STRUCTURE DE PARTIE D'INCISION PRÉSENTANT DES PARTIES DE RENFORCEMENT, DE FAÇON À ÊTRE FORMÉES SUR LA CORNÉE, POUR RETIRER UN LENTICULE INCISÉ PAR CHIRURGIE DE CORRECTION VISUELLE
The present invention relates to an incision portion structure, having reinforcement portions to be formed on a cornea, for removing a lenticule incised according to an eye sight correction surgery. Disclosed is an eye sight correction surgery in which a flap surface and a lenticule surface, which have a continuous spiral-shaped incision line, are formed to be spaced from each other in the corneal parenchyma, while a laser beam three-dimensionally displaces a focal point location and forms a dense spiral toward the center of the cornea or outward from the center thereof, such that a lenticule is incised in a three-dimensional form from the corneal parenchyma by crossing the outer periphery of the lenticule surface with each other at the inside of the outer periphery of the flap surface, and the incised lenticule is expelled to the outside through the incision portion formed on the cornea, and thus a refractive error is corrected, wherein the incision portion includes: an incision entry portion to be formed by the laser beam on the cornea surface in proximity to the outer periphery of the flap surface； and an incision tunnel extended toward the corneal parenchyma from the incision entry portion and of which a front end portion is connected to the flap surface, and the front end portion of the incision tunnel is connected on any one side incision line of the flap surface and reinforcement portions, which are areas in which laser beams are not emitted, are symmetrically formed on outer surfaces facing each other in a length direction of the incision tunnel on the incision line.La présente invention concerne une structure de partie d'incision présentant des parties de renforcement destinées à être formées sur une cornée, pour retirer un lenticule incisé par chirurgie de correction visuelle. La présente invention concerne une chirurgie de correction visuelle au cours de laquelle une surface de volet et une surface de lenticule, qui présente une ligne d'incision en forme
