Abstract:
The present invention relates to a method of manufacturing a contact lens including the steps of: (i) adding reactive components to a mold, wherein the reactive components comprise (a) at least one hydroxy-containing silicone component having a weight average molecular weight from about 200 to about 15,000 g/mole and (b) at least one mono-ether terminated, mono-methacrylate terminated polyethylene glycol having a weight average molecular weight from about 200 to about 10,000 g/mole; (ii) curing the reactive components within the mold to form the contact lens; and (iii) removing the contact lens from said mold.
