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]
There is limited evidence on the costs of corneal cross-linking, [90] a cost-effectiveness study estimated the costs of the total treatment for one person as £928 ($1,392 U.S.) in the UK National Health Service, [91] but this may be as high as $6,500 per eye in other countries. [92]
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.
Keratoconus, a progressive thinning of the cornea, is a common corneal disorder. Keratoconus occurring after refractive surgery is called Corneal Ectasia. It is believed that additional thinning of the cornea via refractive surgery may contribute to advancement of the disease [31] that may lead to the need for a corneal transplant.
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.
However, the cost of surgery is on the expensive side and can typically run up to $35,000 in the US. In order to obtain surgical treatment at a lower cost, many patients choose to get the treatment done from popular medical tourism destinations like India and Singapore [ citation needed ] where the cost of treatment may be as little as one ...

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.
