International Classification:

G02F 1/01
G02B 27/14

US Classification:

359279, 359629

Abstract:

An adaptive optics system is provided, comprising a spatial light modulator configured to modulate an incoming beam with an aberrated wavefront, a beamsplitter configured to receive the modulated beam from the spatial light modulator and to divide the modulated beam into a measurement beam and a reference beam, a spatial filter configured to spatially filter the reference beam, and to interfere the spatially filtered reference beam with the measurement beam to form an interferogram, an imaging device configured to capture an image of the interferogram, and a processor configured to determine the aberrated wavefront and to provide control signals to the spatial light modulator to mitigate aberrations in the aberrated wavefront.

Abstract:

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.

International Classification:

A61F 9/007

US Classification:

604 31

Abstract:

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.

US Classification:

600249

Abstract:

A task light system for a surgical console includes a task light that can be held to a coupling location on a surgical console. The task light has an inductive coupling, a light source, and a goose neck connecting the light source to the inductive coupling. The coupling location is located on a face of the surgical console. The coupling location is configured to magnetically attract and hold the inductive coupling. The face of the surgical console where the coupling location is located is a continuous surface.

Abstract:

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.

Abstract:

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.
