Title

Converting to topical anesthesia for Descemet’s stripping automated endothelial keratoplasty

Purpose	To evaluate the complications and difficulties converting from paraocular to topical anesthesia in Descements stripping automated endothelial keratoplasty.
Methods	Four eyes in three consecutive patients were retrospectively evaluated (three with DSAEK and one with combined phacoemulsification and DSAEK). Outcome measures were patients`pain score, number of complications and adverse events registered perioperatively and postoperatively.
Results	All procedures were completed without any complications. All patients tolerated the procedure well. No significant differences in endothelial cell were found at final follow up.
Conclusion	Topical anesthesia provided acceptable analgesia during surgery and showed that DSAEK procedure can be performed without akinesia and could be represent an alternative anesthetic modality for patients in whom retrobulbar or peribulbar anesthesia is contraindicated.
