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 pupil measurements in healthy eyes. Methods: The parameters compared two were: anterior Km (D), K2 K1 axis (°), astigmatism K max posterior CCT (μm), thinnest point thickness X-coordinate (mm), Y-coordinate diameter center-corneal vertex distance (mm) (angle kappa), centroid angle (mm). Results: Student's t test independent samples identified significant differences (p < 0.05) flat axis, K, steep mean K. For these last three measurements, although significant, none of were clinically relevant. Corneal power except Kf showed excellent Anterion Pentacam. Pupil differed significantly both groups 0.05). Conclusions: In a clinical setting we would not recommend interchangeable use measurement parameters.
