Fig. 8From: Accuracy and safety of partial thickness femtosecond laser radial and arcuate keratotomy incisions in porcine eyesFluorescent images depicting endothelial cell loss for PTIs of increasing residual corneal depth. Red color depicts area of damaged endothelial cells and green represents the fluorescence emitted from healthy cells. a Damaged/dead cells are densely distributed around the through-cut (residual corneal bed thickness 0 μm. b Endothelium exhibiting a lower density of damaged/dead cells as shown by the lesser extent of red fluorescence (residual corneal bed thickness 77 μm) and c No damaged/dead cells (residual corneal bed thickness 92 μm)Back to article page
