  • Patent number: 10898378
    Abstract: A mirror for an ophthalmic laser treatment device that is movable on an axis from a position in a treatment laser beam path to a position out of the treatment laser beam path. The mirror reflects light from a light source into the eye of a patient. The mirror is biased towards a position in the path and is moved out of the path by an actuator just long enough for the laser treatment to be applied and without noticeable interruption to viewing by a user.

  • Patent number: 9468775
    Abstract: A method of immunotherapy of a mammal or a laser device therefor, includes the step of treating one or more immune privileged cells, tissue or organs of said mammal with a laser to reduce or eliminate the immune privilege status of said one or more cells, tissues and/or organs to thereby elicit an immune response that is beneficial to the mammal. The method of immunotherapy avoids or minimizes lasting damage to the treated cells, tissues and/or organs. The laser treatment is typically, although not exclusively to the pigmented epithelium of the eye or eyes. The method may be for treating a disease or conditions selected from a bacterial infection, a viral infection, early AMD, glaucoma, diabetic retinopathy, multiple sclerosis, Parkinson's disease, and Alzheimer's disease. Typically, the radiant exposure level of the laser treatment is no greater than 60-100% of a visible effect threshold.

  • Patent number: 8562595
    Abstract: A method of retinal regeneration which improves retinal function by reversal of the degradation of the transport properties of Bruch's membrane. The method involves irradiation through the cornea of the eye to the retinal pigmented epithelium by a laser pulse or sequence of laser pulses having a pulse duration in the range of 10 ps to 20 ?s and at a wavelength in the range of about 500 nm to 900 nm. The method applies a radiant exposure which results in the damaging or altering of the retinal pigmented epithelium cells in such a manner as to trigger cellular responses which improve the hydraulic conductivity of Bruch's membrane without causing irreversible damage to adjacent retinal structures and layers.

  • Publication number: 20070213693
    Abstract: An ophthalmic laser system which produces controlled bursts of laser pulses and incorporates a system control processor that calculates the likely tissue effects and the total treatment time based on selected laser treatment parameters. The system incorporates a graphical user interface that displays the likely tissue effects to the user (ophthalmic surgeon) to assist with selection of optimal treatment parameters. The system and method of operation is particularly useful for procedures such as selective retinal therapy by displaying a therapeutic window in which treatment of target tissue is achieved without damage to surrounding tissue.
