Goodman Eye Center
To evaluate the safety and effectiveness of the PXL Platinum 330 system for performing corneal cross-linking (CXL) for the treatment of ectatic disorders.
Patients with progressive keratoconus, pellucid marginal degeneration, or at risk for post-refractive corneal ectasia will be recruited and undergo epithelial-on corneal crosslinking with the Peschke PXL-330 system using pulsed, accelerated energy delivery. Patients will undergo monitoring for 1 year, with serial measurements of corneal topography, visual acuity, intraocular pressure, pachymetry, and visual function questionnaire.
Inclusion Criteria: Subjects who have one or both eyes that meet criteria 1 and 1 or more of the following criteria will be considered candidates for this study: 1.10 years of age or older 2. Presence of central or inferior steepening 3. Axial topography consistent with keratoconus, post-surgical ectasia, or pellucid marginal degeneration 4. Presence of one or more findings associated with keratoconus or pellucid marginal degeneration, such as: 1. Fleischer ring 2. Vogt's striae 3. Decentered corneal apex 4. Munson's sign 5. Apical Corneal scarring consistent with Bowman's breaks 6. Scissor…
Riboflavin will be used to load the cornea, followed by UV-A crosslinking of the cornea
