ABSTRACT Objective: To evaluate the corneal endothelial count in patients with keratoconus (KCN) by specular microscopy and correlate with the stage of keratoconus. Methods: Ninety-three eyes from 61 patients with KCN were included in this cross-sectional study. The eyes were classified into KCN stages 1 to 4 according to the Amsler-Krumeich classification using keratometry obtained by corneal topography and pachymetry readings obtained by specular microscopy. Results: Age ranged from 12 to 43 years, mean ± (standard deviation) 22.1 ± 6.7 […]
