    Abstract: A Light Adjustable Lens (LAL) comprises a central region, centered on a central axis, having a position-dependent central optical power, and a peripheral annulus, centered on an annulus axis and surrounding the central region, having a position-dependent peripheral optical power, wherein the central optical power is at least 0.5 diopters different from an average of the peripheral optical power, and the central axis is laterally shifted relative to the annulus axis. A method of adjusting the LAL comprises implanting a LAL; applying a first illumination to the LAL with a first illumination pattern to induce a position-dependent peripheral optical power in at least a peripheral annulus, centered on an annulus axis; determining a central region and a corresponding central axis of the LAL; and applying a second illumination to the LAL with a second illumination pattern to induce a position-dependent central optical power in the central region of the LAL.

  • Publication number: 20190142578
    Abstract: A graft for augmentation rhinoplasty, the graft including bone tissue and cartilage tissue, and a method of performing augmentation rhinoplasty by using the graft are disclosed. According to the disclosure, autologous tissue for augmentation rhinoplasty can be obtained in a sufficient amount to so that a nose can be uplifted to a desired height. In addition, rhinoplasy can be easily performed, resulting in a naturally-shaped nose. As the osseous tissue is grafted on the originally existing osseous tissue and cartilage tissue is grafted on the originally existing cartilage, the construction of the original anatomical structure of the nose can be allowed and there is an effect that there is no side effect such as a foreign body reaction.

    Abstract: A prosthetic vascular valve includes one or more continuous loops of frame material or one or more strands of material that do not form a continuous loop. The frame includes a plurality of longitudinal portions, wherein a membrane is attached to at least one of the longitudinal portions, and wherein the membrane is configured to open and close. During implantation, the frame engages the inner surface of the vein wall and is biased against the vein wall to remain stationary. In use, blood flows from an upstream end to a downstream end, wherein the membrane mitigates regurgitation of the blood as the blood is conveyed through the subject vein.

    Abstract: A foot assistive device for improving drop foot gait comprises an assistive device body and an elastic module. The assistive device body comprises a foot support base and a brace. The foot support base is movably connected to the brace. The elastic module connects the foot support base to the brace. The elastic module has a spring, a preset support included angle is formed between the foot support base and the brace under an elastic force of the spring. The support included angle is not larger than 90°. Thereby, when the foot is raised up, the foot support base is unlikely to drop excessively due to the foot weight, the drop foot gait is improved effectively.
