An unintentional full thickness trephination occurred in the upper-nasal quadrant at the beginning of the surgery. After suturing the perforated area, manual DALK was performed, and an air bubble was left in the anterior chamber. Evaluated outcomes included best spectacle corrected visual acuity (BSCVA), residual recipient bed thickness, endothelial cell count (ECC), graft clarity, rejection, and presence\/absence of double anterior chamber.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      The surgery was completed without any further complications. No double anterior chamber or Urrets\u2013Zavalia syndrome was observed on the first postoperative day. Mean residual recipient bed thickness was 72\u2009\u03bcm and regular.
