Title
(EN) SWITCHABLE VISCOELASTIC SYSTEMS CONTAINING GALACTOMANNAN POLYMERS AND BORATE
(FR) SYSTEMES VISCOELASTIQUES TRANSFORMABLES CONTENANT DES POLYMERES DE GALACTOMANNAN ET DU BORATE
Abstract
(EN) The present invention is directed to viscoelastic systems comprising a combination of a galactomannan polysaccharide containing composition and borate containing composition. The two compositions gel or partially gel upon combination. The present invention also discloses methods of using the systems during surgery and, in particular, eye surgery.
(FR) L'invention porte sur des systèmes viscoélastiques comprenant une combinaison de polysaccharides de galactomannan et du borate, qui se transforment partiellement ou totalement en gel lors de leur combinaison. L'invention porte également sur des procédés d'utilisation desdits systèmes à des fins de chirurgie et en particulier de chirurgie de l'oeil.
