Summary

KC is a degenerative disorder of the cornea. Keratoconus etiopathogenesis remains unclear and may rely on environmental and genetic factors. Usually considered as a rare disease (\<1/2000), but the prevalence is nowadays growing worldwide up to 1/500. In that pathology, cornea progressively gets thinner, and there is a deformation of the corneal surface which can induce high order optical aberrations and visual impairment.

Eye rubbing is certainly the main factor in the progression or development of keratoconus (KC), yet it is only very partially evaluated and quantified in current management. Environmental and clinical factors will be collected and associated with a eye rubbing Questionnaire, specifically pointing out eye rubbing.
