摘要: BACKGROUND Remnant interface fluid following Descemet stripping automated endothelial keratoplasty (DSAEK) is associated with postoperative detachments. The aim of this study was to assess outcomes intraoperative optical coherence tomography (iOCT) guided meticulous peripheral corneal sweeping for removal during ultra-thin (UT) DSAEK. METHODS This retrospective included all eyes underwent iOCT UT-DSAEK from October 2016 February 2018 at the Hanusch Hospital, Vienna, Austria. Peripheral performed remove excess fluid. Central graft thickness (CGT) measured prior surgery, after bubbling and sweeping. rates were compared between that rebubbling those did not. RESULTS Overall, 28 patients a mean age 73.9 ± 10.0 years included. An in 89.3% (n = 25) cases. Following 84% (n = 21) performed, remnant no longer identified. height reduced 17.31 ± 15.96 μm 3.46 ± 9.52 μm (p < 0.001) CGT by 7% (p < 0.001). Rebubbling 17.9% (n = 5) group had greater proportion identified end surgery despite (60.0% versus 4.4%, p = 0.01). CONCLUSION subclinical nearly 90% led resolution majority Eyes persistent are more likely require subsequent rebubbling.
