Corneal cross-linking (CXL) with riboflavin (vitamin B 2) and UV-A light is a surgical treatment for corneal ectasia such as keratoconus, [2] PMD, and post-LASIK ectasia. It is used in an attempt to make the cornea stronger. According to a 2015 Cochrane review, there is insufficient evidence to determine if it is useful in keratoconus. [3]
They are now mostly used to treat mild to moderate keratoconus. [1] Intrastromal corneal rings were approved in 2004 by the Food and Drug Administration for people with keratoconus who cannot adequately correct their vision with glasses or contact lenses, and for whom corneal transplant is the only other option.

Therefore, keratoconus is a contraindication to refractive surgery. Corneal topography and pachymetry are used to screen for abnormal corneas. Furthermore, some people's eye shape may not permit effective refractive surgery without removing excessive amounts of corneal tissue. Those considering laser eye surgery should have a full eye examination.
Approximately half of infections occur within 2 weeks of surgery, but delayed infection do occur up to a year after surgery. [15] Staphylococcus aureus was the most commonly identified bacteria for rapid onset and Pseudomonas aeruginosa was the most common identified bacteria for delayed onset.
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. [ 10 ] [ 71 ] The Save Sight Keratoconus Registry is an international database of keratoconus patients that is tracking outcomes of cross-linking in patients ...

Corneal transplantation, also known as corneal grafting, is a surgical procedure where a damaged or diseased cornea is replaced by donated corneal tissue (the graft). When the entire cornea is replaced it is known as penetrating keratoplasty and when only part of the cornea is replaced it is known as lamellar keratoplasty.
According to the Mayo Clinic, surgery was previously done to relieve pressure on the facial nerve, but now it's not recommended due to risks of facial nerve injury and permanent hearing loss ...
