Abstract
(EN)
Femtosecond laser may be used to crosslink corneal collagen in absence of photosensitizers to correct refractive errors and enhance corneal mechanical properties of tissues, such as the cornea. The treatment time is reduced by defining treatment layers in the tissue being treated and focusing the laser at selected layers to effect treatment at the multiple layers. Volumetric exposure to the laser has been executed by treating multiple planar areas at varying depths, measured from the surface of the treated tissue.
(FR)
Un laser femtoseconde peut être utilisé pour réticuler le collagène cornéen en l'absence de photosensibilisants pour corriger des erreurs de réfraction et améliorer les propriétés mécaniques cornéennes de tissus, tels que la cornée. Le temps de traitement est réduit en définissant des couches de traitement dans le tissu traité et en focalisant le laser au niveau des couches sélectionnées pour effectuer un traitement au niveau des multiples couches. Une exposition volumétrique au laser a été exécutée en traitant de multiples zones planes à des profondeurs variables, mesurées à partir de la surface du tissu traité.
