Eye surgery showdown: which cornea transplant is safer?
NCT ID NCT04417959
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compared two types of cornea transplant surgery (DSAEK and DMEK) for people with Fuchs' endothelial dystrophy, a condition that clouds the cornea. Researchers measured vision and tracked side effects like swelling and eye pressure in 112 participants. The goal was to find out which method offers better vision and fewer complications.
