概括

在植入式结合镜头 (ICL) V4c手术后的测量在Pentacam,CASIA II AS-OCT和UBM之间有所不同. 虽然相关,但这些方法在评估ICL金库时是不可互换的.

科学领域:

眼科医生眼科眼科
生物医学光学生物医学光学
医疗成像医学成像

背景情况:

精确测量,眼内透镜和自然透镜之间的空间,对于预测和监测V4c植入植入式眼镜 (ICL) 植入后的结果至关重要.
不同的成像模式可能会产生不同的密室测量,影响临床决策.

研究的目的:

为了比较通过Scheimpflug断层扫描 (Pentacam),前段光学连贯断层扫描 (AS-OCT,CASIA II) 和ICL V4c植入后超声生物显微镜 (UBM) 获得的金库测量.
评估这三种测量技术之间的一致性和相关性.

主要方法:

一项追溯性研究,涉及210名接受ICL V4c植入的患者的210只眼睛.
通过使用Pentacam,CASIA II AS-OCT和UBM获得了金库测量.
统计分析包括重复测量ANOVA,皮尔森相关性,类内相关系数 (ICC) 和布兰德-阿尔特曼图.

主要成果:

平均值为452.64±204.20微米 (Pentacam),538.57±203.54微米 (CASIA II) 和560.95±227.54微米 (UBM),其中有显著差异 (P<0.05).
在所有三种仪器中都发现了强烈的正相关性和良好的整体一致性 (P<0.001).
当值≤250微米时,测量一致性显著下降,特别是在Pentacam和其他两个设备之间.

结论:

五角镜测量结果往往低于CASIA II和UBM,其中UBM产生的值最高.
虽然不能互换,但由于良好的相关性和一致性,这些工具可以作为相互参考.
潘塔卡姆和CASIA II显示出最高的一致性,但在较低的值 (≤250微米) 时,这种情况下降.

Uncertainty in Measurement: Reading Instruments

Counting is the type of measurement that is free from uncertainty, provided the number of objects being counted does not change during the process. Such measurements result in exact numbers. By counting the eggs in a carton, for instance, one can determine exactly how many eggs are there in the carton. Similarly, the numbers of defined quantities are also exact. For example, 1 foot is exactly 12 inches, 1 inch is exactly 2.54 centimeters, and 1 gram is exactly 0.001 kilograms. Quantities...
