Corneal cross-linking is a treatment for keratoconus. This condition leads to weakening and thinning of the cornea over time. Without intervention, the cornea bulges into a cone shape, which distorts vision and makes it difficult to see clearly.
Corneal cross-linking, which was approved by the FDA in 2016, is the first treatment capable of halting the progression of keratoconus. This procedure has the potential to preserve sight and prevent the need for a corneal transplant, especially if cross-linking is performed early in the disease course.
