Fig. 4From: Comparison of corneal endothelial cell measurements by two non-contact specular microscopesPoor correlation between coefficient of value (CV) of endothelial cell measurements with the Topcon and the Konan microscope: Bland-Altman-analysis. The CV values between the two instruments show a greater than five percent difference (broken lines) in 65 % of measurements (22 of 34), and a greater than ten percent difference in 32 % of measurements (11 of 34)Back to article page
