Abstract
The present invention provides a silicone hydrogel composition. The silicone hydrogel composition includes a water-soluble silicone macromere, a hydrophilic monomer, a crosslinker, an initiator and an organic solvent. The water-soluble silicone macromere, the hydrophilic monomer, the crosslinker and the initiator is respectively in the amount of 50-80 wt %, 19-50 wt %, 0.1-1.5 wt % and 0.1-1 wt % based on the total weight of the silicone hydrogel composition.
