Zusammenfassung:An ophthalmic device is disclosed which is a polymerization product of a monomeric mixture comprising: (a) a major amount of one or more first non-silicone- containing hydrophilic monomers; (b) one or more hydrophobic monomers; and (c) a crosslinking agent mixture comprising (i) one or more di-, tri-or tetra(meth)acrylate- containing crosslinking agents and (ii) one or more di-, tri-or tetracarbamate-containing crosslinking agents, wherein the ophthalmic device has an equilibrium water content of at least about 65 weight percent.
