DSAEK More Successful Under These Circumstances
A successful outcome using Descemet stripping automated endothelial keratoplasty (DSAEK) tends to occur when donors are diabetes-free, and when there are no operative complications, according to a randomized trial involving 1,330 eyes. Additionally, long-term postop outcomes seem to be better in recipients with Fuchs dystrophy vs those with pseudophakic/aphakic corneal edema (PACE).
Participants were a median 70 years of age, and underwent DSAEK for Fuchs corneal dystrophy (94%) or PACE (6%). They were randomized to receive a donor cornea with preservation time of either 0 to 7 days (n=675) or 8 to 4 days (n=655). Investigators looked at graft success at 3 years. Among the results:
- 94% of grafts were still clear and considered successful at 3 years.
- After adjusting for preservation time, eyes whose donors had diabetes were more than twice as likely to experience primary/early failure.
- Patients with PACE were more than 3 times more likely to experience late failure.
