CORNEAL TOPOGRAPHY

Course overview

CORNEAL TOPOGRAPHY IS AN INTEGRAL DIAGNOSTIC TOOL IN THE ARMAMENTARIUM OF THE CORNEA, CATARACT, AND REFRACTIVE SURGEONS. THIS ACTIVITY HIGHLIGHTS THE EVOLUTION OF CORNEAL TOPOGRAPHIC MAPPING AND THE METHODS OF EVALUATING THE ANTERIOR AND POSTERIOR SURFACES OF THE CORNEA. THE RADIUS OF CURVATURE OF THE CENTRAL PART OF THE ANTERIOR SURFACE OF THE CORNEA IS MEASURED BY THE SIZE OF THE REFLECTION OF AN IMAGE PROJECTED BY THE KERATOMETER. THE DIFFERENCES BETWEEN TOPOGRAPHY AND TOMOGRAPHY, THE INDICATIONS, TECHNIQUES, AND TOPOGRAPHY MACHINES ARE DESCRIBED. THE ROLES OF TOPOGRAPHY IN THE DIAGNOSIS, AS WELL AS THE PROGRESSION OF CORNEAL ECTASIAS AND PRE AND POST-OPERATIVE EVALUATION IN REFRACTIVE PROCEDURES, ARE SUMMARIZED.
