Title (EN) PHOTODISRUPTIVE LASER TREATMENT OF THE CRYSTALLINE LENS
(FR) TRAITEMENT LASER DE PHOTOCAUTÉRISATION DU CRISTALLIN
Abstract:
(EN) Apparatus and methods of treating a hard lens region of an eye with a laser where one method includes identifying a boundary of the hard lens region, selecting a laser-parameter to enable a photodisruptive procedure in the hard lens region and to control a spreading of bubbles in the hard lens region, modifying a mechanical property of a posterior portion of the hard lens region in a proximity of the identified boundary by the photodisruptive procedure, and modifying a mechanical property of a portion anterior to the modified posterior portion of the hard lens region by the photodisruptive procedure. The laser bubbles can be applied to form incisions which are non transverse to an axis of the eye and intersect the lens fibers.
(FR) L'invention concerne un appareil et des procédés de traitement au laser de la région rigide de la lentille d'un oeil, l'un des procédés consistant à identifier une frontière de la région rigide de la lentille, à sélectionner un paramètre du laser pour permettre l'exécution d'une intervention de photocautérisation dans la région rigide de la lentille et pour réguler la diffusion de bulles dans la région rigide de la lentille, à modifier une propriété mécanique de la partie postérieure de la région rigide de la lentille à proximité de la frontière identifiée par l'intervention de photocautérisation, et à modifier une propriété mécanique d'une partie antérieure de la partie postérieure modifiée de la région rigide de la lentille du fait de l'intervention de photocautérisation. Les bulles provoquées par le laser peuvent être appliquées à la formation d'incisions qui ne sont pas transversales par rapport à un axe de l'oeil et forment une intersection avec les fibres de la lentille.
