  • Publication number: 20170020661
    Abstract: Embodiments disclosed herein are directed to intraocular lens systems includes at least one intraocular lens device and methods of using the same. The at least one intraocular lens device includes one or more photodetectors and an intraocular lens exhibiting a modifiable focal length. The one or more photodetectors are configured to detect light that is used to determine a presence of the object or the apparent object distance. The focal length of the intraocular lens can be modified depending on the determined presence of the object or the apparent object distance.

  • Publication number: 20170020659
    Abstract: Embodiments disclosed herein are directed to intraocular lens systems having a plurality of materials therein, with at least some of the materials having a diffraction pattern therein and an electrically-modifiable index of refraction collectively configured to selectively alter the focal length of the intraocular lens system. Methods of modifying a focal length of an intraocular lens system are also disclosed.

  • Publication number: 20160095699
    Abstract: An improved posterior chamber phakic intraocular lens (PCP-IOL) having a haptic with a collar, self-adjusting struts, and lens is disclosed. Haptic or lens of the PCP-IOL may include a protected orifice. A disclosed PCP-IOL may be configured to fit anatomy of varying sizes, and may be self-centering; additionally, a PCP-IOL as set forth herein may allow peripheral aqueous flow between anterior and posterior chambers of a patient's eye.

  • Publication number: 20140094908
    Abstract: Novel intraocular lenses comprising at least one haptic having a shape memory alloy with a transition temperature substantially higher than the human body temperature, the shape memory alloy being post-surgically, selectively adjustable with a laser beam.

  • Publication number: 20130018276
    Abstract: Provided herein is a measurement tool for implantable non-spherical asymmetric optics comprising a viewable, rotatable angular caliper superimposable over an image of an eye. Also provided are methods for optimally placing non-spherical asymmetric optics in an eye of a patient and for correcting post-operative astigmatism in a patient having cataract surgery. The measurement tool is useful to plan the optimal correct surgical placement of a non-spherical asymmetric optic, e.g., a toric intraocular implant or a toric intraocular contact lens, in the eye. By superimposing the measurement tool over a corneal topographic image, an optimal positioning of the non-spherical asymmetric optic can be effected in an optical zone of interest. Correct placement or re-placement at least minimizes astigmatism in post-operative vision.
