Abstract[English]
Provided is a process for making an ophthalmic devices and ophthalmic devices resulting from the process. The process comprises: (a) providing a first reactive composition containing: (i) a polymerization initiator that is capable, upon a first activation, of forming two or more free radical groups, at least one of which is further activatable by subsequent activation; (ii) one or more ethylenically unsaturated compounds; and (iii) a crosslinker; (b) subjecting the first reactive composition to a first activation step such that the first reactive composition polymerizes therein to form a crosslinked substrate network containing a covalently bound activatable free radical initiator; (c) contacting the crosslinked substrate network with a grafting composition containing a shrinking agent and one or more ethylenically unsaturated compounds; and (d) activating the covalently bound activatable free radical initiator of the crosslinked substrate network such that the grafting composition polymerizes therein with the crosslinked substrate network.[French]
L'invention concerne un procédé de fabrication de dispositifs ophtalmiques et des dispositifs ophtalmiques résultant du procédé. Le procédé comprend les opérations suivantes consistant à : (a) prendre une première composition réactive contenant : (i) un initiateur de polymérisation pouvant, lors d'une première activation, former au moins deux groupes de radicaux libres, dont au moins un peut être activé davantage par une activation ultérieure ; (ii) un ou plusieurs composés éthyléniquement insaturés ; et (iii) un agent de réticulation ; (b) soumettre la première composition réactive à une première étape d'activation de telle sorte que la première composition réactive se polymérise pour former un réseau de substrat réticulé contenant un initiateur de radicaux libres activable lié par covalence ; (c) mettre en contact le réseau de substrat réticulé avec une composition de greffage contenant un agent de rétraction et un ou plusieurs composés éthyléniquement insaturés ; et (d) activer l'initiateur de radicaux activable lié par covalence du réseau de substrat réticulé de telle sorte que la composition de greffage se polymérise avec le réseau de substrat réticulé.
