  • Patent number: 10285584
    Abstract: En face or 3D volumetric OCT imaging during ophthalmic surgery may be performed with an OCT scanning controller that interfaces to an OCT scanner used with a surgical microscope. The OCT scanner may generate en face images before and after surgical operations, such as retinal membrane peeling, are performed. Using digital subtraction on the en face images, an overlay image indicative of the changes from the surgical operations to the eye may be generated and overlaid onto an optical image displayed to a user of the surgical microscope.

  • Patent number: 10172516
    Abstract: A contact lens for use with a surgical microscope may be equipped with an anti-fogging device to prevent obscuring the view of a surgeon due to condensation during ophthalmic surgery. The anti-fogging device may deliver thermal energy to a surface of the contact lens to heat the contact lens above an ambient dew point. The thermal energy may be delivered by an air duct with a fan nozzle, a fluid duct in thermodynamic contact with the contact lens circulating a heat transfer fluid, or generated with electrical energy to an electrical heating element disposed on the surface of the contact lens. The thermal or electrical energy may be delivered via a handle for supporting the contact lens during surgery.

  • Publication number: 20180193192
    Abstract: The present disclosure describes systems and methods for pressure-driven micro-surgical tool actuation. The systems and methods may encompass the use of a remote handle held by a first hand of a user as well as a surgical tool located in the eye of a patient. A primary actuator may be included in remote handle and operable to be actuated by a mechanical force exerted on the handle. Actuating the primary actuator pressurizes a fluid within a length of tubing. The pressurized fluid may be transmitted to a dynamic tool held by a second hand of the user, where the pressurized fluid may be used to actuate a subordinate actuator. Actuation of the subordinate actuator may actuate a dynamic component of the dynamic tool.
