Corneal collagen cross-linking (CXL) in thin corneas
Corneal collagen cross-linking (CXL) is a therapeutic procedure aiming at increasing the corneal stiffness in the keratoconus eyes by induction of cross-links within the extracellular matrix. It is achieved by ultraviolet-A (370 nm) irradiation of the cornea after saturation with the photosensitizer riboflavin. In the conventional CXL protocol, a minimum de-epithelialized corneal thickness of 4...
متن کاملTransepithelial corneal collagen cross-linking in ultrathin keratoconic corneas
BACKGROUND The purpose of this paper was to report the results of transepithelial corneal collagen cross-linking (CXL) with modified riboflavin and ultraviolet A irradiation in patients affected by keratoconus, each with thinnest pachymetry values of less than 400 μm (with epithelium) and not treatable using standard de-epithelialization techniques. METHODS Sixteen patients affected by progre...
متن کاملScheimpflug imaging of corneas after collagen cross-linking.
PURPOSE To compare geometrical shape factors of keratoconus corneas after cross-linking (CXL) by means of Scheimpflug imaging with those of untreated fellow eyes. SETTING Institut für Refraktive und Ophthalmo-Chirurgie, Zürich, Switzerland. METHODS Scheimpflug imaging of the anterior segments was performed with the Pentacam (Oculus, Wetzlar, Germany) in 21 patients with progressive keratect...
متن کاملMultiphoton microscopy of ex vivo corneas after collagen cross-linking.
PURPOSE To investigate changes in the morphology of the corneal stroma after collagen cross-linking (CXL) treatment in bovine and porcine eyes using a nonlinear microscope providing both two-photon excitation fluorescence (TPEF) and second harmonic generation (SHG) corneal images. METHODS Freshly enucleated eyes were imaged using a tomographic nonlinear imaging method that was highly suitable...
متن کاملCustomized epithelial debridement for thin ectatic corneas undergoing corneal cross-linking: epithelial island cross-linking technique
Thin corneas with a minimum corneal thickness less than 400 μm after epithelial removal represent a contraindication to standard epithelium-off cross-linking (CXL) treatment due to a significant endothelial cell density decrease and potentiality of permanent haze development. Preoperative swelling of the cornea with hypoosmolar riboflavin solutions broadens the spectrum of CXL indications to th...
