Patent number: 11833078Abstract: A multi-spot ophthalmic laser device that produces spatially distributed laser spots with the spatial distribution of the laser spots defined by a spot diameter to space ratio in the range 1:2 to 1:20. The multi-spot ophthalmic laser device comprises: a laser module producing a laser pulse or sequence of laser pulses each having: a pulse duration in the range of 10 ps to 20 ?s; a wavelength in the range 500 nm to 900 nm; and a pulse energy in the range 10 ?J to 10 mJ per pulse; and an optical beam profiling module that modifies an output beam profile of each pulse of the laser module to deliver multiple spatially distributed laser spots of defined size and energy. The multi-spot ophthalmic laser device is used in a method of improving the function of the retina of a human eye by irradiation through the cornea of the eye to the retinal pigmented epithelium by a treatment laser having a beam profile with spatially distributed energy peaks.Type: GrantFiled: August 17, 2018Date of Patent: December 5, 2023Assignee: ELLEX MEDICAL PTY LTDInventors: Wei Xia, Victor Previn, Robin McWilliams, John Marshall

Patent number: 11147624Abstract: The invention resides in a pattern laser comprising a plurality of laser devices each emitting a treatment laser beam into an optical fibre of an optical fibre bundle. An optical coupling module is associated with each laser device and each optical fibre for coupling a treatment laser beam into the associated optical fibre. A controller controls the operation of the laser devices by selectively turning on or off one or more of the laser devices so as to form a laser treatment pattern at an end of the fibre bundle away from the laser devices. A delivery system images the output from the fibre bundle to a treatment zone.Type: GrantFiled: December 14, 2016Date of Patent: October 19, 2021Assignee: ELLEX MEDICAL PTY LTDInventors: Wei Xia, Eric Benson, Yong Min Ooi, Victor Previn, Timothy Dixon

Patent number: 9468775Abstract: 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.Type: GrantFiled: December 15, 2014Date of Patent: October 18, 2016Assignee: ELLEX MEDICAL PTY LTDInventor: Malcolm Plunkett
