Risk factors
By Mayo Clinic staffSeveral factors can predispose you to developing keratoconus, including:
- Wearing ill-fitting hard contact lenses. If you wear rigid contact lenses and they haven't been fitted properly, the constant pressure or continual injury they cause can lead to keratoconus.
- Certain inherited diseases. The risk of developing keratoconus is higher if you have certain conditions, such as Down syndrome or certain retinal diseases.
- Family history of keratoconus. Most people with keratoconus have no family history of the disease, but researchers have found that in some cases there may be a family connection.
