Common symptoms include the following:

  • Blurry vision or difficulty seeing objects that are far away
  • Eyeglass prescriptions that need to be changed or adjusted often
  • Eye pain

Seek care immediately if:

  • You suddenly lose your vision.
  • You have sudden vision changes such as blurred vision, double vision, or seeing halos around lights.
  • You develop sudden, sharp eye pain.

Contact your healthcare provider if:

  • You have a fever.

Treatment for keratoconus

will depend on how severe it is. Treatment may include any of the following:

  • Eyeglasses help improve your vision.
  • Contact lenses are fitted to your eyes to help shape your cornea. This will help your eyes see and feel better. Wear contacts only as directed so that you do not cause more damage to your eyes. Ask for more information on how to insert and remove contacts carefully.
  • Surgery may be needed if other treatments do not work. Surgery can be used to fix the shape of your cornea so that you can see better. Surgery may be used to place permanent supports that will correct the shape of your cornea. Your cornea may need to be replaced if other treatments do not work.

Manage keratoconus:

  • Wear contacts or glasses as directed.
  • Wear sunglasses to protect your eyes from the sun. Too much time in the sun without eye protection may cause your condition to get worse.
