摘要:
Disclosed in this specification is a method for forming a silicone hydrogel material that is useful for forming contact lens materials. The method includes using an effective amount of a borate additive to reduce the gel time of the silicone hydrogel reactive mixture and/or enhance the optical properties of the resulting cured material.
摘要:
This invention includes a wettable biomedical device containing a high molecular weight hydrophilic polymer and a hydroxyl-functionalized silicone-containing monomer. This invention includes a wettable silicone hydrogel comprising the reaction product of a least one silixanc containing macromer; at least one high molecular weight hydrophilic polymer; and at least one comptabilizing component as well as contact lens, medical devices and methods of obtaining such products.
摘要:
The present invention is a composition, which may be used to form a clear article, such as a contact lens, comprising a silicone containing component, a hydrophilic component, a high molecular weight hydrophilic polymer and a diluent having an alpha value of between about 0.05 to about 1 and a Hansen solubility parameter of less than about 10.
摘要:
An optically clear antimicrobial lens, containing greater than 0.01 weight percent activated silver is disclosed as well as methods for the production, use, and storage of the lens.
