Abstract Details


To evaluate the prognostic value of intraoperative Optical Coherence Tomography (iOCT) with regard to postoperative graft adherence in endothelial keratoplasty.


University Eye Clinic Maastricht, Maastricht, The Netherlands.


Intraoperative OCT (RESCAN 700, Carl Zeiss Meditec, Germany) was performed at the end of 23 consecutive endothelial keratoplasties (ultrathin Descemet Stripping Automated Keratoplasty (UT-DSAEK), n=14; Descemet Membrane Endothelial Keratoplasty (DMEK), n=9). Scans were reviewed for graft adherence and compared with OCT scans (Casia SS-1000; Tomey, Japan) performed 1 hour, 1 day, 1 week and 1 month postoperatively.


Ten UT-DSAEK and seven DMEK grafts were approximated on iOCT to the host cornea of which nine UT-DSAEK (90%) and five DMEK grafts (71%) remained adherent postoperatively. One UT-DSAEK (10%) and two DMEK grafts (29%) detached significantly postoperatively despite adherence on iOCT. Five UT-DSAEK (36%) and two DMEK (29%) grafts showed some degree of incomplete graft approximation on iOCT, all of which were non-adherent postoperatively.


Complete graft adherence at the end of surgery on iOCT is an effective predictor for graft attachment postoperatively to a greater degree for UT-DSAEK than for DMEK. Partial non-adherence visualized on iOCT is a good predictor for graft detachment post-operatively.
