Patent number: 10369051Abstract: 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.Type: GrantFiled: May 23, 2013Date of Patent: August 6, 2019Assignee: ELLEX R&D PTY LTDInventors: Malcolm Plunkett, Wei Xia

Patent number: 8562595Abstract: 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.Type: GrantFiled: October 25, 2007Date of Patent: October 22, 2013Assignee: Ellex R&D Pty LtdInventors: Malcolm Plunkett, Aly Hussain, John Marshall

Patent number: 8496649Abstract: A laser treatment device for use in retinal regeneration. The laser treatment device includes a laser module that delivers a pulse or sequence of pulses having a pulse duration in the range of 50 ps to 500 ns, a wavelength in the range 500 nm to 900 nm, and a pulse energy in the range 100 ?J to 10 mJ. The laser treatment device also includes a uniform irradiance module that modifies an output beam profile of the laser module to produce a uniform treatment effect and a beam delivery and viewing module that delivers the laser pulse or pulses to the retina with a radiant exposure in the range of 8 mJ/cm2 to 8000 mJ/cm2 per pulse.Type: GrantFiled: May 29, 2008Date of Patent: July 30, 2013Assignee: Ellex R&D Pty LtdInventors: Victor Previn, Malcolm Plunkett
