Illustrations of the tested VisuMax Circle patterns (Carl Zeiss Meditec, Jena, Germany) and the incision parameters selected for respective pattern. Pattern A creates a side cut within the cap cut (CC; in blue). Pattern B creates a lamellar ring posterior to the cap cut. Pattern C creates a lamellar ring anterior to the cap cut. Pattern D creates a lamellar ring adjacent to the cap cut. The parametric settings of the patterns tested in the current study can be found in Table 1. OD = outer diameter; JD = junction diameter; SD = side cut depth; SA = side cut angle; HA = hinge angle; JU = junction upper depth; JL = junction lower depth
