Abstract
PURPOSE:To evaluate the impact of venting incision on graft detachment in Descemet stripping automated endothelial keratoplasty (DSAEK).MATERIALS AND METHODS:Retrospective comparative study on DSAEK procedure performed with (n = 13) and without (n = 39) venting incision. Patients were treated with DSAEK for various causes of endothelial decompensation between February 2014 and April 2016. The rate of postoperative graft detachments documented on anterior segment optical coherence tomography was compared in both groups.RESULTS:Paracentral venting incision decreases the rate of graft displacement. Non-venting group (nvg) had 28.2% graft displacement compared to venting group (vg) which had 7.6% graft displacement.CONCLUSION:Venting incision is a simple and safe manoeuvre to facilitate graft adherence in DSAEK, especially in caseswith presence of high-risk factors for graft detachment.
