Corneal cross-linking (CXL) is an in-office eye procedure that strengthens the cornea if it's been weakened by keratoconus, other corneal disease, or (rarely) a complication of LASIK surgery. Alternative and brand names for the procedure include corneal crosslinking, corneal collagen crosslinking, C3-R, CCL and KXL.ayers of the cornea. Corneal crosslinking strengthens bonds in the stroma of the cornea, which is the layer from which tissue is removed during LASIK surgery. The crosslinking procedure takes 60 to 90 minutes in most cases.
