LASIK Induced Keratectasia Progression Prevented by Riboflavin and Ultraviolet-A Corneal Collagen Cross-Linking: Study

Riboflavin and ultraviolet-A corneal collagen cross linking can increase the bio-mechanical stability of the cornea and can halt and even partially reverse the progression of LASIK-induced keratectasia, according to a study by researchers in Switzerland & Germany.

Farhad Hafezi, MD, and colleagues in Switzerland and Germany performed corneal cross linking in one eye of 10 patients with previously undiagnosed forme fruste keratoconus or pellucid marginal corneal degeneration.

The researchers found that the cross-linking procedure stopped or partially reversed the progression of keratectasia in all cases, as demonstrated by reduced maximum keratometric readings and postoperative topographies, according to the study. Twelve months after crosslinking, all corneas were clear.

The study was published in the December issue of Journal of Cataract & Refractive Surgery.
