OPTIMISE — safer steroid plans after DMEK cornea transplant

Official title: Optimized Immunosuppression for Corneal Transplantation: A Multi-center Randomized Controlled Clinical Trial

Run by Maastricht University Medical Center · NCT05716945 · Data updated 2026-11-12

This study tests whether using a milder steroid eye drop plan or stopping steroids earlier after DMEK can still prevent graft rejection while reducing the risk of high eye pressure in adults receiving corneal transplants.

Is this trial a fit for you?

Likely a good fit

Adults aged 21 or older who are registered on the NOTR as candidates for DMEK and who can complete follow-up without contraindications to the study medications are the intended participants.

Probably not a fit

Patients with prior corneal grafts in the study eye, history of uveitis or herpes simplex, HLA-typed allografts, current pregnancy or lactation, or those on other systemic or local immunosuppressants are unlikely to qualify or benefit from the tested regimen changes.

What this trial studies

OPTIMISE is a phase 4 interventional trial enrolling adults listed for DMEK in the Netherlands to compare different postoperative steroid strategies (dexamethasone 0.1%, fluorometholone 0.1%, or stopping steroids). Participants will follow an assigned steroid regimen after their endothelial keratoplasty and attend scheduled follow-up visits to monitor graft health and intraocular pressure. The primary goal is to find an evidence-based, cost-effective regimen that prevents rejection but lowers steroid-induced side effects. Outcomes include rates of rejection, changes in intraocular pressure, and treatment-related complications.

Why it matters

Potential benefit: If successful, patients could have fewer steroid-related side effects such as raised intraocular pressure while maintaining low graft rejection rates.

How similar studies have gone: DMEK itself is well established with low rejection rates, but randomized evidence on milder or shorter steroid regimens after DMEK is limited, so this approach is not yet widely proven.
