Excimer versus Femtosecond Laser Assisted Penetrating Keratoplasty in Keratoconus and Fuchs Dystrophy: Intraoperative Pitfalls

Figure 3

Different profiles of FLAK, upper and lower diameter are given in millimeters. Black and red bars indicate mean corneal thickness divided by 3 (meaning that the cornea was divided in anterior 2/3 and posterior 1/3). (a) Top hat profile used in Fuchs dystrophy enables a higher transplantation rate of corneal endothelial cells. (b) Mushroom profile used in keratoconus patients leads to less endothelial cell transplantation.
