The surgical instrument may include a handpiece configured for grasping by a user for fluid injection. The handpiece may include a first lumen disposed therein and an actuatable toggle movably coupled with the handle. The surgical instrument may further include a cannula coupled to the handpiece and configured to be introduced into an eye. The cannula may include a second lumen extending therethrough and a needle movably disposed within the second lumen. The needle may be coupled with the actuatable toggle and configured to extend from and retract into the second lumen at a distal end of the cannula upon actuation of the toggle.

    Abstract: An ophthalmic lens includes an optic comprising an anterior surface, a posterior surface, and an optical axis. At least one of the anterior surface and the posterior surface has a surface profile including a base curvature, a refractive region having the base curvature, and a diffractive region comprising a diffractive profile including a plurality of diffractive steps. At least a portion of the diffractive profile constitutes a combination of a base diffractive profile defining multiple foci for the ophthalmic lens and an achromatizing structure that reduces longitudinal chromatic aberrations.

    Abstract: The disclosure provides a method for correcting higher-order aberrations including providing a laser radiation. The method also includes controlling a location of a beam focal point of the laser radiation by a system of scanners and guiding the beam focal point in such a way that the location of the beam focal point is in a cornea of an eye. The method further includes introducing the laser radiation into the cornea of the eye. The method includes cutting a lenslet, wherein a thickness of the lenslet t(X,Y) satisfies a following equation: t(X,Y)=t0+Δt(X,Y)/(n−1), where Δt(X,Y) represents a higher-order wavefront elevation and t0 represents the thickness of the lenslet having a spherical refractive power of D.

    Abstract: In certain embodiments, an ophthalmic surgical system for adjusting a dimension of an eye includes a camera and a computer. The camera generates a surgical image of the eye in contact with a patient interface, which distorts the cornea. The surgical image includes the pupil with a real pupil diameter. The computer accesses a diagnostic image of the eye with the cornea having a natural curvature. The natural curvature affects the real pupil diameter to yield a diagnostic pupil diameter of the diagnostic image that is different from the real pupil diameter of the surgical image. The computer adjusts the real pupil diameter of the surgical image using an eye model to yield a refracted pupil diameter that takes into account the curvature of the cornea and uses the refracted pupil diameter to compensate for the difference between the diagnostic and real pupil diameters.

    Abstract: A system includes a display device and an actuated structure mounted to the display device and configured to move the display device in three-dimensional space. The system includes an imaging device configured to capture images of a patient's eye during an ophthalmic surgery and display the images on the display device. A controller is configured to activate the actuated structure to maintain visibility of the display device to a surgeon performing the ophthalmic surgery. The display may be positioned based on a surgeon profile and/or a treatment plan. Whether the display is visible may be determined based on images from a camera mounted to the imaging device, the display device, or elsewhere. Whether the display is visible may be determined based on kinematic data for the actuated structure and/or a support for the imaging device.

    Abstract: A vitrectomy probe includes a probe body and a needle portion projecting from the probe body. The needle portion includes a tube which extends at least partially in the needle portion and at least partially in the probe body. A cutter is positioned inside the tube in the needle portion. The cutter is at least partially composed of a permanently magnetic material. A field-creation unit is adapted to create an induced magnetic field, with the cutter being movable between a first position and a second position based in part on the induced magnetic field. The tube may be at least partially composed of a temporarily magnetic material. In one embodiment, the field-creation unit includes a driving magnet positioned in the probe body and adapted to selectively magnetize the tube.

    Abstract: A method of deploying an ocular implant into Schlemm's canal of an eye. The method includes the steps of inserting a distal end of a cannula through a cornea of the eye and into an anterior chamber of the eye, the cannula having a distal opening extending from the distal end and through a side wall; placing the distal opening of the cannula into fluid communication with Schlemm's canal; advancing the ocular implant distally through the cannula with a delivery tool engaged with the ocular implant, a proximal portion of the ocular implant engaging the delivery tool proximal to a distal portion of the delivery tool; and disengaging the ocular implant and the delivery tool when the proximal portion of the ocular implant reaches the cannula distal opening. The invention also includes a system for practicing the method.
