NCT07217249
This multi-center clinical trial is designed to assess the association of diabetes in a cornea donor with transplant success and loss of endothelial cells 5 years following Descemet membrane endothelial keratoplasty (DMEK). Study eyes are assigned to receive either a cornea from a donor without diabetes or a cornea from a donor with diabetes in a masked fashion.
NCT07024693
The purpose of this study is to evaluate the pharmacodynamics, safety, and tolerability of DT-168 Ophthalmic Solution in pre-keratoplasty patients with Fuchs endothelial corneal dystrophy.
NCT04440280
This protocol will investigate whether topical application of N-acetyl cysteine (NAC) eye drops decreases oxidative stress and confers cytoprotection in patients with FECD.
NCT05376176
This is a Phase IIa study to assess efficacy and safety of STN1010904 ophthalmic suspension (0.03%, and 0.1 %), twice daily dosing when compared to Placebo in subjects diagnosed with Fuchs Endothelial Corneal Dystrophy (FECD). This study will consist of a Screening Period of up to 15 days and an 18-month Double-Masked Treatment Period, including 9 individual visits to the study site.
NCT05795699
A study to assess the safety and efficacy of K-321 in participants with FECD after descemetorhexis.
NCT06966167
The goal of this observational study is to compare the mid- to long-term efficacy of femtosecond laser-assisted cataract surgery (FLACS) and conventional phacoemulsification surgery (CPS) in patients with moderate to severe Fuchs' endothelial corneal dystrophy (FECD) complicated by cataracts. The main questions it aims to answer are: Does FLACS lead to better preservation of corneal endothelial cells compared to CPS in patients with moderate to severe FECD? How do visual outcomes and corneal transparency compare between FLACS and CPS in this patient population? Comparison Group: Researchers will compare patients undergoing FLACS with those undergoing CPS to evaluate differences in endothelial cell loss, corneal thickness, visual acuity, and corneal transparency. Participants: Adults aged 40 years and older diagnosed with moderate to severe FECD (endothelial cell density \<1500 cells/mm²). Patients scheduled for cataract surgery at participating centers. Participants will undergo: Preoperative evaluations, including visual acuity tests, corneal endothelial cell density assessment (central and five peripheral zones), corneal thickness, and corneal densitometry. Surgical intervention with either FLACS or CPS. Postoperative follow-ups at 1 day, 3 days, 1 week, 1 month, 3 months, 6 months, 1 year, and 2 years, including assessments of endothelial cell density, visual acuity, and corneal thickness. This study aims to provide evidence-based recommendations for optimizing surgical strategies in high-risk patients with FECD and cataracts.
NCT06969586
The goal of this study is to learn if topical ROCK inhibitors protect endothelial corneal cells in patients with glaucoma and Fuchs endothelial corneal dystrophy after cataract surgery. The main question it aims to answer is: do topical ROCK inhibitors decrease the loss of corneal endothelial cells after cataract surgery? Researchers will compare topical ROCK inhibitor to a placebo (a look-alike substance that contains no drug) Participants will: Take topical ROCK inhibitor or a placebo every day for 4 weeks after cataract surgery and visit the clinic for checkups and tests.
NCT06425666
The purpose of the study is to investigate whether there is a difference in BCVA in patients who receive one of the following two surgeries: intervention group (arm 1) cataract surgery alone and control group (arm 2) cataract surgery combined with removal of the diseased endothelial cells and the attached Descemet's membrane followed by transplantation of a healthy endothelial cell layer with attached Descemet's membrane ("triple-DMEK" group; comparator therapy). The secondary objectives are to compare the two surgical methods with regard to other visual functions and optical as well as morphological differences, to safety, to quality of life, and to safety.
NCT04387331
This study aims to investigate the influence of postoperative head position on clinical outcomes after DMEK via a wearable sensor.
