Patent number: 10098781Abstract: 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: March 22, 2007Date of Patent: October 16, 2018Assignee: TOPCON MEDICAL LASER SYSTEMS INC.Inventors: David H. Mordaunt, Dan E. Andersen

Patent number: 10045689Abstract: Single piece ophthalmic inspection devices are provided having a continuous 3-dimensional molded surface preferably made out of plastic. The devices are relatively easier and cheaper to manufacture than existing inspection lenses. The smooth continuous edges are advantages to prevent damage to tissue as well to stop foreign objects accumulating in e.g. the clear regions of the lens. Ergonomic features built into the ophthalmic inspection device provide for superior control of the device on the patient's eye. In addition, textured knurled or grooved surfaces provide desired finger grip and control of the device.Type: GrantFiled: July 2, 2014Date of Patent: August 14, 2018Assignee: EXCEL-LENS, INC.Inventor: David H. Mordaunt

Patent number: 9895056Abstract: An ophthalmic laser illuminator 10 includes multiple laser devices 12-16. There are at least three different wavelengths of light emitted by the multiple laser devices 12-16 and each wavelength of light emitted by each laser device is outside of wavelengths blocked by a safety filter used for surgical treatment lasers 52. A controller 18 controls the multiple laser devices 12-16. A graphical user interface 32 is operably attached to the controller 18 for allowing a user to select a plurality of light parameters for a light beam exiting the illuminator 10.Type: GrantFiled: November 6, 2013Date of Patent: February 20, 2018Assignee: Bausch & Lomb IncorporatedInventors: David K.

Patent number: 9872797Abstract: A laser-assisted method for fully or partially separating tissue such as collagen containing tissue is provided. In one embodiment, the method pertains to a capsulorhexis whereby the laser-assisted method is applied to the lens capsule. A light-absorbing agent is added into or onto the tissue. A light beam with a wavelength capable of being absorbed by the light absorbing agent is then directed at the tissue to cause a thermal effect at the tissue following a predetermined closed curve with the goal to avoid irregularity or potential tears in the resulting rim of the tissue.Type: GrantFiled: January 17, 2017Date of Patent: January 23, 2018Assignee: EXCEL-LENS, INC.Inventor: David H. Mordaunt

Publication number: 20170266042Abstract: 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: ApplicationFiled: June 1, 2017Publication date: September 21, 2017Inventors: DANIEL V. PALANKER, MARK S. BLUMENKRANZ, DAVID H. MORDAUNT, DAN E. ANDERSEN

Patent number: 9610124Abstract: A medical laser using solely an electronic shutter circuit for controlling the laser output, without any mechanical shutter mechanism, is provided for use in clinical applications. The medical laser has several advantages compared to medical lasers with mechanical shutters. These advantages can be defined in terms of the speed of the electronic shutter, increased reliability, increased safety, smaller and less expense. The medical laser according to the invention will shut the laser down in less than 100 microseconds making it far superior to what would be possible with a typical mechanical shutter which would take at least 10 ms to disable the laser. Safety and reliability is a result of an electronic shutter circuit with at least two current sensors, at least two photodetectors and a set of one, two or three fast electronic safety switches.Type: GrantFiled: March 24, 2012Date of Patent: April 4, 2017Assignee: Precision Medical Optics, LLCInventors: David H Mordaunt, Charles M East
