DMEK offers faster visual recovery compared to UT-DSAEK, study finds

Posted on

Descemet’s membrane endothelial keratoplasty (DMEK) offers faster visual recovery compared to ultra-thin Descemet’s stripping automated endothelial keratoplasty (UT-DSAEK), while both techniques have similar long-term visual acuity and rejection rates, according to a study.

The review focused on the proportion of patients achieving a best spectacle-corrected visual acuity (BSCVA) of 20/20 at 6 months post-surgery, the rejection rate 1 year after surgery, BSCVA at the last follow-up, and the postoperative immunomodulating regimen.

The results revealed that a higher proportion of DMEK patients achieved a BSCVA of 20/20 at 6 months compared to other techniques. UT-DSAEK and DMEK demonstrated similar rejection rates; however, UT-DSAEK showed a lower risk of re-bubbling (4% compared to 20% for DMEK).
