  • Patent number: 10308835
    Abstract: The invention is related to a cost-effective method for making a silicone hydrogel contact lens having a crosslinked hydrophilic coating thereon. A method of the invention involves heating a silicone hydrogel contact lens in an aqueous solution in the presence of a water-soluble, highly branched, thermally-crosslinkable hydrophilic polymeric material having positively-charged azetidinium groups, to and at a temperature from about 40° C. to about 140° C. for a period of time sufficient to covalently attach the thermally-crosslinkable hydrophilic polymeric material onto the surface of the silicone hydrogel contact lens through covalent linkages each formed between one azetidinium group and one of the reactive functional groups on and/or near the surface of the silicone hydrogel contact lens, thereby forming a crosslinked hydrophilic coating on the silicone hydrogel contact lens. Such method can be advantageously implemented directly in a sealed lens package during autoclave.

  • Patent number: 10258229
    Abstract: In a method for the acquisition of optical coherence tomography image data of retina tissue of an eye (99) of a human subject using an acquisition device comprising an imaging optics (2), a first image associated with a baseline relative positioning of the eye (99) of the human subject with respect to the imaging optics (2) is acquired at a first point in time. The baseline relative positioning is stored. At a second point in time being different from the first point in time, the baseline relative positioning of the same eye (99) of the same human subject with respect to the imaging optics (2) is re-established and a second image is acquired. For re-establishing the positioning, a present relative positioning of the eye (99) of the human subject with respect to the imaging optics is determined based on a video image of an iris region of the eye.

  • Patent number: 10204451
    Abstract: A multi-optical surface optical design for generating multiple focal planes with identical image data displayed at substantially the same time to generate the perception of varying focal depths is described. The multi-optical surface optical design can include a device comprising reflective optical surfaces that can be arranged on top of one another and configured to generate multiple focal planes and an image source for projecting image data onto the reflective optical surfaces. The technologies described can cause image data to be rendered in a focal plane corresponding to a desired focal distance and multiple copies of the image can be perceived in other focal planes of the multiple focal planes at substantially the same time as the image data is rendered in the focal plane. Each copy of the multiple copies can be presented with a perceived degree of sharpness such that each copy is out-of-focus.
