Modern lenses have been developed that are made of softer materials, typically hydrogels and particularly silicone hydrogels. Silicone hydrogels are water-swollen polymer networks that have high oxygen permeability and surfaces that are more hydrophobic than hydrophilic. These lenses provide a good level of comfort to many lens wearers, but there are some users who experience discomfort and excessive ocular deposits leading to reduced visual acuity when using these lenses. This discomfort and deposits has been attributed to the hydrophobic character of the surfaces of lenses and the interaction of those surfaces with the protein, lipids and mucin and the hydrophilic surface of the eye.Others have tried to alleviate this problem by coating the surface of silicone hydrogel contact lenses with hydrophilic coatings, such as plasma coatings Uncoated lenses having low incidences of surface deposits are not disclosed.Incorporating internal hydrophilic agents (or wetting agents) into a macromer containing reaction mixture has ...
