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.

Current Primary Outcome: Corrected Distance Visual Acuity (CDVA) [ Time Frame: 6 months ]

Change in corrected distance visual acuity (CDVA) compared to baseline


Original Primary Outcome: Same as current

Current Secondary Outcome:

  • Uncorrected distance visual acuity (UCVA) [ Time Frame: 6 months ]

    Change in uncorrected distance visual acuity (UCVA) compared to baseline

    Secondary: Change at 6 months as compared to baseline in:

    1. Uncorrected distance visual acuity
    2. KMax
  • KMax [ Time Frame: 6 months ]
    Change in Kmax compared to baseline


Original Secondary Outcome: Same as current
