摘要:
The present invention relates to wettable silicone hydrogels comprising the reaction product of at least one siloxane containing component and at least one reactive, hydrophilic polymeric internal wetting agent. The present invention further relates to silicone hydrogel contact lenses comprising at least one oxygen permeable component, and an amount of reactive, hydrophilic polymeric internal wetting agent sufficient to impart wettability to said device.
摘要:
Disclosed are low-tack, hydrophobic, high refractive index, acrylic materials. These materials, especially useful as intraocular lens materials, contain one or more aryl acrylic hydrophobic monomers as principal device-forming monomers, a tack-reducing block copolymer additive and a glistening-reducing additive. In addition to their use as intraocular lens materials, the present materials are also suitable for use in other implantable ophthalmic devices.
摘要:
Lactam polymers has been modified with sodium borohydride (NaBH4) to yield lactam polymers bearing hydroxyl functional groups. These functional groups are useful for the covalent attachment of reactive groups, fluorescent probes, antimicrobial agents, bioactive factors, and drugs. The resulting as components for medical devices, specifically ophthalmic devices and more specifically contact lenses. Hydrogels based on these polymers are also useful for biomedical applications in the areas of drug delivery, tissue engineering, and implantable devices.
