Figure 1 - Microkeratome versus manually dissected donor tissue for Descemet stripping endothelial keratoplasty: A randomized prospective study
Graft asymmetry index was calculated in four semimeridians (0°, 90°, 180° and 270°) using anterior segment optical coherence tomography (AS-OCT): (a) in the axis of 0 and 180 degree, (b) in the axis of 90 and 270 degree
