Abstract[English]
In one aspect, the present disclosure relates to ophthalmic devices comprising a hyper gas-permeable material. The present disclosure further relates to hyper gas-permeable polymers, materials, products comprising the polymers or materials, and methods of making thereof. In one aspect, the instant disclosure provides polymer materials that have required Dk number while not requiring PFAS component. In one aspect, the polymer materials provides oxygen permeability by, in part, increasing gas diffusivity. In some embodiments, the polymer materials comprise percolated channels.[French]
Selon un aspect, la présente invention concerne des dispositifs ophtalmiques comprenant un matériau hyper-perméable au gaz. La présente divulgation concerne en outre des polymères, des matériaux, des produits comprenant les polymères ou matériaux hyper-perméables aux gaz, et leurs procédés de fabrication. Selon un aspect, la présente invention concerne des matériaux polymères qui présentent un nombre Dk requis sans nécessiter de composant PFAS. Selon un aspect, les matériaux polymères fournissent une perméabilité à l'oxygène en augmentant, en partie, la diffusivité gazeuse. Dans certains modes de réalisation, les matériaux polymères comprennent des canaux percolés.
