Accelerated Corneal Collagen Crosslinking Protocols
Keratoconus
About this trial
This is an interventional treatment trial for Keratoconus
Eligibility Criteria
Inclusion Criteria: Patients with mild to moderate progressive keratoconus with maximum keratometry value Kmax < 56.0 D, Corneal thinnest pachymetry ≥ 400 µm and Corrected distance visual acuity (CDVA) equal to or better than 20/200 Snellen's acuity. Established keratoconus progression: Increase of 1.0D or more in the manifest cylinder Increase of 0.5D or more in the manifest refraction spherical equivalent Increase of 1.0D or more in Kmax Increase of 0.75D or more in Kmean decrease of 2% or more in central thickness Age: 18-40 y Clear cornea Exclusion Criteria: Corneal scarring Previous corneal surgery Severe keratoconus wit non measurable refraction or Kmax ≥ 56 D or Corneal thinnest pachymetry < 400 µm
