Top 10 questions about cross-linkingKeratoconus treatment has changed much over the past several years. Avedro’s U.S. Food and Drug Administration (FDA) approval of corneal cross-linking has given more patients hope for better vision.
Epi-on CXL: Safe, effective option for treating thin corneasPatients with thin corneas as the result of keratoconus, ectasia following LASIK, or pellucid marginal degeneration can safely undergo epithelial-on collagen crosslinking with pulsed UV light and achieve visual benefits from the procedure.
Photoactivation holds promise for keratitis treatment
Photoactivation holds promise for keratitis treatmentThe same photoactivation process used in collagen cross-linking for keratoconus can kill bacteria without the need for the oxygen responsible for the biomechanical effects, potentially pointing toward better treatments for keratitis, according to Olivier Richoz, MD, PhD.
A 12-year-old with a perplexing rashThe parents of a healthy 12-year-old boy bring him for a second opinion. He was diagnosed with pityriasis rosea 6 months ago, and new lesions, which are occasionally a little itchy, keep coming. What is causing these new lesions?
New clue to how sunlight harms young eyesLong-term exposure to ultraviolet radiation in sunlight is known to increase the risk of cataracts later in life. A new study suggests how that might happen.
Examining advances in EPI-ON CXL for keratoconusEpithelial-on crosslinking seems to be effective and safe for treating keratoconus as the result of the combination of a new formulation of riboflavin with a higher level of ultraviolet light. This technique resulted in improvements in corneal shape, uncorrected visual acuity, and best spectacle-corrected visual acuity.
