    Comparison of a New Swept-Source Anterior Segment Optical Coherence Tomography and a Scheimpflug Camera for Measurement of Corneal Curvature

    Purpose: To evaluate the agreement of corneal curvature measured by a newly introduced swept-source anterior segment optical coherence tomography (CASIA2) and Pentacam (Oculus, Wetzlar, Germany). Methods: Corneal curvature was measured in 49 healthy subjects (age: 24.8 ± 4.36) by using CASIA2 and Pentacam . Repeatability was evaluated for CASIA2, and agreement between the CASIA2 and Pentacam was assessed. The coefficient of repeatability, the relative coefficient of repeatability, the range of the limits of agreement were analyzed, and Bland–Altman plots were performed to assess the interdevice agreement of measurement. Results: For the intradevice reliability of the CASIA2, the mean difference ...
