Fuchs Endothelial Corneal Dystrophy Pseudophakic Bullous Keratopathy Chemical Burn of Cornea Posterior Polymorphous Corneal Dystrophy |
After Descemet Membrane Endothelial Keratoplasty (DMEK) patients are recommended to keep a strict supine position within the first few days after surgery in order to attach the graft to the corneal stroma. It has not yet been investigated to what extent the head position actually has an effect on the outcome.
In this study, the participants head position will be continuously monitored within the first three days after DMEK. Participants wear a headband in which a small sensor is inserted. The degree of deviation from the neutral position will then be correlated with clinical outcomes.
