AI summary

From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.

The trial is looking for people with keratoconus or corneal ectasia (a thinning and bulging of the clear front of the eye). It compares 2 ways of doing corneal crosslinking.

Age
10 Years to 90 Years
Sex
All sexes can join.
Disease stage
A diagnosis of keratoconus or corneal ectasia. The title says the disease is getting worse (progressive).

Main reasons for not taking part

  • Past eye problems in the study eye that could lead to complications, such as herpes infection of the cornea, corneal dystrophy or corneal melt
  • Marked scarring of the cornea in the area to be treated
  • Past chemical injury or slow healing of the eye surface in the study eye
  • Known sensitivity to the study medicine, or significant dry eye or other conditions that may slow healing
  • Being pregnant, planning a pregnancy or breastfeeding during the study

The registry criteria, word for word

Who can take part

  • Diagnosis of keratoconus or corneal ectasia
  • Provision of written informed consent

Who cannot take part

  • Previous ocular condition in the study eye that may predispose for future complications including history of corneal disease (e.g., herpes simplex, herpes zoster keratitis, recurrent erosion syndrome, corneal melt, corneal dystrophy, etc.)
  • Known sensitivity to study medication
  • History of chemical injury or delayed epithelial healing in the study eye
  • A current condition, including clinically significant dry eyes or use of medications know to induce dry eye symptoms, that, in the treating physician's opinion, would interfere with or prolong epithelial healing
  • Clinically significant corneal scarring in the proposed treatment zone
  • Pregnancy (including plan to become pregnant) or lactation during the course of the study

About the trial

What the trial wants to find out

This randomized study compares 2 variations of corneal crosslinking for treatment of keratoconus or corneal ectasia.

The 2 groups in the trial

  • PulsedExisting treatment, for comparison

    Treatment with 0.1% riboflavin eye drops and pulsed 18 milliwatt/cm2 ultraviolet A light for 10 minutes

    Treatment: Riboflavin 0.1% ophthalmic solution and pulsed light

  • Non-pulsedExisting treatment, for comparison

    Treatment with 0.1% riboflavin eye drops non-pulsed 9 milliwatt/cm2 ultraviolet A light for 10 minutes

    Treatment: Riboflavin 0.1% ophthalmic solution and non-pulsed light
