Keratoconus Clinical Trial
Official title:
Validation Study on Eye Rubbing Questionnaire in Patients With or Suspected of Having a Keratoconus (KC)
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.
CNRK center is working on an eye rubbing questionnaire since 2017 in order to quantify that pejorative factor. Patient education can limit in a certain amount the Keratoconus progression. Thus, our objective will be to evaluate the therapeutic impact on Keratoconus progression of patient's education against eye rubbing according to an eye rubbing Questionnaire. The validation of a dedicated questionnaire is an important act that will allow the scientific evaluation of this factor with both environmental and behavioral traits. It can thus be integrated into our care activity for its intrinsic educational and therapeutic virtues and for its decision-making aid for certain treatments. It will be useful first of all for the refinement of the correct prescription of corneal collagen crosslinking for evolving KC or KC with a high risk of progression. ;
