Corneal thickness measurements in ovines with ultrasonic pachymetry and noncontact specular microscopy

Abstract

The purpose of this study was to evaluate the central corneal thickness values in normal ovine with Topcon SP-2000P noncontact specular microscope and ultrasonic pachymeter. Central corneal thickness was detemined in 22 eyes of 11 ovines, first with a noncontact specular microscopy (Topcon SP-2000P), then using an ultrasonic pachgmeter (Nidek UP-1000). The central corneal measurements were 654mm e 665mm with Topcon and ultrasonic pachymeter, respectively. The instruments were reliable in their measurements.
