  • Patent number: 10130733
    Abstract: The invention is directed to a method of cleaning and disinfecting a contact lens. The method includes instructing a consumer to disinfect their contact lens comprising the following steps: remove a contact from an eye and position the lens in a lens assembly that includes a cap member; add a disinfection solution to the lens case such that the lens is submerged in the solution upon closure of the lens case with the cap member. The disinfection solution will comprise 0.5 wt. % to 6 wt. % hydrogen peroxide or a chemical precursor of hydrogen peroxide, and a P-metal modulating compound. The presence of the P-metal modulating compound in the disinfection solution decreases the neutralization rate of the hydrogen peroxide. The disinfection system exhibits a pseudo first-order, half-life of hydrogen peroxide from 12 minutes to 30 minutes over an initial sixty minutes of neutralization following exposure of the disinfection solution to a catalyst comprising a P-metal.

  • Patent number: 10076445
    Abstract: A system and method are provided for removing a natural lens and inserting an Intraocular Lens (IOL) into the lens capsule of an eye. Specifically, this is accomplished by inserting the IOL through an opening on the posterior capsule that is created using a focused laser beam. The system includes a laser unit, a detector for creating images of the interior of the eye, and a computer that controls the cooperative functions of the detector and the laser unit. Based on images of the posterior capsule provided by the detector, the computer is used to control movements of the focal point through tissue of the posterior capsule to perform Laser Induced Optical Breakdown (LIOB) on posterior capsule tissue. The result is a laser capsulotomy that creates an opening through the posterior capsule allowing the natural lens to be removed and the IOL to be implanted.

  • Patent number: 9974692
    Abstract: A system and method for performing a femto-fragmentation procedure on tissue in the crystalline lens of an eye requires that a laser beam be directed and focused to a focal point in the crystalline lens of the eye. The focal point is then guided, relative to an axis defined by the eye, to create a segment cluster by causing Laser Induced Optical Breakdown (LIOB) of tissue in the crystalline lens. The resultant segment cluster includes a plurality of contiguous, elongated segments in the crystalline lens that are individually tapered from an anterior end-area to a posterior end-area. Specifically, this is done to facilitate the removal of individual segments from the segment cluster in the crystalline lens.
