What Causes Keratoconus?
While some experts think patients are born with a certain predilection to keratoconus (and we actually have a genetic test that we offer at our practice to see if you have any of the keratoconus genetic factors), most agree that the only significant risk factor is rubbing of the eyes. Multiple episodes of eye rubbing exerted onto the cornea, can cause corneal deformation and thinning of the cornea, which then can lead to keratoconus. If you only take one thing away from this information—please avoid rubbing your eyes!
