Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • topography characteristic of keratoconus (skewed asymmetric bow-tie, inferior steep spot, etc.) and at least one clinical sign e.g., slit lamp findings of Munson's sign, Vogt's striae, Fleischer's ring, apical thinning, Rizutti's sign, etc.

Exclusion criteria
