  • Publication number: 20210251744
    Abstract: A composite light adjustable intraocular lens comprises an acrylic diffractive intraocular lens, having a diffractive structure and haptics; and a silicone light adjustable lens, attached to the acrylic diffractive intraocular lens. The diffractive structure produces constructive interference in at least four consecutive diffractive orders corresponding a range of vision between near and distance vision, wherein the constructive interference produces a near focal point, a distance focal point corresponding to the base power of the ophthalmic lens, and an intermediate focal point between the near focal point and the distance focal point and wherein a diffraction efficiency of at least one of the diffractive orders is suppressed to less than ten percent.

  • Patent number: 10966819
    Abstract: A composite light adjustable intraocular lens, can include an intraocular lens (IOL), a light adjustable lens, attached to the intraocular lens, and haptics. In some cases, a composite light adjustable intraocular lens can include an intraocular lens, and haptics, attached to the IOL with light-adjustable hinges. A method of adjusting an implanted composite light adjustable intraocular lens can include planning a targeted optical outcome of an implantation of the composite light adjustable intraocular lens into an eye; implanting, the composite light adjustable intraocular lens into the eye; performing a diagnostic measurement to evaluate an implanted optical outcome of the implantation; determining a correction based on a comparison of the planned optical outcome and the implanted optical outcome; and applying a stimulus to adjust an optical characteristic of the composite light adjustable intraocular lens to induce the determined correction.

  • Patent number: 10603216
    Abstract: Apparatus and methods of treating a hard lens region of an eye with a laser where one method includes identifying a boundary of the hard lens region, selecting a laser-parameter to enable a photo disruptive procedure in the hard lens region and to control a spreading of bubbles in the hard lens region, modifying a mechanical property of a posterior portion of the hard lens region in a proximity of the identified boundary by the photo disruptive procedure, and modifying a mechanical property of a portion anterior to the modified posterior portion of the hard lens region by the photo disruptive procedure. The laser bubbles can be applied to form incisions which are non-transverse to an axis of the eye and intersect the lens fibers.

  • Patent number: 10292866
    Abstract: A method of transplanting a cornea from a donor to a recipient is disclosed. An undercut is incised within stromal tissue of the donor cornea. Following formation of the undercut, the donor cornea is grafted onto a recipient. The undercut may be formed before or after the cornea is removed from the donor, and is preferably formed by photoaltering the stromal tissue using a laser. A sidecut may also be incised in the donor cornea, thereby forming a corneal flap, prior to grafting. In addition, a corneal section may be excised from the donor cornea using a trephine, a laser, or other appropriate surgical equipment.
