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]
Corneal collagen cross-linking is a developing treatment that aims to strengthen the cornea, however, according to a 2015 Cochrane review, there is insufficient evidence to determine if it is useful in keratoconus. [69]
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 ...
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.
[1] [2] Corneal transplantation is performed when medicines, keratoconus conservative surgery and cross-linking can no longer heal the cornea. This surgical procedure usually treats corneal blindness, [3] [4] with success rates of at least 41% as of 2021. [5] [6] [7]
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.
Cohen is a North American pioneer in the treatment of keratoconus and ectatic diseases of the cornea. As a method of treating the underlying disease and reversing the damage that has previously occurred, he began performing corneal collagen cross linking combined with topography guided excimer laser ablations in 2009.
Keratoconus is the most common form of corneal ectasia, a progressive thinning of the cornea. The condition is treated by corneal collagen cross-linking, which increases corneal stiffness. Cross-linking is achieved by applying a topical riboflavin solution to the cornea, which is then exposed to ultraviolet A light. [20] [21]
