Corneal collagen cross linking "CCL"

About  CCL

Corneal collagen cross linking "CCL"

Keratoconus: is a disease that makes the cornea weak causing it to bulge outward. Most often, this bulging is in the lower half of the cornea and first presents progressive diminution of vision due to myopia (near sightedness) and astigmatism . In mild or early stages of keratoconus, eyeglasses may correct the vision.

The possible treatment option for Keratoconus

There is no cure for keratoconus and the only treatment is at improvement of the refractive errors induced by the disease.

 Until recently , the only therapeutic option for advanced cases with significant reduction of visual acuity was corneal transplantation (penetrating keratoplasty).

In the past few years, a new procedure has been developed that is supposed to stop the progression of keratoconus.

The Corneal Cross Linking treatment is performed in our center and is a one-time treatment
  • During the treatment, riboflavin eye drops are applied to the cornea, which is then activated by a special light. This is the process that has been shown in laboratory and clinical studies
  • to increase the amount of collagen cross-linking in the cornea and strengthen the cornea.
  • In published European studies, such treatments were proven safe and effective in patients.
  • After the treatment, a bandage contact lens is applied and a combination of a steroid and antibiotic drop is prescribed.
  • In approximately 80% of the patient’s regression of the keratoconus could be seen.
  • No unwanted side effects such as opacification of the lens or loss of endothelial cells has been reported.
  • Only during the first 2 to 3 months after the cross-linking a slight superficial corneal haze has been noticed. 
  • Generally, this minor haze disappears without any treatment, but a supportive therapy with soothing ointment or with a local steroid can be used.
  • In conclusion, early treatment with this procedure will enormously reduce the need for future corneal transplantation for many keratoconus patients.
  • It will be a great relief to our current shortage of available corneal tissues for transplantation.
  • The aim of this procedure is to stabilize the cornea and prevent the progression of keratoconus.
  • It is a non-invasive procedure that has been proven to strengthen the weak corneal structure in keratoconus.
  • This method works by inducing cross linking of the corneal collagen bundles, which are the natural “anchors” within the cornea.
  • These anchors are responsible for preventing the cornea from further bulging and becoming irregular (which is the cause of keratoconus).
