Abstract[English]
In certain embodiments, a surgical contact lens system for ophthalmic treatment with a laser beam includes a patient contact lens and a surgical contact lens. The patient contact lens reduces one or more refractive errors of the eye and has a concave surface and a convex surface. The concave surface is to be disposed outwardly from a cornea of an eye. The surgical contact lens has an eye end to be disposed outwardly from the convex surface of the patient contact lens. The surgical contact lens includes a frame and an optical component coupled to the frame. The patient contact lens reduces pressure from the surgical contact lens to reduce corneal folding of a posterior surface of the cornea. The optical component of the surgical contact lens and the patient contact lens transmit the laser beam to treat the eye.[French]
Dans certains modes de réalisation, un système de lentille de contact chirurgicale pour traitement ophtalmique avec un faisceau laser comprend une lentille de contact de patient et une lentille de contact chirurgicale. La lentille de contact de patient réduit une ou plusieurs erreurs de réfraction de l'œil et présente une surface concave et une surface convexe. La surface concave doit être disposée vers l'extérieur à partir d'une cornée d'un œil. La lentille de contact chirurgicale possède une extrémité d'œil à disposer vers l'extérieur à partir de la surface convexe de la lentille de contact de patient. La lentille de contact chirurgicale comprend un cadre et un composant optique couplé au cadre. La lentille de contact de patient réduit la pression à partir de la lentille de contact chirurgicale pour réduire le plissement cornéen d'une surface postérieure de la cornée. Le composant optique de la lentille de contact chirurgicale et la lentille de contact de patient transmettent le faisceau laser pour traiter l'œil.
