Corneal ectasia

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 phase 3 trial tests whether a shorter 18-minute ultraviolet (UVA) light exposure works as well as the standard 24-minute exposure during corneal crosslinking for keratoconus and similar conditions. The treatment uses riboflavin (vitamin B2) eye drops followed by UVA light to…

This Phase 3 trial tests a treatment called corneal crosslinking (CXL) for people with Down syndrome who have keratoconus, a condition where the cornea thins and bulges, blurring vision. The procedure uses vitamin B2 eye drops and ultraviolet light to strengthen the cornea. Resea…

This study tests a new device called the Gebauer Lenticule, a tiny implant made from pig collagen, for people with severe keratoconus or post-LASIK ectasia. The implant is placed inside the cornea to strengthen it and improve stability, potentially delaying or avoiding the need f…

This study tests a device that uses riboflavin (vitamin B2) drops and UV light to stiffen the cornea, the clear front part of the eye. It is for people with keratoconus or similar conditions that cause the cornea to bulge and blur vision. The goal is to see if the treatment safel…

This study is testing a new imaging technique called Brillouin microscopy to see if it can diagnose keratoconus and other corneal thinning conditions. Researchers will scan the corneas of 168 volunteers, including healthy people and those with keratoconus or post-LASIK ectasia, t…

This study is developing imaging and computer simulation tools to predict how a person's cornea (the clear front part of the eye) will change after treatments like crosslinking for keratoconus or LASIK for vision correction. Researchers will take detailed images of the eyes of 60…

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 is testing whether a special eye scanner (OCT) can help fit scleral contact lenses more accurately than the usual method. Researchers will enroll 258 people with conditions like keratoconus or scarred corneas. Each participant will have lenses fitted both the standard …
