Although cross-linking cannot restore lost vision due to keratoconus, it prevents future vision loss.Sudden vision loss occurs quickly, over a period of a few seconds or minutes to a few days. It involves using riboflavin (vitamin B12) drops and UV radiation on the cornea, to strengthen the collagen fibres in the cornea. The results with transplantation are usually excellent for keratoconus.Ĭollagen cross-linking is a newer treatment that slows or stops the progression of keratoconus. Corneal transplantation involves removing the diseased area of cornea and replacing it with a healthy, donor cornea. In advanced keratoconus, when glasses or contact lenses no longer can improve the vision, a corneal transplant may be necessary. As the disease progresses special hard contact lenses (rigid gas permeable contact lenses) may be required. In the early stages of the diseases, the vision may be corrected with glasses or soft contact lenses.
