheral and edge regions of the lens averaged along the horizontal and vertical lens axes, on a ±2 scale. On average 50-60% of practitioners selected the median grade when subjectively rating fluorescein intensity and this was correlated to objective quantification (r=0.602, p<0.001). Objective grading suggesting horizontal median fluorescein intensity was generally symmetrical, as was the vertical meridian, but this was not the case for subjective grading. Simulated fluorescein patterns were subjectively and objectively graded as being less intense than real photographs (p<0.01).
CONCLUSIONS: GP fit recording can be standardised and simplified to enhance GP practice.

摘要：
目的：根据当前的共识，开发一种新的示意图方案，用于有效记录透气性隐形眼镜（GP）拟合的关键参数。
方法：100多名已建立的GP钳工和教育者开会讨论了教材中提出的用于评估GP拟合的参数，并就应记录的关键参数进行了总结。通过来自世界各地的35名经验丰富的隐形眼镜从业者来确定评估GP配合的荧光素模式的准确性和可变性，对一系列拟合的5张图像进行分级，并对相同的拟合进行地形图模拟，随机，使用所提出的方案订购。将分级的准确性与相同图像的荧光素强度的客观图像分析进行比较。
结果：记录以充分描述GP的适合性的关键信息被同意为：制造商，品牌和镜片参数；稳定时间；5点刻度上的舒适度；定心；±2刻度上的闪烁运动；以及中央的主荧光素图案，沿水平和垂直透镜轴平均的透镜的中间外围和边缘区域，在±2标度上。当主观评定荧光素强度时,平均50-60%的从业者选择中值等级,并且这与客观定量相关(r=0.602,p<0.001)。客观分级表明水平中值荧光素强度通常是对称的，垂直子午线也是如此，但主观评分并非如此。模拟荧光素图案被主观和客观地分级为不如真实照片强烈(p<0.01)。
结论：GP适合记录可以标准化和简化，以增强GP实践。
