Crosslinking Agent
Corneal Collagen Cross-Linking for Keratoconus
Phase 1
Recruiting
Led By BALAMURALI AMBATI, MD, PhD
Research Sponsored by Pacific Clear Vision Institute
Eligibility Criteria Checklist
Specific guidelines that determine who can or cannot participate in a clinical trial Must have
Axial topography consistent with keratoconus, post-surgical ectasia, or pellucid marginal degeneration
Predicted Post LASIK/PRK stromal ablation depth <350 microns or expected keratometry >47.2 D, or patients undergoing PRK/SMILE in keratoconus suspect eyes
Must not have
History of or active corneal disease (e.g., herpes simplex, herpes zoster keratitis, recurrent erosion syndrome, acanthomeoeba, etc.)
Patients with nystagmus or any other condition that would prevent a steady gaze during the CXL treatment or other diagnostic tests.
Timeline
Screening 3 weeks
Treatment Varies
Follow Up 12 months

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.
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.
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.

Eligibility Criteria:
This trial includes the following eligibility criteria:- You have a known sensitivity or allergy to the medications used in the study.My eye condition is related to keratoconus, surgery complications, or pellucid marginal degeneration.You have a condition called Fleischer ring.My eye shows a bulging sign when looking down.My eye can focus on a close object when covered.I have a history of or currently have a corneal disease.Your cornea is not centered properly.I am having eye surgery and my eye measurements meet specific criteria.I have removed my contact lenses as instructed before the eye test.The topography shows a crab-claw shape.My doctor thinks my condition could slow down my skin healing.My eye infection hasn't improved after 2 weeks of treatment or my cornea is quickly getting thinner.I have streaks in the eye's clear covering.I have significant scarring on my cornea that is not due to keratoconus and may affect treatment.My AvaGen test shows I'm at high risk for keratoconus.I meet the specific eye condition criteria for this study.I don't have conditions like nystagmus that make it hard to keep my gaze steady.My eyes have conditions that could risk future complications.I am 12 years old or older.I have signs of keratoconus or pellucid marginal degeneration.You can keep wearing your scleral lenses during the study, unless your eyes show signs of low oxygen levels, like new blood vessels forming on your cornea.
