Official Title: COLLAGEN CROSS-LINKING WITH ULTRAVIOLET-A IN ASYMMETRIC CORNEAS
Brief Summary: This study will assess changes in visual acuity and corneal symmetry after corneal collagen cross-linking (CXL) of asymmetric corneas.
Detailed Summary: This study will evaluate the results of Corneal Collagen Crosslinking (CXL) in patients with conditions that include keratoconus, forme fruste keratoconus, post-LASIK ectasia, pellucid marginal degeneration, forme fruste pellucid marginal degeneration, diurnal fluctuation post-radial keratotomy, or Terrien's marginal degeneration. This is an outcomes study, all patients receive treatment.
