Keralux disposable Micro-CXL can be used for any crosslinking protocol including conventional Epi-off and Epi-on.

This technology allows an optimal energy transfer to the cornea across the irradiated area. Neither an irregular corneal shape nor eye or head movement affect the treatment result. Also, the distance between the eye and the light source, which is crucial for guaranteeing the right irradiation of the cornea, is perfectly maintained throughout the entire treatment. Keralux disposable Micro-CXL is  a milestone with respect to safety and effectivity of corneal crosslinking.

The KERALUX treatment is safe and effective as well as quick and easy to perform. The high-end micro-technology allows for an automated irradiation process.



Conventional Crosslinking

In conventional crosslinking, failure rates of up to 15% are reported. In these cases, the disease progresses despite therapy.

One reason for the high treatment failure rate is likely to be the fact that the energy transfer to the cornea is often insufficient. Due to the irregular shape of the keratoconus cornea (red curvature in the right picture), the energy transfer to the cornea varies across the irradiated area (blue area in the right picture). The desired intensity only occurs at the apex. The effective intensity in the pathologic area, i.e. at the steep slopes of the cone, is reduced.



KERALUX Crosslinking

KERALUX has a closed irradiation channel. This irradiation channel rests right on the eye and is lined inside with a diffuse UV-A reflector. The UV-light source emits light rays with a defined opening angel. As a result, diffuse multiple reflections occur on the inner wall of the irradiation channel. The light strikes the cornea from all sides. The result is a homogeneous intensity distribution over the irradiated area of the cornea which is independent from the local steepness (blue intensity area in the right picture). As KERALUX moves with the eye the treatment is also independent from eye movements. The closed tubular irradiation channel also protects the environment e.g. the second eye of the patient or medical staff from secondary radiation.
