In earlier times, a lot of people using contact lens had experienced its serious side effects. Therefore, contact lens industry have been constantly developing an improved raw materials to reduce side effects of contact lenses. Most of the side effects of rigid contact lenses have been found to be due to the low oxygen permeability of the lens, but by replacing it with a raw material having high oxygen permeability, the side effects of the contact lens can be reduced. For this reason, silicone based raw materials are important in lens market because it is known that silicon-oxygen bonds (silicones) increase oxygen permeability. However, one problem remains, the more silicone fraction increase, the more hydrophobicity becomes. The hydrophobicity of silicone can be resolved by adding a hydrophilic functional group which increase hydrophilicity and wettability to silicone based polymers. Accordingly, silicone monomers and silicone macromers for silicone hydrogels require a hydrophilic group as well as a light curable functionality for final curing. We have studied how to optimize synthetic pathways for representative silicone compounds for silicone hydrogels.
