Hydrophilic or hydrogel materials produced by Contamac offer a range of water contents between 38% and 75%. GM Advance is provided in 49% and 58% water contents, both featuring lower modulus figures and therefore offering greater flexibility when machined to a finished soft contact lens. GM Advance resists dehydration longer and rehydrates faster than many other products that are currently available. Other well known Contamac products include FDA approved 55% Methafilcon. Flexibility, stability and manufacturability; all hallmarks of Contamac's hydrogel materials
