Study Summary

This trial is testing a new system to treat corneal thinning conditions to see if it is safe and effective.

Who is the study for?
This trial is for people aged 12 or older with certain corneal thinning conditions like keratoconus, who haven't improved after two weeks of standard treatment for bacterial/fungal keratitis. Candidates must have specific signs of corneal disease and be willing to follow the study schedule. Pregnant individuals, those planning pregnancy, lactating, or with a history of certain eye diseases are excluded.Check my eligibility
What is being tested?
The trial tests the safety and effectiveness of the PXL-330 Platinum device paired with Peschke riboflavin solution in treating corneal thinning disorders. It aims to see if this combination can strengthen the cornea by cross-linking its collagen fibers.See study design
What are the potential side effects?
Potential side effects may include discomfort during treatment, temporary visual disturbances, inflammation or infection risk post-treatment. Long-term risks could involve changes in vision that might require corrective lenses.
