    • An accommodating intraocular lens system including a higher diopter positive intraocular lens and a lower diopter negative intraocular lens. The positive intraocular lens includes a positive optic portion having an outer peripheral edge and two or more haptic elements. The negative intraocular lens includes a negative optic portion having an outer peripheral edge and two or more haptic elements. Each haptic element is formed to have specific flexibility characteristics so as to be less resistant to bending in a plane generally parallel to an eye's optical axis than in a plane generally perpendicular to the eye's optical axis. The accommodating intraocular lens system is so designed with specific flexibility characteristics to facilitate axial displacement of the positive optic portion with respect to the negative optic portion along the eye's optical axis under a compression force. Through the axial displacement of the positive optic portion with respect to the negative optic portion, accommodative effects are maximized to achieve multi-distance visual imaging.
    • 包括较高屈光度正性人工晶状体和较低屈光度负性人工晶状体的适应性眼内透镜系统。 正面人工晶状体包括具有外周边缘和两个或更多个触觉元件的正光学部分。 负的人工晶状体包括具有外周边缘和两个或更多个触觉元件的负光学部分。 每个触觉元件形成为具有特定的柔性特性,以便在大致平行于眼睛的光轴的平面中比在大致垂直于眼睛的光轴的平面中的抗弯曲性更差。 容纳眼内透镜系统被设计成具有特定的柔性特性,以促进正光学部分在压缩力下沿着眼睛的光轴相对于负光学部分的轴向位移。 通过正光学部分相对于负光学部分的轴向位移,最大化调节效应以实现多距离视觉成像。

    • An accommodating intraocular lens including a higher diopter positive intraocular lens and a lower diopter negative intraocular lens. The positive intraocular lens includes a positive optic portion having an outer peripheral edge and two or more polyurethane elastomer flexible attachment components. The negative intraocular lens includes a negative optic portion having an outer peripheral edge and two or more polyurethane elastomer flexible attachment components. Each flexible attachement component is durable and formed to have specific flexibility characteristics so as to be less resistant to bending in a plane generally parallel to an eye's optical axis than in a plane generally perpendicular to the eye's optical axis. The subject durable accommodating intraocular lens enables axial displacement of the positive optic portion with respect to the negative optic portion along the eye's optical axis under a compression force. The flexible attachment components are durable to allow dependable flexation thereof millions of times during a patient's lifetime. Through this flexation of the flexible attachment components and axial displacement of the positive optic portion with respect to the negative optic portion, accommodative effects are maximized to achieve multi-distance visual imaging.

    • The invention discloses a novel process for producing covalently bonded laminated structures composed of polyurethane elastomer and vulcanized rubber layers. As the joining means for covalently bonding the polyurethane elastomer and vulcanizable rubber laminates the process utilizes novel grafted polyurethane joining compositions comprised of polyurethane elastomer, a polyisocyanate, and a hydroxyl containing polybutadiene difunctional linker molecule. In practicing the process of the invention, the grafted polyurethane joining composition is first prepared by means that create covalent chemical bonds between the polyurethane elastomer and a first functional (NCO) group on the polyisocyanate, as well as between a hydroxyl on the polybutadiene difunctional linker molecule and a second functional (NCO) group on the polyisocyanate. This novel grafted polyurethane composition is then used to bond layers of polyurethane elastomer to layers of vulcanizable rubber. In constructing a laminated product, the grafted polyurethane joining composition is interposed between the polyurethane elastomer and vulcanizable rubber layers. The resulting assembly is then heated at a temperature sufficient to allow formation of covalent bonds.
    • 本发明公开了一种由聚氨酯弹性体和硫化橡胶层组成的共价键合叠层结构的新方法。 作为用于共价键合聚氨酯弹性体和可硫化橡胶层压体的接合方法,该方法利用由聚氨酯弹性体,多异氰酸酯和含羟基的聚丁二烯双官能连接分子组成的新型接枝聚氨酯接合组合物。 在实施本发明的方法中,接枝聚氨酯接合组合物首先通过在多异氰酸酯之间和聚丁二烯双官能接头之间的羟基之间产生聚氨酯弹性体与第一官能(NCO)基团之间的共价化学键, 分子和多异氰酸酯上的第二官能(NCO)基团。 然后使用该新型接枝聚氨酯组合物将聚氨酯弹性体层粘合到可硫化橡胶层上。 在构造层压制品时,接枝聚氨酯接合组合物介于聚氨酯弹性体和可硫化橡胶层之间。 然后将所得组件在足以形成共价键的温度下加热。
