Causes
By Mayo Clinic staffWhat triggers corneal thinning in keratoconus usually is unknown. Some experts believe that keratoconus may not be a single disorder but instead could stem from several different causes. If you have a habit of vigorously rubbing your eyes, it's possible to injure your corneas. A few people who frequently and vigorously rub their eyes develop keratoconus, though a cause-and-effect relationship remains unproved.
