摘要:
An ophthalmic device is disclosed that is a polymerization product of a monomeric mixture comprising (a) a major amount of a non-silicone-containing hydrophilic monomer; (b) a hydrophobic monomer; and (c) a crosslinking agent, wherein the ophthalmic device has an equilibrium water content of at least about 70 weight percent and further wherein the ophthalmic device has an evaporative dehydration barrier layer on the surface thereof. A method for the mitigation of evaporative corneal dehydration employing the high water content ophthalmic device is also disclosed.
