Publication number: 20230355438Abstract: Intraocular drainage devices are provided. An intraocular drainage device includes a drainage tube that provides for increased drainage of aqueous humour from the anterior chamber of the eye. A self-clearing device is disposed within the drainage tube. The self-clearing device provides an increased fluid flow path within the drainage tube in response to clotting from the body or clogging from debris in the aqueous humour. Methods of manufacturing intraocular drainage devices and methods of inserting intraocular drainage devices into the eye are also provided.Type: ApplicationFiled: October 12, 2021Publication date: November 9, 2023Inventors: John KOONTZ, Eric PORTEOUS, Jason MOHR, Khalid MANSOUR

Publication number: 20230301832Abstract: Ophthalmic devices include a housing and a cannula extending from the housing, the cannula having a lumen for fluid flow, a reservoir for holding fluid and an activation assembly. The activation assembly includes a rotatable wheel and a moveable housing ring coupled to the wheel, the coupled rotatable wheel and moveable housing ring configured to move inward together towards an interior of the housing when an inward force is applied to the wheel and to move outward together away from the interior of the housing when an outward force is applied to the coupled wheel and the moveable housing ring. Methods of operating ophthalmic devices are also provided.Type: ApplicationFiled: March 20, 2023Publication date: September 28, 2023Inventors: Khalid MANSOUR, Malik Y. KAHOOK, John KOONTZ, Jason MOHR, Eric PORTEOUS, Dustin TOBEY

Publication number: 20210212859Abstract: An ophthalmic device and methods of its use can be applied for treatment of various conditions including eye diseases, such as glaucoma, using minimally invasive surgical techniques. The ophthalmic device can be used to cut the trabecular meshwork (TM) in the eye. The device tip provides entry into the Schlemm's canal and ramped portions elevate the TM under tension and guide it to lateral blades. An entire strip of TM can be removed without leaving TM leaflets behind and without causing collateral damage to adjacent tissues.Type: ApplicationFiled: September 20, 2019Publication date: July 15, 2021Inventors: John KOONTZ, Eric PORTEOUS

Patent number: 10638080Abstract: The disclosure provides a system including an augmented reality device communicatively coupled to an imaging system of an ophthalmic microscope. The augmented reality device may include a lens configured to project a digital image, a gaze control configured to detect a focus of an eye of an operator, and a dimming system communicatively coupled to the gaze control and the outer surface and including a processor that receives a digital image from the imaging system, projects the digital image on the lens, receives a signal from the gaze control regarding the focus of the eye of the operator, and transitions the outer surface of the augmented reality device between at least partially transparent to opaque based on the received signal. The disclosure further includes a method of performing ophthalmic surgery using an augmented reality device and a non-transitory computer readable medium able to perform augmented reality functions.Type: GrantFiled: January 24, 2018Date of Patent: April 28, 2020Assignee: ALCON INC.Inventors: Mikhail Ovchinnikov, John Koontz, Andrew Steven Hopper, Cesario Dos Santos

Patent number: 9797390Abstract: A roller assembly comprises a central section with a hub; a plurality of arms coupled to the central section, each arm having a radial section, an arcuate section, and a bent section; and a plurality of rollers, one roller coupled to the bent section of each arm. The arms may be flexible such that the rollers are capable of moving with respect to the central section when the arms flex. The rolling surface of the rollers is arranged to engage a polymer sheet or flexible tubing throughout travel of the arms.Type: GrantFiled: May 30, 2013Date of Patent: October 24, 2017Assignee: Novartis AGInventors: Gary P. Sorensen, John Koontz, Gregory S. Layser

Patent number: 9089367Abstract: In various embodiments, a surgical console may include a sensor strip with sensor strip sensors (e.g., field effect or capacitive sensors) offset vertically and configured to receive an input from a user corresponding to a vertical height of a patient's eyes relative to the surgical console. The surgical console may use the input from the sensor strip to determine a patient eye level (PEL) relative to a surgical console component and then use the PEL and the at least one component in controlling operation of at least one of a source of irrigation or a source of aspiration during an ophthalmic procedure. The surgical console may further include a plurality of visual indicators positioned relative to at least two of the plurality of sensor strip sensors and configured to be illuminated to correspond to a sensor detecting the touch input.Type: GrantFiled: April 7, 2011Date of Patent: July 28, 2015Assignee: Alcon Research, Ltd.Inventors: David A. Thoe, John Koontz, Mikhail Boukhny

Patent number: 8684145Abstract: In various embodiments, a braking system may include an actuator, a pawl gear coupled to the actuator, and a wheel gear plate. The braking system may further include a brake pad, an outer wheel coupled to the brake pad, and a spring washer plate configured to press the wheel gear plate against the brake pad such that the wheel gear plate is configured to inhibit rotation of the outer wheel through friction between the wheel gear plate and the brake pad when the pawl gear inhibits rotation of the wheel gear plate. In some embodiments, the braking system may further include a sensor and the actuator may be triggered to actuate the pawl gear in response to signals from the sensor.Type: GrantFiled: January 31, 2011Date of Patent: April 1, 2014Assignee: Alcon Research, Ltd.Inventors: Mikhail Boukhny, David A.
