    • Methods and devices for altering the power of a lens, such as an intraocular lens, are disclosed. In one method, the lens comprises a single polymer matrix containing crosslinkable pendant groups, wherein the polymer matrix increases in volume when crosslinked. The lens does not contain free monomer. Upon exposure to ultraviolet radiation, crosslinking causes the exposed portion of the lens to increase in volume, causing an increase in the refractive index. In another method, the lens comprises a polymer matrix containing photobleachable chromophores. Upon exposure to ultraviolet radiation, photobleaching causes a decrease in refractive index in the exposed portion without any change in lens thickness. These methods avoid the need to wait for diffusion to occur to change the lens shape and avoid the need for a second exposure to radiation to lock in the changes to the lens.
    • 公开了用于改变诸如人工晶状体的透镜的功率的方法和装置。 在一种方法中,透镜包含含有可交联侧基的单一聚合物基质,其中当交联时聚合物基体的体积增加。 镜头不含有游离单体。 当暴露于紫外线辐射时,交联使得透镜的暴露部分体积增加,导致折射率增加。 在另一种方法中,透镜包含含有可光漂白的发色团的聚合物基质。 在紫外线照射下,光漂白导致曝光部分的折射率降低,透镜厚度没有变化。 这些方法避免了等待发生扩散以改变透镜形状的需要,并且避免了第二次暴露于辐射以锁定透镜变化的需要。

    • A multi-layer driver plate is disclosed for use in electromagnetic sheet metal forming operations. In one embodiment, the driver plate comprises a first layer characterized by low electrical resistivity and thickness for inducement and application of a suitable electromagnetic forming force, a second layer comprising an elastomeric material for compressing a sheet metal workpiece against a die surface and then regaining its original pre-forming structure, and a third layer interposed between the first layer and the second layer to protect the EMF force providing layer and to provide overall strength and durability to the EMF driver plate.
    • 公开了用于电磁钣金成型操作的多层驱动器板。 在一个实施例中,驱动器板包括第一层,其特征在于用于诱导和施加合适的电磁成形力的低电阻率和厚度,第二层包括用于将金属板工件压靠在模具表面上的弹性材料,然后重新获得 原始预成形结构,以及插入在第一层和第二层之间的第三层,以保护EMF力提供层并为EMF驱动器板提供总体强度和耐久性。
