Abstract

MATERIAIS DE INSERTO DE SILOXANO COM ALTO ÍNDICE DE REFRAÇÃO PARA LENTES DE CONTATO INCORPORADAS. A presente invenção se refere, em geral, a um inserto para ser incorporado em uma lente de contato de hidrogel de silicone. O inserto é feito de materiais reticulados que são rígidos em estado seco à temperatura ambiente (de cerca de 22 °C a cerca de 26 °C), têm uma alta permeabilidade a oxigênio e um alto índice de refração em estado totalmente hidratado. Tais materiais são úteis para produzir insertos em lentes de contato incorporadas para corrigir astigmatismo da córnea, presbiopia e lentes de daltonismo e para conferir características fotocrômicas às lentes. A invenção também se refere a um método para produzir lentes de contato de hidrogel de silicone incorporadas que compreendem um inserto da invenção nas mesmas e a lentes de contato de hidrogel de silicone incorporadas que compreendem um inserto da invenção nas mesmas.
