Prior to the study, the surgeon had already performed 10 DMEKs. The first 15 consecutive patients were included in group 1 (no premarking and air tamponade) and the other 15 consecutive patients were included in group 2 (premarking and SF\n                      <jats:sub>6<\/jats:sub>\n                      tamponade).

However, there was a statistically significant reduction in primary graft failure (40% vs 0%) and need of rebubbling due to complete or partial graft detachment (40% vs 6%) when comparing group 1 versus group 2.
