keratoconus

Keratoconus is a progressive eye condition where the normally round cornea (the clear, dome-shaped surface at the front of the eye) thins and bulges into a cone-like shape. This irregular shape distorts light as it enters the eye, leading to vision problems.

The condition typically begins in the teenage years or early twenties and can progress slowly over several years. In some cases, it may stabilize on its own, but in others, it can continue to worsen.

Symptoms can include blurred or distorted vision, due to the irregular shape of the cornea, light sensitivity, seeing halos or streaks around lights and frequently having changes to your prescription with your spectacles or contact lenses.

Keratoconus requires ongoing management and monitoring by an eye care professional. Our Optometrists are able to tailor treatment for you as the condition progresses and to ensure the best possible visual outcomes.

 FAQs

  • The exact cause of keratoconus is not fully understood, but genetic factors, environmental factors, and biochemical changes in the cornea may contribute.

    It is sometimes associated with conditions like allergies and excessive eye rubbing.

    • Spectacles or Contact Lenses: Early stages can often be managed with corrective lenses, especially specialized contact lenses designed for keratoconus.

    • Corneal Cross-Linking (CXL): A treatment that strengthens the corneal tissue using riboflavin (vitamin B2) and ultraviolet (UV) light. This can help slow or halt the progression of the disease.

    • Intacs: Small, semi-circular inserts implanted into the cornea to help reshape it and improve vision.

    • Corneal Transplant: In severe cases, a corneal transplant (keratoplasty) may be needed to replace the damaged cornea with a healthy one from a donor.

  • There is no cure for keratoconus, but there are several effective treatments options available that can manage and often significantly improve the condition.

    While some treatments can significantly improve quality of life and vision for many people with keratoconus, they do not cure the condition outright. Management of keratoconus often involves ongoing monitoring and adjustment of treatment as needed. Regular follow-ups with an eye care professional are essential to address changes in the condition and to adapt treatment plans accordingly.
