METHOD OF MAKING OCULAR DEVICES
A method of decreasing the amount of cosmetic defects in contact lenses made from hydrophilic and hydrophobic monomers. By filtering the monomer mixture with a filter, the hydrophilic and hydrophobic components are finely dispersed throughout the mixture. Dissolved gases contained within the mixture...

| description | A method of decreasing the amount of cosmetic defects in contact lenses made from hydrophilic and hydrophobic monomers. By filtering the monomer mixture with a filter, the hydrophilic and hydrophobic components are finely dispersed throughout the mixture. Dissolved gases contained within the mixture are also finely dispersed. Contact lenses produced from this method have improved optical quality.
La présente invention concerne un procédé de réduction des défauts de fabrication apparents dans des lentilles de contact à base de monomères hydrophiles et hydrophobes. En filtrant le mélange de monomères avec un filtre, les composants hydrophiles et hydrophobes sont finement dispersés dans le mélange. Les gaz dissous contenus dans le mélange sont également finement dispersés. En l'occurrence, les lentilles de contact produit selon ce procédé présentent une qualité optique supérieure. |
