Title (EN) RADIAL POCKET FORMING AND INSERT POSITIONING INSTRUMENTS, CORNEAL MARKER, AND METHOD FOR USING SAME
(FR) INSTRUMENTS DE FORMATION DE POCHES RADIALES ET DE POSITIONNEMENT D'INSERTS, MARQUEUR CORNEEN, ET PROCEDE D'UTILISATION DE CES INSTRUMENTS
Abstract:
(EN) Instruments and methods are provided which permit a surgeon to implant multiple radial inserts within a patient's cornea through one or more incisions made into the cornea. Instruments provided by the invention include a corneal marker, a radial pocket-forming instrument, and a positioning instrument. In one method provided by the invention, the surgeon uses the corneal marker to mark the patient's cornea with an incision mark, radial pocket marks, and circumferential channels marks simultaneously. The surgeon forms clockwise and counter-clockwise intrastromal circumferential channels through a single incision into the cornea, and then the surgeon inserts the radial pocket-forming instrument through the incision and into one of the circumferential channels to form radial pockets beneath the radial pocket marks. The surgeon inserts radial intrastromal inserts through the incision and into the circumferential channels and positions them within the radial pockets using the positioning instrument.
(FR) Cette invention se rapporte à des instruments et à des procédés qui permettent à un chirurgien d'implanter de multiples inserts radiaux dans la cornée d'un patient par une ou plusieurs incisions pratiquées dans la cornée. Les instruments faisant l'objet de cette invention sont constitués par un marqueur cornéen, un instrument de formation de poches radiales et un instrument de positionnement. Dans un procédé décrit par cette invention, le chirurgien utilise le marqueur cornéen pour marquer la cornée du patient au moyen d'une marque d'incision, au moyen de marques de poches radiales et au moyen de marques de canaux circonférentiels simultanément. Le chirurgien forme des canaux circonférentiels dans le stroma dans le sens des aiguilles d'une montre et dans le sens contraires à celui des aiguilles d'une montre par une seule incision pratiquée dans la cornée, et il insère ensuite l'instrument de formation de poches radiales par cette incision et dans l'un des canaux circonférentiels, afin de former des poches radiales sous les marques des poches radiales. Le chirurgien introduit les inserts radiaux du stroma par l'incision jusque dans les canaux circonférentiels et les positionne ensuite dans les poches radiales au moyen de l'instrument de positionnement.
