Official title

Randomized Comparison of Standard vs. Accelerated Corneal Crosslinking for Treatment of Corneal Neovascularization With or Without Concomitant Inflammation and/or Infection

Overview

The study objective is to assess safety and efficacy of photo-activation of riboflavin for treatment of corneal neovascularization with or without concomitant inflammation and/or infection.

Interventions

  • Combination product 30 minute photoactivation of riboflavin 0.1%
    Use of riboflavin 0.1% eye drops and 3mW/cm2 UVA light for 30 minutes
  • Combination product 10 minute photoactivation of riboflavin 0.1%
    Use of riboflavin 0.1% eye drops and 9mW/cm2 UVA light for 10 minutes

Primary outcome measures

  • corneal neovascularization as a proportion of the total corneal area [Time frame: 6 months]

Eligibility criteria

Inclusion criteria

  • 18 years of age or older
  • With active inflammation or infection causing vascularization and possibly melting of the cornea, or vessels extending into the cornea causing lipid deposition, or vascularization that could significantly increase the risk of rejection of a current or planned corneal transplant, or vessels that continue to extend into the cornea despite topical treatment with corticosteroids.
  • Signed written informed consent.

Exclusion criteria

  • Known sensitivity to treatment medications
  • Current condition that in the investigator's opinion could compromise safety or data integrity.
  • Pregnancy (including plan to become pregnant) or lactation during the course of the study

Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.
