Stop keratoconus in its tracks with corneal cross-linking

A great solution to stop the progression of keratoconus

Corneal cross-linking suitability criteria

  • In cases of progressive keratoconus, corneal cross-linking (CXL) has become an important mode of treatment.3https://www.webmd.com/eye-health/corneal-cross-linking-for-keratoconus
  • CXL can halt the progression of the disease and is very low risk 4https://www.aao.org/eyenet/article/cxl-road-ahead. The treatment is not a cure although some reversal of the visual effects of the disease is frequently seen. Best results are achieved before the disease becomes too advanced.

  • During the CXL procedure UV light is used to strengthen the corneal collagen. This occurs at a cellular level by formation of “cross-links” or bonds between the collagen layers of the cornea. Riboflavin drops are used during the procedure which act as an absorber and protect the remaining layers of the eye from UV.

  • Advantages are:
    • Halting of keratoconus progression5https://www.webmd.com/eye-health/corneal-cross-linking-for-keratoconus
    • Preserving vision
  • Disadvantages
    • If the keratoconus is too advanced then CXL cannot reverse the keratoconus.

The risks include, but are not limited to the following:

  • Infection
  • Delays in re-growth of the surface cells resulting in a foreign body sensation on occasion requiring more frequent and prolonged use of lubricant drops.
  • Corneal haze which usually clear by 3-6 months.
  • Corneal swelling.

At this stage, the duration of clinical studies and the number of treated cases is insufficient to be able to fully profile the longer-term risks of the procedure beyond 15 years.

  • Kerarings – tiny plastic segments designed to be implanted in the cornea and reshape the cornea into a better shape.
  • Topography-guided PRK – a laser-based treatment where the aim is to regularise the surface of the cornea to allow better fitting of glasses or contact lenses post-operatively.
  • Corneal transplantation – a treatment for advanced cases of keratoconus ​​which involves removing all (penetrating keratoplasty) or part of the cornea (deep anterior lamellar keratoplasty) that is cloudy or abnormally shaped and replacing it with a healthy donor cornea.

  • The procedure is performed under local anesthetic drops and requires 30-40 minutes.
  • A central area of the surface cells of the cornea are removed to allow the Riboflavin to penetrate.
  • Riboflavin drops are applied for 30 minutes.
  • After confirming that the cornea is of sufficient thickness the UV light is applied for 10 minutes.
  • The cornea is then covered with a bandage contact lens (BCL) and drops are instilled.
  • The corneal surface cells re-grow after 3-5 days at which time there will be an appointment scheduled at IVISION LASER for BCL removal.

  • Our results show 100% efficacy at stabilising keratoconus at 2 years post-treatment. Approximately half of the patients experience an improvement in their astigmatism and contact lens fitting.

Corneal collagen cross-linking is a procedure that aims to strengthen the cornea in order to slow or halt the progression of keratoconus. It achieves this through a chemical reaction using a combination of riboflavin (vitamin B2) and ultraviolet (UVA) light to strengthen the cross-links between the collagen fibres within the stroma layer of the cornea.

This post encompasses all things keratoconus, from symptoms, diagnosis and signs, to treatments involving cross-linking and eligibility. Click here for more information.

Corneal cross-linking is a minimally invasive outpatient procedure designed to treat progressive keratoconus (and, sometimes, other conditions that cause a similar weakening of the cornea).

The two basic types of corneal cross-linking are:

  • Epithelium-off cross-linking. The thin outer layer (epithelium) of the cornea is removed to allow the liquid riboflavin to penetrate the deeper corneal tissue with ease.
  • Epithelium-on cross-linking. The protective corneal epithelium is left intact, making it a less invasive procedure than cross-linking with epithelium removal.
