Corneal collagen cross-linking strengthens the cornea by allowing it to re-form new cross-links between the collagen fibers. These new cross-links help strengthen the cornea which stops the thinning process and further loss of vision. This procedure can be used to slow or stop the progression of degenerative corneal conditions such as keratoconus and ectasia. A no-touch 15 minute screening is available to assess patients for suitability.
