Abstract: A process of making a diverging-light fiber optics illumination delivery system includes providing a micro-post comprising a glass-ceramic light-scattering element that includes at least one of a ceramic, a glass ceramic, an immiscible glass, a porous glass, opal glass, amorphous glass, an aerated glass, and a nanostructured glass; and fusion-splicing the glass-ceramic micro-post to the optical fiber by pulling an arc between electrodes across a gap formed by the optical fiber and the glass-ceramic micro-post; maintaining the arc for a time sufficiently long to make facing surfaces of the optical fiber and the micro-post one of malleable and molten; and pushing and thereby fusing together the facing surfaces of the optical fiber and the micro-post. Some embodiments can include fusing the glass-ceramic micro-post to the optical fiber by applying a laser beam to heat up at least one of the facing surfaces of the optical fiber and the glass-ceramic micro-post.

Abstract: A system, method, and apparatus for displaying a fused reconstructed image with a multidimensional image are disclosed. An example imaging system receives a selection corresponding to a portion of a displayed multidimensional visualization of a surgical site. At the selected portion of the multidimensional visualization, the imaging system displays a portion of a three-dimensional image which corresponds to the selected multidimensional visualization such that the displayed portion of the at least one of the three-dimensional image or model is fused with the displayed multidimensional visualization.

Abstract: Systems, methods, and devices for inserting an intraocular lens (IOL) assembly into an eye may be provided. An example optic management system may include a housing having a first end and a second end and a first side extending between the first end and the second end. The housing may include a cavity formed in the first side of the housing and configured to accommodate an intraocular lens, wherein the cavity comprises a first end portion, a second end portion, and a central portion. The housing may further include a bore formed in the housing, wherein a first portion of the bore extends from the first end to the cavity. The haptic optic management system may further include a ceiling disposed on the first side of the housing. The haptic optic management system may further include arms pivotably coupled to the housing in the cavity.

Abstract: In certain embodiments, a system for aligning an eye with a patient interface of a laser device includes a camera, a display screen, and a computer. The camera records images of the eye through the patient interface of the laser device. A liquid is disposed between and is in contact with the patient interface and the outer surface of the eye. The images include an outline of the liquid. The display screen displays the images of the eye. The computer aligns the eye with the patient interface by: identifying the outline of the liquid in an image received from the camera; determining a misalignment of the eye according to the outline; and instructing the display screen to display a description of the misalignment.

Abstract: An eye surgery tool with an implement having a curved shape memory region that is straightenable for accessing an interior of an eye. Upon accessing the eye interior, the implement may take on a natural curve shape. The implement may include a cutting region or edge that is of a rigidity greater than that of the shape memory material constituting the majority of the shape memory region. In spite of the added rigidity, the shape memory material may serve as a master in a master-slave arrangement to curve the cutting region or edge as appropriate.

Abstract: Systems and methods for tracking eye movement during a diagnostic procedure include a retina imaging system configured to capture a first plurality of images of an eye and detect a presence of a fovea, an eye tracker configured to capture a second plurality of images of the eye and track a position and orientation of the eye; and a control processor configured to synchronize the first and second plurality of images, determine a time at which the fovea is detected in the first plurality of images, and determine one or more images from the second plurality of images to be classified as representative of fixation. The classified images are analyzed to determine eye fixation status during the diagnostic procedure based on eye tracking data.
