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: A lens drying system includes a sterile gas supply, a supply line, and an annular body. The body is connected to the supply line and defines an internal channel. The internal channel, which is in fluid communication with the sterile gas supply via the supply line, defines a plurality of openings. The openings are collectively configured to direct a flow of a sterile gas, e.g., a filtered and desiccated medical grade gas, from the sterile gas supply onto a lens surface of an ophthalmic front lens. This occurs during a non-contact wide-angle visualization process to mitigate fogging of the lens surface. A processor of a surgical console may receive user preference settings, including a desired steady-state flow rate and/or a desired pulse rate of the sterile gas. The processor could then command the desired steady-state flow rate and/or a desired pulse rate from the surgical console.
