  • Patent number: 7001377
    Abstract: An eye-tracking method includes the step of removably affixing a ring member to an eye in surrounding relation to a cornea of the eye. A plurality of incident light spots are transmitted onto the ring member, and reflections are detected from the ring member of the incident light spots. By analyzing the reflections, eye movement can be determined. A system for tracking eye movement includes a ring member and a device for removably affixing the ring member to an eye in surrounding relation to a cornea of the eye, such as, for example, by applying a vacuum to the ring. A light transmitter transmits a plurality of incident light spots onto the ring member, and a detector for detecting reflections from the ring member of the incident light spots. A processor and software installed thereon are adapted to perform calculations to determine eye movement from an analysis of the reflections.

  • Patent number: 6998489
    Abstract: Methods of making indazoles are described. The methods involved reacting an aromatic aldehyde with a nitrogen source to form a nitroso aromatic aldehyde. The nitroso aromatic aldehyde is reacted with a reducing agent to form an indazole which ultimately can be used to form desired indazoles which are preferably pharmaceutically active products. The process of the present invention further permits the formation of enantiomerically enriched or pure indazoles such as aminoalkyl indazoles.

  • Patent number: 6972034
    Abstract: A two part lens system. The first part is a ring-like supporting component that is implanted in the capsular bag following cataract surgery. The first component is a non-optical component and contains a pair of haptics for fixating the first component within the capsular bag. The second component is an optical component that contains all of the corrective optical power of the lens system. The second component has a pair of tabs for locking the second component within the first component.

  • Patent number: 6969032
    Abstract: Apparatus and methods for use in ophthalmic surgery in which a container for fluid is connected to a line through which fluid flows to a surgical handpiece for the irrigation of a patient's eye are provided. A sensor emits a magnetic field and a detector causes another magnetic field to be generated. The interaction of the two magnetic fields causes a pulse to be generated. Based on the timing of the generated pulse, the apparatus or method determines the absolute position of the support coupled to the container and adjusts the height of the support. Circuitry is also provided to prevent changes in height of the support by preventing supply of drive currents and by applying a hold current or by generating an electro motive force.

  • Patent number: 6969403
    Abstract: A two-optic accommodative lens system. The first lens has a negative power and is located posteriorly against the posterior capsule. The periphery of the first optic contains a pair of clasps. The second optic is located anteriorly to the first optic and is of a positive power. The peripheral edge of the second optic contains a pair of locking arms that fit into the clasps contained on the periphery of the first optic to lock the second optic onto the first optic, but allow for rotation of the arms within the clasps. Hinge structures on the locking arms allow the second optic to move relative to the first optic along the optical axis of the lens system in reaction to movement of the ciliary muscle.
