If vision recovery is not satisfactory after corneal cross-linking, corneal transplantation can be performed to provide further relief. The principle of corneal collagen cross-linking is to use riboflavin as a photosensitizing agent and a special wavelength of ultraviolet light to irradiate the cornea locally, stimulating the collagen fibers to cross-link and improve the biomechanical properties of the cornea, which can effectively control the progression of corneal keratopathy, stabilize the vision, and avoid the complications associated with corneal transplantation. Corneal cross-linking can increase the strength of the cornea, but if the patient’s condition is still progressing after this treatment, or if the results are unsatisfactory, a corneal transplant can be used. Corneal transplants can be performed if the disease is still progressing or the treatment is not effective after the corneal cross-linking procedure. Specific treatment matters need to go to the eye department of a regular hospital after consultation, the professional doctor for evaluation, patients are recommended to review the eye condition at any time.
