Anterior‐segment swept‐source ocular coherence tomography and scheimpflug imaging agreement for keratometry and pupil measurements in healthy eyes

Purpose: This study examines agreement between the devices Anterion® and Pentacam HR® used for corneal and pupil measurements in healthy eyes. Methods: The parameters compared between the two devices were: anterior Km (D), anterior K2 (D), anterior K1 (D), anterior K1 axis (°), anterior astigmatism (D), anterior K max (D), posterior Km (D), posterior K2 (D), posterior K1 (D), posterior K1 axis (°), posterior astigmatism (D), CCT (μm), thinnest point thickness (μm), thinnest point X‐coordinate (mm), thinnest point Y‐coordinate (mm), pupil diameter (mm), pupil center‐corneal vertex distance (mm) (angle kappa), pupil centroid angle (°), pupil centroid X‐coordinate (mm), and pupil centroid Y‐coordinate (mm). Results: The Student's t test for independent samples identified significant differences (p
