Impact of 10% SF Gas Compared to 100% Air Tamponade in Descemet's Membrane Endothelial Keratoplasty.

Purpose: To compare the clinical outcomes following Descemet's membrane endothelial keratoplasty (DMEK) with 100% air tamponade versus 10% sulfur hexafluoride (SF) tamponade.

Methods: Retrospective analysis of 108 consecutive DMEK cases subdivided by anterior chamber tamponade with 54 eyes receiving 10% SF and 54 eyes receiving 100% air injection. A post-hoc matched analysis revealed no statistically significant differences between the groups.
