| description | The present invention provides methods for lathing at room temperature a silicone hydrogel material, in particular silicone hydrogel material having a high oxygen permeability and made of a polymerizable composition containing a relative large amount of oxyperm component, into contact lenses.
L'invention concerne des procédés de tournage à la température ambiante d'un matériau hydrogel de silicone, notamment de matériau hydrogel possédant une perméabilité à l'oxygène élevée et formé d'une composition polymérisable contenant une quantité relativement importante de composant =, de manière que des lentilles de contact soient formées. |
