    • Described herein are silicone fluids and silicone materials that posses high glass transition temperatures (T g s) when compared to conventional silicone materials. In one embodiment, an increased T g allows the formation of objects and materials by cryogenic lathing. The fluids and materials can be formed by curing silicone fluid with a cross-linker mixture comprising a cross-linker and a monofunctional hydride compound. Upon formation, the silicone materials can be extracted over long periods of time without loss of optical quality. The silicone materials can be sufficiently soft allowing folding and insertion through small incisions in the eye. Additionally, methods of forming optical silicone materials, lenses and silicone materials in general are also disclosed. In one embodiment, the method of forming a silicone based lens using cryogenic lathing techniques is described.
    • 这里描述的是与常规硅氧烷材料相比具有高玻璃化转变温度(Tg)的有机硅流体和硅氧烷材料。 在一个实施例中,增加的Tg允许通过低温车辙形成物体和材料。 流体和材料可以通过用包含交联剂和单官能氢化物化合物的交联剂混合物固化硅氧烷流体来形成。 在形成时,可以长时间地提取硅酮材料而不损失光学质量。 硅胶材料可以足够柔软,允许通过眼睛中的小切口进行折叠和插入。 此外,还公开了形成光学硅氧烷材料,透镜和硅酮材料的方法。 在一个实施例中,描述了使用低温车床技术形成硅氧烷基透镜的方法。
