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. According to a 2015 Cochrane review, there is insufficient evidence to determine if it is useful in keratoconus. [2]
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 ...
There is evidence suggesting corneal collagen cross-linking may be beneficial for patients with pellucid marginal degeneration. [ 12 ] [ 13 ] [ 14 ] Research shows some promising results by combining collagen cross linking with photorefractive keratectomy , or with topography -guided transepithelial surface ablation .
Keratoconus, a progressive, noninflammatory, bilateral, asymmetric disease, characterized by paraxial stromal thinning and weakening that leads to corneal surface distortion. [ 2 ] Keratoglobus , a rare noninflammatory corneal thinning disorder, characterised by generalised thinning and globular protrusion of the cornea.
It is, in fact, one of the exams the patients have to undergo prior to the Cross-linking and the Mini Asymmetric Radial Keratotomy (M.A.R.K.). For example, the KISA% index (keratometry, I-S, skew percentage, astigmatism) is used to arrive at a diagnosis of keratoconus , to screen the suspect keratoconic patients and analyse the degree of ...
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.
Donors can be of any age, as is shown in the case of Janis Babson, who donated her eyes after dying at the age of 10. [ 1 ] [ 2 ] Corneal transplantation is performed when medicines, keratoconus conservative surgery and cross-linking can no longer heal the cornea .
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
