Abstract[English]
The invention provides a method for producing embedded contact lenses involving a mold set in a two-curing-step process and a fast-curing SiHy lens formulation. The mold set consists of three mold halves, one of which is used twice, the first time for molding an insert from an insert-forming composition and the second time for an embedded contact lens with the molded insert embedded therein from the fast curing SiHy lens formulation that comprises a N,N-dialkylacrylamide, a hydrophilic (meth)acrylamido monomer, and a polysiloxane vinylic crosslinker and being free of any siloxane-containing vinylic monomer.[French]
L'invention concerne un procédé de production de lentilles de contact intégrées impliquant un ensemble de moules dans un procédé à deux étapes de durcissement et une formulation de lentille SiHy à durcissement rapide. L'ensemble de moules est constitué de trois moitiés de moule, dont l'une est utilisée deux fois, la première fois pour mouler un insert à partir d'une composition de formation d'insert et la seconde fois pour une lentille de contact intégrée avec l'insert moulé intégré dans celle-ci à partir de la formulation de lentille SiHy à durcissement rapide qui comprend un N,N-dialkylacrylamide, un monomère (méth)acrylamido hydrophile, et un agent de réticulation vinylique de polysiloxane et étant exempte de tout monomère vinylique contenant du siloxane.
