Keratoconus

This study tests whether it is safe and possible to perform corneal cross-linking on both eyes on the same day in people with keratoconus, a condition where the cornea thins and bulges. Fifteen participants will receive riboflavin eye drops and UV-A light treatment in both eyes a…

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 2 trial tests whether GLK-221 eye drops can safely slow the progression of keratoconus, a condition that thins and bulges the cornea. About 100 adults with keratoconus will use the drops twice daily for several months. The main goal is to see if the drops reduce the st…

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 whether combining a laser vision correction (PRK) with corneal cross-linking improves eyesight and corneal shape better than cross-linking alone in people with keratoconus, a condition that thins and bulges the cornea. Fifty adults aged 18-40 with mild to moderat…

This early study tests a tiny, permanent metal mesh (nitinol) implant placed inside the cornea to stabilize the eye and improve vision in people with advanced keratoconus. The trial involves 12 adults who are not candidates for other treatments and are currently recommended for a…

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 tests a laser-guided procedure to treat keratoconus, a condition where the cornea thins and bulges, causing blurry vision. The procedure uses OCT scans to plan a custom laser treatment that smooths the cornea and strengthens it with cross-linking. Researchers aim to se…

This study is testing a new eye imaging device called the VG200D, which uses advanced technology to take detailed pictures of the eye. Researchers want to see if it works as well as a standard device for measuring parts of the eye in people with glaucoma, retina problems, corneal…

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 aims to improve how doctors detect, classify, and treat irregular corneas caused by conditions like keratoconus, dry eye, and corneal scars. Researchers will use a special imaging device called optical coherence tomography (OCT) to get detailed measurements of the corn…

This study screens people with eye diseases to see if they can join other research studies at the National Eye Institute. No treatment is given. Participants undergo eye exams, blood tests, and other procedures to diagnose or evaluate their condition. The goal is simply to determ…

This study tests a special camera that takes super-detailed pictures of the back of the eye (the retina). The goal is to see if this technology can find eye diseases earlier than standard methods. Up to 1,000 people aged 12 and older, with or without eye disease, will have their …

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 study aims to learn more about eye diseases by observing and providing standard care to up to 1,000 people over 5 years. Participants receive regular eye exams, tests, and treatments as needed. The goal is to better understand how eye diseases progress and are inherited, not…

This study follows thousands of people with keratoconus, a condition that makes the cornea thin and bulge. Researchers measure the eye's shape and vision over many years to understand how the disease starts and changes. No new treatments are tested—the goal is simply to learn mor…

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 tests whether artificial intelligence can create simple summaries of eye doctor notes that are easier for patients to understand. About 460 English-speaking adults receiving eye care will get either standard notes or notes plus an AI-generated plain language summary. P…

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 tests a new 4D microscope-integrated OCT system for the first time in people during eye surgery. Researchers want to see if the system is easy to use, safe, and can clearly show eye structures. Five adults having eye surgery will take part. The goal is to improve imagi…

This study looks at how the brain and eye nerves change after corneal crosslinking (CXL), a procedure for keratoconus. Researchers will use brain scans (fMRI) and eye imaging to track pain and nerve healing. The goal is to better understand recovery, not to test a new treatment.

This study gathers standard eye movement and pupil data from 200 healthy volunteers, children, and people with eye or brain conditions using a VR headset called neos™. The headset shows images and tracks where participants look, how their pupils react, and how their eyes move. Th…
