Title (EN) SILICONE HYDROGEL CONTACT LENSES
(FR) LENTILLES DE CONTACT EN HYDROGEL DE SILICONE
Abstract: front page image
(EN)Silicone hydrogel contact lenses are described. The lenses are derived from a polymerizable composition including 30-60 unit parts by weight of a hydrophilic monomer(s) having one N-vinyl group, 10 to 50 unit parts by weight of 2-hydroxyethyl methacrylate (HEMA), and a first siloxane monomer component comprising a siloxane monomer of formula (1) as described herein or a siloxane monomer of formula (2) as described herein or a siloxane monomer of formula (3) as described herein or any combination thereof, where the total amount of siloxane monomer(s) present in the polymerizable composition is from 15 to 40 unit parts by weight. Batches of silicone hydrogel contact lenses and methods of making silicone hydrogel contact lenses are also described.
(FR)L'invention concerne des lentilles de contact en hydrogel de silicone. Les lentilles sont obtenues à partir d'une composition polymérisable comprenant de 30 à 60 parties en poids de motifs d'un ou de plusieurs monomères hydrophiles contenant un groupe N-vinyle, de 10 à 50 parties en poids de motifs de méthacrylate de 2-hydroxyéthyle (HEMA), et un premier composant monomère de siloxane comprenant un monomère de siloxane de formule (1) telle que décrite ici ou un monomère de siloxane de formule (2) telle que décrite ici ou un monomère de siloxane de formule (3) telle que décrite ici, ou une combinaison quelconque de ceux-ci, la quantité totale du ou des monomères de siloxane présents dans la composition polymérisable allant de 15 à 40 parties en poids de motifs. L'invention concerne également des lots de lentilles de contact en hydrogel de silicone ainsi que des procédés de fabrication de lentilles de contact en hydrogel de silicone.
