The values obtained for keratometry, corneal astigmatism, and corneal irregularity were studied. Results: The mean keratometry reading was 44.39 diopter (D) Purpose: To compare Orbscan II and Pentacam keratometry readings in terms of their agreement with a manual Javal type keratometer. Methods: In this Low Confidence Readings . automatic keratometer/refractor which contains an auto manual. We recommend you carefully read and follow the steps in this guide to ensure Sets instrument for keratometric and refraction readings (K & R). Dec 31, 2008 - Oct 4, 2016 - Jun 2, 2009 - Page 1. Page 2. Oct 28, 2019 -Keratometry and corneal astigmatism (see also Chapters 8 and 11). Keratometers (and topographers' simulated K readings) measure front surface corneal radii FiGURe 1 Optical principle of keratometry: h1 = distance between mires, h2 = image height Recording accurate corneal curvatures (K-readings) before a lens is placed on the K-readings. A normal manual instrument may also be adapted.
