What Is Keratoconus?   


Depending on the severity of the disease the treatment may vary. 

Early stages

  • Eyeglasses or soft contact lenses may provide adequate vision correction.

Moderate stages

  • Rigid gas permeable (RGP) contact lenses
  • Hybrid contact lenses
  • Scleral contact lenses, which vault over the cornea and often provide excellent vision and comfort

Progressive keratoconus

  • Corneal collagen cross-linking (CXL): The only treatment proven to slow or stop progression. It uses riboflavin (vitamin B2) eye drops and ultraviolet (UV) light to strengthen the corneal tissue.

Advanced cases

  • Intracorneal ring segments (Intacs®) may help flatten the cornea and improve vision in selected patients.
  • Corneal transplantation (keratoplasty) may be recommended if the cornea becomes severely scarred or vision cannot be corrected with contact lenses. Fortunately, only a small percentage of patients require a transplant.

Can Keratoconus Be Prevented?

There is no known way to prevent keratoconus, but reducing excessive eye rubbing and managing allergies may help reduce stress on the cornea.

With modern treatments—especially early diagnosis and corneal cross-linking—most people with keratoconus can maintain good vision throughout their lives. Regular follow-up with an eye care professional is essential to monitor for progression and determine the most appropriate treatment.
