Corneal collagen cross-linking (CXL) is a technique which uses UV light and a photosensitizer to strengthen chemical bonds in the cornea. The goal of the treatment is to halt the progressive and irregular changes in corneal shape, known as an ectasia such as keratoconus. Also, some studies showed that CXL seems to be effective in improving visual acuity in eyes with progressive keratoconus with reducing corneal keratometry and cylinder. (Link)
What we call the « Cross-Linking Like » Effect (CXL Like Effect), corresponds to the same effect, ie to the reduction of cylinder and corneal keratometry, spontaneously, and only after immediate cessation of eye rubbing and/or correction of an unhealthy sleep position.
Indeed, we noticed that stopping eye rubbing, in most cases, ensured the stability of the keratoconus but also in some cases it led to a spontaneous regression of the keratoconus with a decrease of corneal cylinder and keratometry, without any other potentially harmful intervention for the eye.
We call this : The « Cross-Linking Like » Effect.
Here is a topography to illustrate this effect on a patient with keratoconus, with a differential map, after immediate cessation of eye rubbing on this eye.
