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]
The National Eye Institute reports keratoconus is the most common corneal dystrophy in the United States, affecting about one in 2,000 Americans, [77] [78] but some reports place the figure as high as one in 500. [79] In the pediatric populations, ages three to 18, the prevalence of keratoconus was found to be as high as one in 334 children. [80]
Peter S. Hersh is an American ophthalmologist, researcher, and specialist in LASIK eye surgery, keratoconus, and diseases of the cornea.He co-authored the article in the journal Ophthalmology that presented the results of the study that led to the first approval by the U.S. Food and Drug Administration (FDA) of the excimer laser for the correction of nearsightedness in the United States.
Pellucid marginal degeneration is diagnosed by corneal topography. 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.
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. [3]
Corneal topography, also known as photokeratoscopy or videokeratography, is a non-invasive medical imaging technique for mapping the anterior curvature of the cornea, the outer structure of the eye. Since the cornea is normally responsible for some 70% of the eye's refractive power , [ 1 ] its topography is of critical importance in determining ...

Diaminobenzidine stains keratocytes in the cross-section of cornea. From Mootha et al., 2009. [14] Keratocytes may play a role in different corneal disorders. According to comparative research, their functions drastically diverge from the norm in keratoconus, the most frequent form of corneal dystrophy.
