Abstract
This invention includes a wettable biomedical device containing a high molecular weight hydrophilic polymer and a hydroxyl-functionalized silicone-containing monomer.
Claims12
An ophthalmic device comprising at least one hydroxyl-functionalized silicone-containing monomer and an amount of high molecular weight hydrophilic polymer sufficient to provide said device, without a surface treatment, with an advancing dynamic contact angle of less than about 80°.
An ophthalmic device comprising at least one hydroxyl-functionalized silicone-containing monomer and an amount of high molecular weight hydrophilic polymer sufficient to provide said device, without a surface treatment, with an advancing dynamic contact angle which is at least about 10% lower than an advancing dynamic contact angle for an ophthalmic device which does not contain said hydrophilic polymer.
An ophthalmic device comprising at least one hydroxyl-functionalized silicone-containing monomer and an amount of high molecular weight hydrophilic polymer sufficient to provide said device, without a surface treatment, with tear film break up time after about one day of wear of at least about 7 seconds.
