Participants are eligible to be included in the study if all of the following criteria apply:
•Patients must be 18 years and older at the time of the signing of the informed consent. There is no upper age limit.
•Scheduled for DSAEK or DMEK
•Ability to cooperate fairly well during the examinations
•Willing to participate in the study and capable of giving informed consent, which includes compliance with the requirements and restrictions in the informed consent form (ICF) and in this protocol.
Are the trial subjects under 18? no
Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range 20
F.1.3 Elderly (>=65 years) yes
F.1.3.1 Number of subjects for this age range 110
Participants are excluded from the study if any of the following criteria apply:
•Contraindications for use of any medication (e.g. allergy, pregnancy, breastfeeding)
oPregnancy or possible pregnancy during the study period is considered an exclusion criterion and pregnancy and contraception are commented in more detail in section 8.5
•Preoperative macular edema and/or ongoing treatment for macular edema
•Re-transplantation
•In-operated glaucoma shunt / valve (e.g. Ahmed glaucoma valve)
•Aphakic eyes
•Loss of central vision (expected visual acuity potential after surgery below 0.1 Snellen)
For patients scheduled for corneal endothelial keratoplasty in both eyes, only the first operated eye will be included, however, both eyes will be examined.
