Publication number: 20240139031Abstract: An ophthalmic laser treatment delivers patterned laser energy to an eye of a patient. A pattern-scanning laser device of the laser treatment system includes a laser module, a scanning module and delivery optics. The laser module generates laser energy (e.g. via a green laser diode), which is directed to the scanning module via a fiber optic cable. The scanning module produces the patterned laser energy by reflecting the laser energy into the delivery optics at different angles via a dielectric MEMS scanning mirror. The delivery optics includes an F-theta lens, a motorized and wirelessly-controlled spot-size selector module, and a focusing lens. A mobile computing device receives parameter information via a graphical user interface or voice control and sends the parameter information to the pattern-scanning laser device. In response to receiving activation signals from an activation unit, the pattern-scanning laser device emits the patterned laser energy based on the parameter information.Type: ApplicationFiled: December 29, 2023Publication date: May 2, 2024Inventors: Thomas Buss, Greg Fava, Mariafernanda Vilera Suárez, Peter Skovgaard

Patent number: 11684514Abstract: A laser module produces pulsed laser energy in a wavelength range of 495-580 nm based on duration, peak power, and interval parameter information. An envelope timer controls the total duration of all micropulses based on the duration and interval parameters via a pulse-width modulated (PWM) output to a micropulse timer, which in turn outputs a PWM micropulse signal. A light emitting diode driver outputs a laser current through a diode based on the micropulse signal and a dimming signal to produce the pulsed laser energy. The integrator compares a signal corresponding to a detected power level of the laser energy to a signal corresponding to the peak power parameter and outputs the dimming signal. The resulting micropulse durations are in the range of 50 to 300 microseconds for periods of about 2 milliseconds, with a duty cycle ranging from 5 to 15%. The overall pulse parameters are duration from 10 microseconds to 1.5 seconds, with periods of any value.Type: GrantFiled: September 26, 2019Date of Patent: June 27, 2023Assignee: Norlase ApSInventors: Greg Fava, Bjarke Goth, Peter Skovgaard

Publication number: 20220322937Abstract: A system for retrofitting a legacy binocular indirect ophthalmoscope (BIO) device with a camera includes an assembly with a mechanism for attaching to a mounting bracket of the BIO device in place of a teaching mirror. The assembly houses a beam splitter, which allows a portion of light from a viewing target to enter an entrance aperture of the BIO device while reflecting another portion of the light. A positioning mechanism positions the camera such that the light that is reflected by the beam splitter is directed to and captured by the camera to generate image data providing the same view(s) of the viewing target as presented via the BIO device. The image data is stored and/or wirelessly broadcast to viewing devices. The capture/storage functionality is activated via an actuator housed with a condensing lens for the BIO device and/or via a voice control module based on recognized voice commands.Type: ApplicationFiled: April 12, 2022Publication date: October 13, 2022Inventor: Greg Fava

Publication number: 20220211264Abstract: A body-mounted laser-indirect ophthalmoscope (LIO) system for delivering laser energy into an eye of a patient includes a wearable assembly which secures a control module, laser module, and/or power module (including a battery) to the body of the user. The control module receives activation signals and parameter information from an activation unit a mobile computing device and controls the laser energy emitted by the laser module based on the parameter information. The parameter information is user-provided via a graphical user interface or by voice control (e.g. recognizing voice commands in audio data captured by the mobile computing device). In the preferred embodiment, the wearable assembly includes only a headset, in which case the control, power and laser modules are provided on the headset; however, an alternative embodiment includes a utility belt from which a fiber optic cable for emitting the laser energy is routed to the headset.Type: ApplicationFiled: March 25, 2022Publication date: July 7, 2022Inventor: Greg Fava

Publication number: 20210366482Abstract: A voice control system for ophthalmologic laser treatment systems sets parameters for delivering laser energy based on voice commands and prevents potentially harmful parameters due to operator mistakes and misunderstood voice commands by providing incremental parameter adjustment and restricting the amount by which the parameters can be adjusted for each executed voice command. Valid voice commands include indications of which parameter to set, a value for the parameter, and whether to increase or decrease the value of the parameter. In one example, parameter values can only be increased or decreased by a certain percentage with respect to the current value. In another example, the parameters are adjusted by selecting the next highest or lowest value with respect to the current parameter value from a predetermined sequence of possible values for particular parameters. Voice control functionality can also be deactivated under certain conditions such as when it is determined that a parameter was not set.Type: ApplicationFiled: August 5, 2021Publication date: November 25, 2021Inventors: Greg Fava, Peter Skovgaard
