Video Analysis
All surgical video recordings were analyzed by 2 graders (M.B.M. and H.J.) using a standardized assessment form. One grader was masked regarding the clinical outcomes of the surgery. The overall skin-to-skin surgical time and duration of surgical steps (eg, descemetorhexis, graft unfolding, etc.) were meticulously recorded. The difficulty of the descemetorhexis was coded in 3 groups based on time (ie, fast: ≤5 minutes, average: >5–≤10 minutes, and slow: >10 minutes). Directly after insertion of the graft into the AC, graft configuration was determined based on geometry and number of folds. As such, 6 distinct shapes were distinguished: double scroll, tight roll, loose roll, taco, unscrolled, and wrinkled (Fig. Coding the various graft shapes directly after insertion in the AC, based on graft geometry and number of folds. The distinctive graft shapes were grouped as either favorable (A, B, C) or unfavorable (D, E, F).
