To compare keratometry (Ks and Kf), astigmatism (Ast.), and the astigmatism axes (Ax.) of the posterior surface of the cornea; the total, central cornea thickness (CCT); and the thinnest corneal thickness (TCT) measured using two different measurement methods.
Patients qualified for cataract surgery at the Chair and Clinical Department of Ophthalmology, Division of Medical Science in Zabrze, Medical University of Silesia, Katowice, Poland, were included in the study and monitored with the following two devices: OCT-CASIA2 and Dual Scheimpflug Analyzer GalileiG6. Our work was a randomized, prospective study in which compliance with the agreement of measurements between the devices was evaluated using the Bland-Altman method.
A total of 110 patients (62 females and 48 males) were examined. Overall, 100 eyes of patients that qualified for cataract surgery were enrolled in the study. No statistically significant difference was observed for Total-Ks and Total-Kf. A significant difference was observable for the following parameters: total Ks-ax, total Kf-ax, the total power of astigmatism, and in all parameters of the part of the cornea and corneal thickness (CCT and TCT).
The measurements obtained using Casia2 and the Dual Scheimpflug Analyzer GalileiG6 were significantly different and not interchangeable except for total Ks and Kf.
比较角膜后表面的角膜曲率(Ks和Kf)、散光(Ast.)及散光轴(Ax.);使用两种不同测量方法测量的中央角膜总厚度(CCT)和最薄角膜厚度(TCT)。
纳入波兰卡托维兹西里西亚医科大学扎布热医学院眼科教研室符合白内障手术条件的患者,并使用以下两种设备进行监测:OCT-CASIA2和双Scheimpflug分析仪GalileiG6。本研究为一项随机前瞻性研究,采用Bland-Altman方法评估设备间测量结果的一致性。
共检查了1,10例患者(62例女性和48例男性)。总体而言,100例符合白内障手术条件患者的眼睛纳入研究。Total-Ks和Total-Kf未观察到统计学显著差异。以下参数存在显著差异:总Ks轴、总Kf轴、总散光度数以及角膜部分和角膜厚度(CCT和TCT)的所有参数。
除总Ks和Kf外,使用Casia2和双Scheimpflug分析仪GalileiG6获得的测量结果存在显著差异且不可互换。
