    Abstract: A surgical instrument for ophthalmic surgery includes a handle comprising a distal end and a probe comprising a proximal end coupled to the distal end of the handle. In some embodiments, a micro-structure pattern or a coating is formed on a surface of the probe. The surgical instrument further includes a driver in communication with the probe that is configured to cause vibration of the probe. The micro-structure pattern or coating and the vibration may be configured to reduce adhesion of the probe to a vitreous of an eye.

    Abstract: Embodiments of the present disclosure generally relate to an ophthalmic surgical probe for extrusion. In certain embodiments, the probe includes a beveled probe tip that increases the area of vacuum generation at a target site without increasing probe gauge, thus facilitating improved tissue engagement. In certain embodiments, the probe further includes one or more texturized surfaces for improved “grabbing” and manipulation of target tissues, and/or one or more surfaces formed of polymeric materials to reduce unwanted damage and enhance the safety of use thereof.

    Abstract: Certain embodiments herein relate to a method for use by an ophthalmic visualization device in providing ophthalmic visualization of an eye of a patient. In certain embodiments, the method includes, receiving an indication indicative of a material occupying a vitreous cavity of the eye. The method further includes determining, based on the indication, adjustment configurations for adjusting one or more optical elements of the ophthalmic visualization device. The method further includes automatically adjusting the one or more optical elements of the ophthalmic visualization device. The method also includes providing visualization of the eye using the adjusted one or more optical elements.

    Abstract: Microsurgical instruments having combined illumination, laser ablation, and viscoelastic injection functions. A surgical instrument includes a probe having a main lumen and a port at a distal end thereof. The probe may further include one or more optical fibers within the main lumen, the optical fibers configured to project laser light and illumination light. Laser light may be emitted from the distal end of the probe for disrupting an ocular tissue, while illumination light may be simultaneously emitted, axially or laterally, to provide enhanced visualization of the intraocular space during tissue disruptance. Upon disrupting the tissue, a viscoelastic fluid may be injected from the port to maintain an integrity of the intraocular space.

    Abstract: The present disclosure generally relates to surgical instruments having adjustable stiffness, and more particularly, surgical instruments having adjustable stiffness for ophthalmic surgical procedures. In one embodiment, a surgical instrument includes a probe, a slidable support sleeve, and a rotatable knob. A stiffness level of the probe may be adjusted by rotating the knob, thereby causing linear displacement of the support sleeve along a length of the probe. The knob may further include a dial depicting a series of settings representing different eye sizes and corresponding to preset positions of the support sleeve relative to the probe. Thus, a user may select an optimal stiffness of the probe for a particular eye size by rotating the knob to the corresponding setting.

    Abstract: Certain aspects of the present disclosure provide a voice-controlled system for controlling devices and systems in a surgical setting. The voice-controlled system includes at least one microphone and at least one loudspeaker distributed within the surgical setting to receive and audibly respond to voice commands from operating staff. In certain aspects, the at least one microphone and at least one loudspeaker include a phased microphone array and a phased loudspeaker array that are coordinated and synchronized to perform active noise reduction, echo cancellation, and directional determination of sound sources. The voice-controlled system performs tasks, such as activation of surgical devices, based on verbal interactions with the operating staff through the at least one microphone and at least one loudspeaker. In certain aspects, the voice-controlled system is configured to recognize, decipher, and prioritize natural language commands from different operating staff, and further provides pre-programming of device settings and operating staff pre-sets.

    Abstract: The present disclosure generally relates to a surgical instrument. The surgical instrument includes a base unit and a probe. The probe is disposed through an opening in a distal end of the base unit. The probe includes a port formed proximate to a distal tip of the probe. The distal tip includes a window, a lumen formed through the probe, and one or more optical fibers disposed in the lumen. The one or more optical fibers project a first laser light for irradiating an area proximate to the port to cut collagen fibers of vitreous material aspirated through the port. The one or more optical fibers further project a second laser light for cauterizing bleeding in an intraocular space of a patient.

    Abstract: Particular embodiments include, by a computing device, receiving one or more wavefront elevation maps for a patient's eye and identifying one or more attributes of the one or more wavefront elevation maps corresponding to vitreous floaters. The one or more attributes may include localized spatial variation of the one or more wavefront elevation maps; temporal variation among a plurality of wavefront elevation maps; and depth information indicating scattering of light from within the vitreous of the patient's eye. A machine learning model may be trained and utilized to characterize vitreous floaters based on the one or more wavefront elevation maps and other patient data. The wavefront elevation maps may be measured using an aberrometer. The aberrometer may be integrated with a LIDAR system to estimate depth of scattered light. A common laser light source may be used for both the aberrometer and the LIDAR system.
