ABSTRACT The objective of this study was to analyze the differences in corneal endothelial cell density between emmetropic, myopic and hyperopic subjects. Corneal endothelial cell density (cells/mm2) was analyzed in 30 emmetropic (n=30; 27.3±4.0 years old), 30 myopic (n=30; 26.6±4.1 years old) and 30 hyperopic (n=30; 26.8±4.4 years old) subjects. The mean of three consecutive measurements of corneal endothelial cell density was obtained by means of non-contact specular microscopy (Topcon SP-2000P noncontact specular microscope, Topcon Corp., Tokyo, Japan). Corneal endothelial cell density ranged from 2833 to 3300 cells/mm2 (mean±SD, 3076±123 cells/mm2), from 2825 to 3316 cells/mm2 (mean±SD, 3048±152 cells/mm2), and from 2820 to 3262 cells/mm2 (mean±SD, 3033±115 cells/mm2) in emmetropic, myopic and hyperopic eyes respectively. No significant differences between emmetropic, myopic and hyperopic eyes were found (p=0.404). In sum, there is no difference in corneal endothelial cell density between emmetropic, myopic and hyperopic eyes.
