Title
(EN) ANTIMICROBIAL CONTACT LENS CASE
(FR) BOITIER ANTIMICROBIEN POUR LENTILLE DE CONTACT
Abstract
(EN)
The present invention relates to an antimicrobial contact lens case and an ophthalmic solution container that are comprised of an antimicrobial polymeric resin and have antimicrobial surfaces, but which do not contaminate the lens or solution with antimicrobial agent. The present invention provides a novel antimicrobial contact lens container which is adapted to hold one or more contact lenses and ophthalmic solution. The contact lens container is made from a polymeric material containing zeolite which has ion-exchanged thereon silver ions in an amount from about 0.1 to 5 wt.% of the zeolite and ammonium ions in an amount from about 0.5 to 15 wt.% of the zeolite. The zeolite is present in an amount from about 0.5 to 5 wt. % of the polymeric material. The contact lens container of the invention does not leach ions from the polymeric material into the ophthalmic solution in a substantially antimicrobial amount.

La présente invention concerne un boîtier antimicrobien pour lentille de contact et un contenant de solution ophtalmique, qui sont constitués d'une résine polymérique antimicrobienne et présentent des surfaces antimicrobiennes, mais utilisent un agent antimicrobien incapable de contaminer la lentille ou la solution. L'invention concerne également un nouveau boîtier antimicrobien pour lentille de contact conçu pour contenir une ou plusieurs lentilles de contact et une solution ophtalmique. Le boîtier pour lentille de contact est fabriqué avec un matériau polymérique contenant une zéolite dans laquelle intervient un échange ionique d'une quantité d'ions d'argent représentant environ 0,1 à 5 % en poids de la zéolite et d'une quantité d'ions d'ammonium représentant environ 0,5 à 15 % en poids de la zéolite. La zéolite constitue environ 0,5 à 15 % en poids du matériau polymérique. Le boîtier pour lentille de contact de l'invention ne lixivie pas les ions d'argent du matériau polymérique dans la solution ophtalmique dans des quantités sensiblement antimicrobiennes.
