Investigative Study of the Relationship between Central Corneal Thickness and Axial Errors of Refraction

Abstract

ABSTRACT Aim of work: This study aimed to determine the correlation between central corneal thickness and axial refractive errors (axial myopia and axial hyperopia). Methods: Eighty-four eyes were included in this study. They were classified into three groups (Group 1; which included 28 axially myopic eyes, Group 2; which included 28 axially hyperopic eyes and group 3; which included 28 emmetropic eyes). CCT was obtained by pentacam, axial length was obtained by A-Scan ultrasonography and refraction was obtained with auto-refractometer after cycloplegia and being confirmed with trial lenses. Results: The study showed that the mean CCT in the myopia group (group 1) was 531 nm, mean CCT in the hyperopia group (group 2) was 523.5 nm and mean CCT for the emmetropia group (group 3) was 555 nm. CCT was obtained by pentacam, AL was obtained by ultrasound A-scan and refraction was obtained by auto-refractometer after cycloplegia and being confirmed with trial lenses.
