Keratoconus cross linking surgery is meant to slow down the disease progression. This particular treatment is suggested for patient with keratoconus in its initial phases (e.g. fruste keratoconus) to prevent it from worsening.
Cross-linking surgery should increase the links between collagen fibrils that cornea is made of, in order to make it stronger and less deformable. Cross Linking surgery lasts about 1 hour: cornea is numbed with a substance called riboflavin; after that, the cornea is lighted up with A ultraviolet rays.
Cross linking with riboflavin can be performed removing the corneal epithelium (epi-OFF) or leaving it intact (epi-ON): this two procedures both have advantages and disadvanages that should be considered in every single case. After cross-linking surgery, it is possible to experience a certain degree of discomfort for at least a couple of days.
Cross linking surgery result becomes noticeable after a few weeks or months and an improvements can be experienced even 1 year after this procedure.
Thegoal of the keratoconus cross-linking is not to improve vision, but to prevent it from worsening because the keratoconus progression
Dr. Badalà performs keratoconus cross linking treatments in Milan and Catania.
Cross linking complications could be ultraviolet rays damages to cornea, crystalline lens or retina; this is why cross linking should be avoid when the cornea is too thin and keratoconus in an advanced phase.
