Descemet Membrane Endothelial Keratoplasty for Fuchs' Dystrophy
(DEKS Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial examines how a cornea donor's diabetes status affects the success of Descemet membrane endothelial keratoplasty (DMEK), a surgery for treating Fuchs' dystrophy, where the inner cornea layer deteriorates. Participants will receive a cornea from either a donor with diabetes or one without, and researchers will compare the results. Ideal candidates include those who participated in a previous related study and are willing to return for follow-ups. As an unphased study, this trial allows participants to contribute to important research that could enhance surgical outcomes for future patients.
Will I have to stop taking my current medications?
The trial information does not specify whether you need to stop taking your current medications.
What prior data suggests that Descemet membrane endothelial keratoplasty is safe?
Research has shown that Descemet membrane endothelial keratoplasty (DMEK) is a safe treatment for corneal issues. Studies have found that DMEK is effective, and patients typically recover smoothly. Most people experience improved vision after the surgery.
Evidence also suggests that serious side effects are rare. In some studies, patients' best-corrected vision ranged from 20/21 to 20/31 over several months of follow-up, indicating that most patients enjoy good vision results without major problems.
In this trial, the cornea may come from donors with or without diabetes. However, past research confirms that the main treatment, DMEK, has a strong safety record.12345Why are researchers excited about this trial?
Descemet membrane endothelial keratoplasty (DMEK) is unique because it involves transplanting only the innermost layer of the cornea, which can lead to faster recovery and better visual outcomes compared to traditional corneal transplant methods like penetrating keratoplasty. Researchers are excited about this approach because it uses corneas from both diabetic and non-diabetic donors to see if donor health impacts the success of the surgery. This could pave the way for more flexible donor criteria and potentially increase the availability of suitable corneas for patients with Fuchs' Dystrophy.
What evidence suggests that this trial's treatments could be effective for Fuchs' Dystrophy?
Research has shown that Descemet membrane endothelial keratoplasty (DMEK) effectively treats Fuchs' Dystrophy, a condition affecting the cornea, the clear front part of the eye. Studies have found that DMEK can significantly improve vision, with about 90% of patients experiencing better sight after the procedure. Compared to other treatments, DMEK yields superior results, with many patients achieving vision of 20/40 or better. The procedure is also considered safe, making it a common treatment for this eye condition. In this trial, participants will receive a cornea from either a donor with diabetes or a donor without diabetes, allowing for a comparison of outcomes based on donor characteristics.678910

What Are the Treatments Tested in This Trial?
Interventions
- Descemet membrane endothelial keratoplasty
Trial Overview
The trial tests if donor diabetes affects the success of a cornea transplant called Descemet membrane endothelial keratoplasty (DMEK) after 5 years. Patients receive a cornea from either a non-diabetic or diabetic donor randomly.
