Abstract: An ophthalmic surgical system can include a light source configured to generate a light beam and a filter wheel disposed between the light source and an intraocular illumination device. The filter wheel can include an unfiltered area, a first filtered area, and a second filtered area. The first and second filtered areas can limit transmission of certain wavelengths of the light beam to the intraocular illumination device. The system can include an actuator configured to selectively move the filter wheel to cause the light beam to pass through the unfiltered area, the first filtered area, and/or the second filtered area. The system can include a computing device configured to provide a control signal to the actuator. The computing device can be configured to provide a control signal to the actuator based on a beam location, a beam composition, an exposure time, and/or a limited visibility condition.

Abstract: An ophthalmic surgical microscope can include a movable optical element positioned in an optical pathway of light reflected from a surgical field. The movable optical element can be configured to oscillate in a direction along the optical pathway. The microscope can include an actuator coupled to the movable optical element and configured to move in response to a control signal. The microscope can include a computing device in communication with the actuator and configured to generate the control signal to move the movable optical element. In some embodiments, the computing device is configured to generate the control signal to move the movable optical element with an oscillation frequency greater than the critical flicker fusion rate.

Abstract: Systems, methods, and computer-readable media for automatically controlling a lens to cornea standoff. Automatic lens to cornea standoff control can include an ophthalmic microscope with a lens arrangement configured for viewing images of an eye, a front lens assembly with a high diopter lens for resolving an image of a posterior portion of the eye, and a sensor to monitor a distance between the high diopter lens and a surface of the eye. Automatic lens to cornea standoff control can also include a control system for receiving distance information and an actuator for the front lens assembly back to the threshold standoff distance, past the threshold standoff distance, etc.

Abstract: Described herein is an arm stabilization member for dampening inadvertent movement of the arm of a user during a surgical procedure, comprising an arm support and a movement mechanism coupled to the arm support. The arm support comprises an outer frame sized to support at least a portion of the user's arm and an inner pad lining an inner surface of the outer frame and configured to conform to the user's arm. The movement mechanism comprises a counterbalance system movably connected by joints and configured to compensate for the gravitational forces exerted by the arm of the user.

Abstract: Curvature of field transformation of OCT images during ophthalmic surgery may be performed with an OCT scanning controller that interfaces to an OCT scanner used with a surgical microscope. Real-time OCT images may be acquired by the OCT scanner, while an anamorphic transformation is applied to the OCT images to match the curvature of field for optical images viewed using the surgical microscope. The transformed OCT images may be displayed during surgery.

Abstract: Resolution enhancement of OCT images during ophthalmic surgery may be performed with an OCT scanning controller that interfaces to an OCT scanner used with a surgical microscope. Real-time OCT images may be acquired by the OCT scanner, while previously acquired high resolution OCT images are accessed by the OCT scanning controller. The high resolution OCT images may be morphed based on the real-time OCT images to match a deformation of the eye. The morphed high resolution OCT images may be displayed during surgery.

Abstract: A pair of objective lenses is integrated into a top surface of a surgical contact lens. The pair of objective lenses replaces the conventional single, shared objective lens that is typically positioned 175 mm from the ocular surface. In one example, a surgical contact lens for providing a stereo-optic view inside a patient's eye includes a first side adapted to engage the patient's eye and a second side facing away from the patient's eye. The second side includes a first optical component arranged to focus light from a first position and a second optical component arranged to focus light from a second position that is different from the first position. The first optical component is substantially coplanar with the second optical component.
