Abstract
Hydrogel polymers for use, for example, in contact lenses, drug delivery systems and/or stimulating devices. In some embodiments, the hydrogel formulations comprise diluent(s) to improve the dehydration characteristics and mechanical properties of a hydrogel polymer formulation compared to those without diluent(s). The diluent(s) include, for example, water and hydrophilic diluent(s) such as humectants.
Claims22
A composition comprising at least one hydrophilic monomer, at least one vinyl containing monomer, a siloxane cross-linker, and at least one diluent, wherein said at least one diluent comprises water and/or at least one humectant, wherein the siloxane crosslinker has a molecular weight from about 200 to about 6000 g/mol.
