Corneal cross-linking (CXL) with riboflavin (vitamin B 2) and UV-A light is a surgical treatment for corneal ectasia such as keratoconus, PMD, and post-LASIK ectasia. It is used in an attempt to make the cornea stronger.
In 2016, however, the FDA approved cross-linking surgery as a treatment for keratoconus and recommended that a registry system should be set-up to evaluate the long-term treatment effect. [ 9 ] [ 70 ] The Save Sight Keratoconus Registry is an international database of keratoconus patients that is tracking outcomes of cross-linking in patients ...
In 2002, Hafezi's clinical and research interests turned to the cornea. He became a corneal specialist, and his work helped develop the principles of corneal collagen cross-linking (CXL) and translate CXL from a laboratory into a clinical setting, initially for the treatment of keratoconus. Hafezi's combination of basic science knowledge ...
Corneal pachymetry may be useful in confirming the diagnosis. Treatment usually consists of vision correction with eyeglasses or contact lenses. Intacs implants, corneal collagen cross-linking, and corneal transplant surgery are additional options. Surgery is reserved for individuals who do not tolerate contact lenses.
Cross-linking may refer to Cross-link , a chemical bond of one polymer chain to another Corneal collagen cross-linking , a parasurgical treatment for corneal ectasia and keratoconus
Treatment options include contact lenses and intrastromal corneal ring segments for correcting refractive errors caused by irregular corneal surface, [7] [8] corneal collagen cross-linking to strengthen a weak and ectatic cornea, [9] or corneal transplant for advanced cases.

When cross-linking is performed only after the cornea becomes distorted, vision remains blurry even though the disease is stabilised. As a result, combining corneal collagen cross-linking with LASIK ('LASIK Xtra') aims to strengthen the cornea at the point of surgery and may be useful in cases where a very thin cornea is expected after the ...
