  • Patent number: 12004956
    Abstract: An acetabular reconstruction prosthesis with a piling-cup system is provided, which includes an iliac posterior pile screw, an iliac anterior pile screw, a pubic pile screw, an ischial pile screw, abutments, a 3D (three-dimensional) printed porous titanium mesh cup, locking screws, nuts, and tail cap screws. Four pile screws are the iliac posterior pile screw facing posterior of the ilium, the iliac anterior pile screw facing iliac tubercle, the ischial pile screw running along ischium ramus, and the pubic pile screw running along pubic ramus. A stable prothesis support system is formed in the acetabular reconstruction prosthesis with a piling-cup system, which conforms to the biomechanical characteristics of physiological pelvis, reduces the risk of prosthesis loosening and dislocation, and improves long-term stability of the prosthesis through biological fixation.

  • Patent number: 12004943
    Abstract: In some embodiments, a method for controlling an artificial iris may include receiving a measurement of light intensity detected by a sensor on or adjacent to the artificial iris. The method may include accessing a user-specific profile based on user calibration for determining one or more user-specific thresholds of light intensity of the user-specific profile. The one or more user-specific thresholds are associated with light intensities for triggering a change of light transmittance through the artificial iris. The method may include comparing the received measurement of light intensity to the one or more thresholds in the user-specific profile. The method may include determining, based on the comparing, whether to turn on or turn off one or more concentric rings of liquid crystals of the artificial iris for controlling an amount of light transmitted through the artificial iris.

  • Patent number: 11944535
    Abstract: A method and system provide an ophthalmic device. The ophthalmic device includes an ophthalmic lens having anterior surface, a posterior surface and at least one diffractive structure including a plurality of zones. The at least one diffractive structure is for at least one of the anterior surface and the posterior surface. Each zone includes at least one echelette having a least one step height. The step height(s) are individually optimized for each zone. To compensate chromatic aberration of eye from distance to a range of vision, a greater than 2? phase step height may be employed and the step height(s) folded by a phase, which is an integer multiple of two multiplied by ?. Hence chromatic aberration of eye may be compensated to improve vision from distance to near.
