Keratoconus

What is Keratoconus?

Keratoconus is a progressive eye disease that causes a thinning of the cornea, the clear front surface of the eye. The cornea is normally a round dome shape, but in the case of keratoconus, it becomes shaped like a cone. This bulging effect causes a distortion of vision.

Keratoconus is usually a bilateral condition but one eye may progress faster than the other. Familial occurrence has been noted although most cases show no definitive inheritance pattern.

Keratoconus Treatment with personalEYES

In the past, patients with keratoconus would have been told that they were not suitable for refractive surgery (LASIK). Today there are a number of possible options available.

Usually, the first step in keratoconus treatment is to correct the refractive error with glasses or hard contact lenses. This will help you to achieve adequate vision. As keratoconus progresses, the quality of your vision will deteriorate and contact lenses or glasses may no longer be satisfactory.

Many of our patients require a corneal transplant. However, kera ring prescription inserts are another option. Kera ring may be the best possible option to stabilise the cornea and improve vision.

A Toric Implantable Contact Lens (built-in astigmatism) is an option that can be used in those with mild keratoconus as long as the cornea is stable and good vision can be obtained with glasses. Corneas can be stabilised by Collagen Cross-Linking.

Stages of Keratoconus Treatment

  • Eyeglasses in the early stages.
  • Rigid contact lenses when eyeglasses do not work.
  • CXL – Corneal Collagen Cross-Linking with Riboflavin – increases the strength of the cornea to prevent progress.
  • Kera rings (Intracorneal rings) – when there is intolerance to contact lenses and when the condition continues to progress.
  • Corneal transplant in advanced stages – either a partial thickness (Deep Anterior Lamellar or DALK) or full thickness (Penetrating or PK).

We at personalEYES may be able to explore various procedures to help you become independent from contact lenses &/or glasses.
