Patent number: 11143828Abstract: An optical switch incorporated in a photomedical system, and a method of treating tissue using the optical switch for creating pulsed light. A light source generates an optical beam. An aperture element includes a light-transmitting portion and a light-blocking portion. An optical element such as a mirror, prism or lens directs the optical beam to the aperture element, wherein the optical element is movable for translating the optical beam across the light-transmitting and light-blocking portions of the aperture element, or changing its angle of incidence through the aperture to produce one or more pulses of light from the optical beam. A lens focuses the one or more pulses of the optical beam onto target tissue. A controller controls the movement of the optical element to produce the one or more pulses of light.Type: GrantFiled: October 16, 2019Date of Patent: October 12, 2021Assignee: IRIDEX CorporationInventors: Michael W. Wiltberger, Dan E. Andersen, David H. Mordaunt

Patent number: 11026860Abstract: Optical scanning system and method for performing therapy on trabecular meshwork of a patient's eye, including a light source for producing alignment and therapeutic light, a scanning device for deflecting the alignment and therapeutic light to produce an alignment therapeutic patterns of the alignment and therapeutic light, and an ophthalmic lens assembly for placement over a patient's eye that includes a reflective optical element for reflecting the light patterns onto the trabecular meshwork of the patient's eye. The reflective optical element can be a continuous annular mirror (e.g. smooth or with multiple facets) to image the entire trabecular meshwork, or a reflective optical element that moves in coordination with the deflection of the beam. Visualization of the alignment and therapeutic patterns of light on the eye can be implemented by reflection thereof off a visualization mirror that transmits a portion of light emanating from the trabecular meshwork.Type: GrantFiled: June 28, 2005Date of Patent: June 8, 2021Assignee: IRIDEXInventors: Dan E. Andersen, David H. Mordaunt, Michael W. Wiltberger

Patent number: 10912677Abstract: A system and method for treating target tissue including a light source for generating a beam of light, a plurality of optical fibers, a deflection device configured to selectively deflect the light beam into the input ends of the optical fibers, one optical fiber input end at a time, and a probe having a tip with the output ends of the optical fibers and configured for insertion into target tissue. The probe tip is configured to sequentially project spaced apart spots of the light beam from the output ends as the deflection device deflects the light beam into the optical fibers. One or more moving or static deflecting optics at the probe tip can be used to statically or dynamically deflect the beam exiting the optical fibers.Type: GrantFiled: October 12, 2018Date of Patent: February 9, 2021Assignee: TOPCON MEDICAL LASER SYSTEMS INC.Inventors: David H. Mordaunt, Dan E. Andersen

Patent number: 10912678Abstract: A laser indirect ophthalmoscope (LIO) apparatus for photomedical treatment and/or diagnosis is presented. The LIO apparatus allows multiple spot ophthalmic surgery to be performed in a wider range of patient positions and less intrusively than currently available methods. The LIO apparatus utilizes a separate or integral beam multiplier that generates one or more optical beams via spatial and/or temporal separation, and an optical system that conditions and directs the one or more optical beams to a target to form a pattern. The LIO apparatus includes a headset, and is therefore wearable by the user (e.g., a physician).Type: GrantFiled: January 2, 2019Date of Patent: February 9, 2021Assignee: TOPCON MEDICAL LASER SYSTEMS INC.Inventors: Dan E. Andersen, David H. Mordaunt

Patent number: 10874553Abstract: System and method for making incisions in eye tissue at different depths. The system and method focuses light, possibly in a pattern, at various focal points which are at various depths within the eye tissue. A segmented lens can be used to create multiple focal points simultaneously. Optimal incisions can be achieved by sequentially or simultaneously focusing lights at different depths, creating an expanded column of plasma, and creating a beam with an elongated waist.Type: GrantFiled: June 1, 2017Date of Patent: December 29, 2020Assignee: AMO Development, LLCInventors: Daniel V. Palanker, Mark S. Blumenkranz, David H. Mordaunt, Dan E. Andersen

Publication number: 20200155352Abstract: Laser assisted cataract surgery methods and devices utilize one or more treatment laser beams to create a shaped opening in the anterior lens capsule of the eye when performing a capsulorrhexis procedure. A light absorbing agent may be applied to the anterior lens capsule to facilitate laser thermal separation of tissue along a treatment beam path on the lens capsule. Relative or absolute reflectance from the eye, and optionally from a surgical contact lens, may be measured to confirm and optionally quantify the presence of the light absorbing agent, before the treatment beam is applied.Type: ApplicationFiled: January 21, 2020Publication date: May 21, 2020Inventor: David H.
