Abstract

MOLDAGENS BIOMéDICAS. A presente Invenção refere-se a uma moldagem biomédica que é obtenível ao reticular em um molde uma solução aquosa de um pré-polímero de álcool de polivinila reticulável (PVA) que compreende pelo menos 0,5% em peso, baseado na formulação total, de um PVA não-reativo, onde o peso molecular médio numérico do PVA não-reativo é maior do que aquele do PVA retículável De acordo com a invenção as moldagens tais como lentes de contato são proporcionadas com um conforto ao usuário aperfeiçoado.
