Brief Summary:
This study aims to investigate the influence of postoperative head position on clinical outcomes after DMEK via a wearable sensor.

Condition or disease
Fuchs Endothelial Corneal Dystrophy Pseudophakic Bullous Keratopathy Chemical Burn of Cornea Posterior Polymorphous Corneal Dystrophy

Detailed Description:

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.

  3. Number of Re-Bubblings [ Time Frame: six months after surgery ]
    need of surgical intervention after DMEK in order to attach the graft

  4. Corneal Endothelial Density [ Time Frame: six months after surgery ]
