Abstract

The aim of this research was to compare corneal thickness measurements obtained by a slit-scanning method with those obtained by noncontact specular microscopy, with a focus on the midperipheral (3.0 mm) region of the cornea. In adults with up to 8.50 diopters of myopia, single measurements of corneal thickness were performed with specular microscopy (Topcon SP-2000P) at central, 3.0 mm nasal, and temporal midperiphery locations. Slit-scanning pachymetry (Orbscan II) measurements were then taken and data extracted for 2.0 mm diameter sample zones at the central, 3.0 mm nasal, and temporal locations.
