Descemet stripping automated endothelial keratoplasty (DSAEK) has several advantages over penetrating keratoplasty.[1, 2] Surgical outcome, however, depends upon factors like atraumatic graft insertion and reducing dislocations. During our learning curve, we tried to overcome certain problems associated with various surgical steps by developing modifications in the standard technique.
DSAEK was performed in four eyes of four patients with pseudophakic corneal oedema (n = 3) and Fuchs’ endothelial dystrophy (n = 1).
An 8.0 mm donor lenticule was prepared using a microkeratome (Moria, Antony, France) using a 350 μm head.
The anterior corneal surface was marked using a 9 mm marker (Moria). A peritomy was fashioned in the superior quadrant, …
