CXL – Corneal Crosslinking

CXL stands for corneal cross-linking and is a surgical method employed in case of eye diseases that entail a reduction of the cornea or a progressive deterioration of vision. Corneal cross-linking helps to stabilise eye diseases such as keratoconus.

CXL procedure

The procedure to stabilize the cornea – corneal cross-linking – consists of two steps. In a first step, riboflavin (vitamin B2) is applied to the eye. Subsequently, the cornea is exposed to ultraviolet light with a wavelength of 365 nanometres. The aim of this procedure is to enhance the stability of the cornea through the formation of new crosslinks between the collagen fibres of the cornea. In this way, the gentle and safe CXL treatment can help to avoid a transplantation of the cornea (keratoplasty).
