Patents by Inventor Marcia Ash

Marcia Ash has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Silicone hydrogels
    Publication number: 20070037898
    Abstract: The present invention provides silicone hydrogel materials having relatively high oxygen permeability and a relatively low modulus. The relatively-low modulus is achieved by adding a chain transfer agent into a polymerizable fluid composition in an amount sufficient to provide to the resultant silicone hydrogel material with a reduced modulus. In addition, the invention provides silicone hydrogel contact lenses comprising a silicone hydrogel material of the invention, a method for making a silicone hydrogel material of the invention, and a method for making a silicone hydrogel contact lens of the invention.
    Type: Application

  • Method for lathing silicone hydrogel lenses
    Publication number: 20060001184
    Abstract: 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.
