Testing a light-scanning eye exam to diagnose corneal thinning
Part of Eyes & vision, Genetic & congenital clinical trials.
This study tests whether a special “Brillouin” microscope scan can spot corneal ectasia and related cornea conditions. It may help doctors diagnose problems earlier and better sort out who needs closer eye care.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be able to follow instructions for the eye imaging during the study
- You must be willing to be scanned with the Brillouin microscopy eye test (no “half sessions” for one eye only)
- You are in one of these groups: normal corneas, keratoconus (mild–advanced), or certain recent past/future cornea refractive surgeries (LASIK/PRK)
- If you had LASIK, your eye scans must match normal post-surgery findings—or you must have post-LASIK ectasia for the relevant group
- If you have keratoconus or post-LASIK ectasia, the study uses your cornea measurements (topography and thickness/pachymetry) to confirm
- You cannot have certain eye anatomy issues or related restrictions (like “narrow angles” that block view), and you must not be limited to one eye

This study uses a special, noninvasive microscope technique to study how your cornea tissue behaves. It may help doctors better understand keratoconus and corneal changes after common eye procedures.
This study tests whether a special eye scan called OCT can better identify causes of irregular cornea shape. Results may help doctors sort out different cornea problems so treatment choices, like certain procedures, can be more targeted.
This study uses a special light-based imaging technique called Brillouin microscopy to measure the stiffness and mechanical properties of the cornea (the clear front part of the eye). It aims to understand how different corneal conditions and surgeries affect the cornea's health, which may help improve future treatments.
This study looks at people with corneal disease, especially corneal thinning that can change how the eye focuses light. It may help researchers understand treatments and care plans for these conditions.
This study tests a procedure called Xenia corneal lenticule in people with severe keratoconus or severe post-LASIK corneal thinning who want to avoid a corneal transplant. It aims to improve vision while checking safety and how well the new procedure works over time.
This study uses a special eye scan to look at the top layer of the cornea (the clear front of the eye) to help detect early signs of keratoconus, a condition where the cornea thins and bulges. It could help with early diagnosis and better treatment decisions.
