  • Patent number: 11793908
    Abstract: A bioanalogic implantable ophthalmic lens (“BIOL”) capable of replacing the natural crystalline lens (NCL) in its various essential functions after the NCL having been removed and BIOL implanted into the posterior eye chamber and placed into the capsular bag vacated from the NCL. At least the posterior surface of the lens has a convex shape and is made from a transparent flexible hydrogel material. At least the anterior and posterior optical surfaces are defined by rotation of one or more conic sections along the main optical axis and the surfaces defined by the rotation will include a plane perpendicular to the axis and conical surface symmetrical by the axis. A hydrogel implantable ophthalmic lens whose optical parameters can be optimized and/or customized by a controlled absorption of electromagnetic radiation resulting in a change of the refractive index of the irradiated hydrogel.

  • Publication number: 20230293865
    Abstract: A cervical dilator including a stem comprising a partly or fully dehydrated hydrogel comprising a water-insoluble synthetic hydrophilic polymer capable of radial expansion due to absorption of water from a bodily fluid. The cervical dilator softens and ripens the cervical tissue and expands the cervical canal by a combined action of radial hydrogel stem expansion and osmotic withdrawal of water from the tissue. The osmotic withdrawal is caused by at least one osmotically active compound, such as a water-soluble salt, a polyelectrolyte, or a mixture thereof, wherein the at least one osmotically active compound is dispersed in the hydrogel. The cervical dilator may also include a non-toxic plasticizer of the hydrogel, such as water.
