Corneal crosslinking is a treatment option for people who have keratoconus conditions. However, there are certain contraindications for this procedure, including:
Less than 400 microns of corneal thickness is not suitable for a standard treatment protocol
History of herpetic infection is also a contraindication as the procedure can lead to viral reactivation
Repeated infections
Opacification or severe scarring in the cornea
Poor epithelial wound healing history
Severe eye surface disease such as dry eye
Certain types of autoimmune disorders
