Publication number: 20230421737Abstract: A method for enhancing digital images during a microsurgery, e.g., an eye surgery, includes collecting digital images of target anatomy using a digital camera as the target anatomy is illuminated by warm white light. The method includes identifying, via a processor in communication with the digital camera, a predetermined stage of the microsurgery. Within the images, the processor digitally isolates a first pixel region, e.g., a pupil pixel region, from a second pixel region, e.g., an iris pixel region, and adjusts a characteristic of constituent pixels thereof. The method, possibly recorded as instructions in a computer-readable medium, may be used to enhance a red reflex at predetermined stages of an eye surgery. A system includes a lighting source for emitting warm white light having a color temperature of less than about 4000° K, the camera, and the processor.Type: ApplicationFiled: September 11, 2023Publication date: December 28, 2023Applicant: Alcon Inc.Inventors: Gillian Myers, Alan Fridman, Maximiliano Ramirez Luna

Publication number: 20230123717Abstract: A localization target for a digital surgical stereoscope is disclosed herein. In an example, the localization target includes a shell apparatus for a surgical imaging camera. The apparatus includes a top surface integrally formed with a front surface and two opposing side surfaces defining empty space therebetween. Each of the top surface, the side surfaces, and the front surface includes at least three tracking features. The apparatus also includes at least six kinematic constraints located on an internally facing side of at least one of the top surface, the side surfaces, or the front surface. The apparatus further includes a connector that is positioned within an area defined by the at least six kinematic constraints.Type: ApplicationFiled: October 17, 2022Publication date: April 20, 2023Inventors: Thomas Kanusky, Stephen Minne, Alan Fridman, Norman Hannotte

Patent number: 11571272Abstract: A stereoscopic camera with fluorescence visualization is disclosed. An example stereoscopic camera includes a visible light source, a near-infrared light source, and a near-ultraviolet light source. The stereoscopic camera also includes a light filter assembly having left and right filter magazines positioned respectively along left and right optical paths and configured to selectively enable certain wavelengths of light to pass through. Each of the left and right filter magazines includes an infrared cut filter, a near-ultraviolent cut filter, and a near-infrared bandpass filter. A controller of the camera is configured to provide for a visible light mode, an indocyanine green (“ICG”) fluorescence mode, and a 5-aminolevulinic acid (“ALA”) fluorescence mode by synchronizing the activation of the light sources with the selection of the filters. A processor of the camera combines image data from the different modes to enable fluorescence emission light to be superimposed on visible light stereoscopic images.Type: GrantFiled: July 7, 2021Date of Patent: February 7, 2023Assignee: Alcon, Inc.Inventors: Ashok Burton Tripathi, Maximiliano Ramirez Luna, George Polchin, Thomas Riederer, Alan Fridman
