Title
(EN) METHOD AND DEVICE FOR WASHING OUT PSEUDOEXFOLIATION (PEX) MATERIAL USING A BALANCED SALT SOLUTION (BSS) IRRIGATION CANNULA IN COMBINATION WITH CATARACT SURGERY FOR LOWERING INTRAOCULAR PRESSURE
(FR) PROCÉDÉ ET DISPOSITIF DE LAVAGE DE SEUDOEXFOLIATION (PEX) PAR UNE CANULE D'IRRIGATION SOLUTION SALINE ÉQUILIBRÉE (BSS) COMBINÉS AVEC UNE OPÉRATION DE LA CATARACTE POUR BAISSER LA TENSION OCULAIRE
Abstract
(EN) The invention relates to a simple physiological technique intended for washing out pseudoexfoliation (PEX) material using BSS (balanced salt solution) on the trabecular meshwork and/or in the iridocorneal angle. Said technique is carried out after the time when an intraocular implant is placed in the capsular bag during cataract surgery. Said technique lowers the intraocular pressure. The washing is also applied with good results in cases of ocular hypertension without PEX material. The invention also relates to a cannula (1) having, on the front end (3) thereof, at least one opening (4) for creating a stream of balanced salt solution, or BSS, pointing in front of the cannula so as to wash out, clean away, and detach the masses of PEX material on the trabecular meshwork and/or in the iridocorneal angle. The invention also relates to the use of said method and device in the field of eye surgery.
(FR) L'invention concerne une technique physiologique et simple de lavage de pseudoexfoliation (PEX) par BSS (solution saline équilibrée) sur le trabéculum et/ou dans l'angle irido-cornéeen effectuée après le temps de la mise d'un implant intraoculaire dans le sac capsulaire d'une opération de la cataracte, cette technique faisant baisser la tension oculaire. Le lavage est appliqué avec un bon résultat également dans le cas de l'hypertension oculaire sans PEX. L'invention concerne aussi une canule (1) présentant à son extrémité avant (3) au moins une ouverture (4) pour créer un jet de solution saline équilibrée ou BSS pointant en avant de la canule pour laver, nettoyer et détacher les amas de PEX sur le trabéculum et/ou dans l'angle irido-cornéeen. Application dans le domaine de la chirurgie des yeux.
