General silicon hydrogel lenses made of siloxane-based polymers have a hydrophilic surface layer to promote wearability. However, the water content of the layer is not high enough to prevent dry eye symptoms such as irritated, scratchy and red eyes when wearing them for a long time. In this study, silicon hydrogel lenses were exposed to O2 plasma to form hydroxyl groups, and then reacted with cellulose to create crosslinked cellulose layers on the surfaces of the lenses. The thickness of the surface layer was controlled by reaction time and concentration of reactants. |
