Bullous keratopathy

This Phase 1 trial tests a new cell injection therapy called SNEC-I for people with mild to moderate corneal endothelial dysfunction or bullous keratopathy. The treatment uses non-cultured human corneal endothelial cells injected directly into the eye to restore the inner layer o…

This study compares two types of corneal transplants—PKP and DSAEK—in 334 adults aged 50+ with advanced bullous pseudophakic keratopathy, a condition where the cornea swells and blurs vision. Participants are randomly assigned to one procedure and followed for 2 years to see whic…

This study tests a single injection of AURN001 in 120 adults with corneal swelling caused by endothelial dysfunction. The goal is to see if it improves vision and reduces corneal thickness compared to a placebo. Participants must already have an artificial lens in the eye and be …

This study tests whether giving a laser treatment (transscleral cyclophotocoagulation) to lower eye pressure before a Boston keratoprosthesis (a plastic cornea implant) can prevent or slow glaucoma. Twenty adults who need the implant will receive one of two laser types 4-8 weeks …

This study compares two types of cornea transplant surgery—DSAEK and DMEK—in 220 adults with corneal swelling or Fuchs' dystrophy. The goal is to see which procedure leads to better vision and patient satisfaction one year after surgery. Participants will be randomly assigned to …

This early-stage trial tests a new implant called PVEK for people with corneal swelling from Fuchs' dystrophy or pseudophakic bullous keratopathy. The implant uses a collagen scaffold with human corneal cells to replace damaged tissue. About 15 participants will receive the impla…

This early-stage trial tests the safety of injecting special human cells (EO2002) into the eye to treat corneal swelling. Twelve adults with corneal edema from Fuchs' dystrophy or after cataract surgery will receive multiple injections, with or without Ripasudil eye drops. The ma…

This study tests a new, gentler steroid eye drop plan after corneal transplant surgery. The goal is to prevent rejection while reducing side effects like high eye pressure. About 342 adults getting a DMEK transplant will be followed for two years to see if a milder steroid works …

This early-stage trial tests a new type of corneal graft made from lab-grown human cells. It is for people with mild to moderate corneal damage from conditions like Fuchs' dystrophy or after eye surgery. The goal is to see if the graft is safe and can improve vision. 30 participa…

This study will compare how well patients see after three types of corneal transplants: DSAEK, UT-DSAEK, and DMEK. Researchers will follow 1,000 people who had surgery for Fuchs' endothelial corneal dystrophy or pseudophakic bullous keratopathy. They will measure vision, cell cou…

This long-term study collects data from over 100 eye clinics in Germany to see how corneal transplant surgeries have changed since 2001. Researchers track the number of surgeries, the types of procedures used, and the reasons people need them. The goal is to understand trends, no…

This study gathers eye scan images from 180 people with healthy eyes or eye diseases like glaucoma and retinal disease. The goal is to collect data using a new optical coherence tomography (OCT) device called A10900. No treatment or medication is given. The information will help …

This study uses a special eye scan called OCT to measure swelling in the cornea of people with Fuchs' dystrophy or a related condition. Researchers want to see if this scan can predict how vision changes after surgery. About 60 participants will be observed over time.
