Abstract

lentes de contato de silicone hidrogel com níveis aceitáveis de perda de energia as lentes de contato de silicone hidrogel com níveis oftalmologicamente aceitáveis de perda de energia são descritas. as lentes são obtidas a partir de uma composição polimerizável, incluindo um primeiro monômero siloxano representado pela fórmula geral (1): onde m da fórmula (1) representa um número inteiro de 3 a 10, n da fórmula (1) representa um número inteiro de 1 a 10, r^ 1^ da fórmula (1) é um grupo alquil tendo de 1 a 4 átomos de carbono, e cada r^ 2^ da fórmula (1) é, independentemente, tanto um átomo de hidrogênio ou um grupo metil; as lentes também incluem unidades derivadas de um segundo monômero de siloxano que é um polidimetilsiloxano capeado (end-capped) com metacrilato em duas terminações com um peso molecular médio de pelo menos 7.000 daltons. a perda de energia média das lentes de contato de silicone hidrogel é de cercada de 30% a cerca de 45%, quando as lentes são completamente hidratadas. os lotes de lentes de contato de silicone hidrogel e os métodos de fabricação das lentes de contato de silicone hidrogel são também descritos.
