Variability in Topographic Measurements in Keratoconus
Methods: Seventy two eyes of 38 patients with keratoconus were recruited. Patients were divided into three groups based on mean TA (Group 1: <3D, group 2: ≥3D and <6D and group 3: ≥6D). Two consecutive scans with two minutes intervals were performed by the same operator with Pentacam. Topographic astigmatism (TA) and mean keratometry (Km) readings from anterior and posterior surface, maximum keratometry (Kmax), central corneal thickness (CCT) and Belin/ Ambrósio enhanced ectasia display (B/A) from both scans were recorded. The differences of these parameters in two scans were analyzed.
