Abstract[English]
Disclosed herein is a method of performing ophthalmic surgery. The surgery includes positioning a patient interface relative to a patient's eye with the patient interface at least partially defining an interface chamber with the patient's eye. The interface chamber is filled with an immersion fluid. A fluid in an anterior chamber of the patient's eye is replaced with the immersion fluid, wherein the immersion fluid matches the refractive index of the cornea. A laser system is positioned relative to the patient interface. The laser system includes a laser source configured to generate a femtosecond laser beam and an optical delivery and scanner system in communication with the laser source to direct 3D scanned and focused laser beams through the patient interface and into the patient's eye.[French]
L'invention divulgue un procédé de réalisation d'une chirurgie ophtalmique. La chirurgie comprend le positionnement d'une interface patient par rapport à l'œil d'un patient, l'interface patient définissant au moins partiellement une chambre d'interface avec l'œil du patient. La chambre d'interface est remplie d'un fluide d'immersion. Un fluide dans une chambre antérieure de l'œil du patient est remplacé par le fluide d'immersion, le fluide d'immersion correspondant à l'indice de réfraction de la cornée. Un système laser est positionné par rapport à l'interface patient. Le système laser comprend une source laser conçue pour générer un faisceau laser femtoseconde et un système de distribution et de dispositif de balayage optique en communication avec la source laser pour diriger des faisceaux laser balayés et focalisés en 3D à travers l'interface patient et dans l'œil du patient.
