Techniques for fabrication of implant material for the reconstruction of fractured eye orbit may include using an image processing system to analyze a set of two-dimensional images representing a three-dimensional scan of a skull of a patient, automatically detect an orbital fracture in the skull based on the set of two-dimensional images, and identify which/both of the two eye orbits containing any orbital fracture. The techniques may further include, for each of the two-dimensional images in which the orbital fracture is detected, determining a region of interest, and extracting the region of interest. The techniques may further include generating a three-dimensional reconstruction model for the fractured eye orbit, and outputting model data for generating an implant mold for the fractured eye orbit.

In a first aspect of the subject invention, an iris expander is provided which includes a non-metallic, unitary, multi-segmented body which is expandable from a first state to a second state. The second state defines a larger footprint than the first state with the body being defined by a plurality of segments connected by living hinges. In a further aspect, an iris expander is provided which includes a multi-segmented body that is expandable from a first state to a larger-footprint second state. At least one aperture is formed in the body with a channel extending therefrom embedded in the body such that no portion thereof is exposed externally of the body. The channel is formed to accommodate a portion of an instrument for causing adjustment of the body with avoidance of direct contact of the instrument with the tissue of the iris.

Provided herein are cannula devices that are self-illuminating to facilitate visualization of the cannula devices during a surgical procedure. The self-illuminating feature may be provided by phosphors incorporated into the cannula device, for example in the hub or sealing element of the cannula device. The cannula device may emit light of a specific color selected to correspond to a size of the cannula device.

An eyelid eversion tool and a pair of disposable grippers for use with an eyelid eversion tool is described. The eyelid eversion tool includes a first arm and a second arm extending from a common joint end, the arms each, respectively, having a distal end opposite the common joint end; a first gripper fitted to the distal end of the first arm, the first gripper having a contact surface on an inward facing side thereof; and a second gripper fitted to the distal end of the second arm, the second gripper having a contact surface on an inward facing side thereof, where the contact surfaces face each other and are spaced apart, and the contact surfaces come into contact when the arms are compressed together, and where at least one of the grippers has an extender tab protruding from an outward facing side opposite its contact surface.

Systems and methods are provided for illumination of the periorbital exterior of the eye and the interior of the eye with a non-invasive (or non-penetrating), trans-corneal, trans-conjunctival, trans-scleral, non-incandescent, and/or low-temperature light source. In some examples, a speculum includes a first arm having one or more blades located at an end of the first arm and a second arm having one or more blades located at an end of the second arm, a set of light-emitting elements on the one or more blades, and a signal carrier running along at least a portion of the first and second arms and having one end configured to connect to a signal source to receive light and/or electricity and one or more opposite ends respectively coupled with the set of light-emitting elements, the signal carrier being configured to transmit the light and/or electricity from the signal source to the set of light-emitting elements.

An eye speculum including a frame and a first and a second holder movably mounted on the frame. A first retraction blade is secured to the first holder and a second retraction blade secured to the second holder. An adjustment mechanism is operably secured to the frame and to the first and second holders. The adjustment mechanism includes a rotatable actuating device engageable by a user, wherein rotation of the actuating device translates the first and second holders relative to each other to control a separation distance between the first and second retractor blades.

The devices and methods of the present invention provide a means to depress the sclera in such a fashion as to provide single point, multiple point, semicircular or 360° circumferential scleral tissue depression without the need for manual manipulation of the scleral depressor. The device comprises a shaped depressor for insertion between the sclera and the orbit of the eye and a holding means for positioning the depressor. In some embodiments the device can be integrated with a speculum. Use of the device eliminates the need to have a second person manipulate the depressor during the procedure and directly enables bimanual surgery.

Systems, devices and methods for dilating and/or expanding the iris of a patient's eye during eye surgery is disclosed, comprising an elastomeric ring made from biocompatible material having a groove formed therein for receiving and protecting the pupillary rim and iris, whereby, when the ring is inserted into the pupil of an eye of a patient, it mechanically dilates the pupil.

An eyelid eversion tool and a pair of disposable grippers for use with an eyelid eversion tool is described. The eyelid eversion tool includes a first arm and a second arm extending from a common joint end, the arms each, respectively, having a distal end opposite the common joint end; a first gripper fitted to the distal end of the first arm, the first gripper having a contact surface on an inward facing side thereof; and a second gripper fitted to the distal end of the second arm, the second gripper having a contact surface on an inward facing side thereof, where the contact surfaces face each other and are spaced apart, and the contact surfaces come into contact when the arms are compressed together, and where at least one of the grippers has an extender tab protruding from an outward facing side opposite its contact surface.

An exemplary method for expanding and maintaining an intraocular opening includes compressing along an axis a circular body comprising a first pocket, a second pocket, a third pocket and a fourth pocket positioned vertically below a top band section. Inserting intraocular tissue of an eye in the first pocket of the compressed circular body, thereby elongating the intraocular opening, and inserting the intraocular tissue in the second pocket and the third pocket as the body decompresses. Decompressing the body and inserting the intraocular tissue in the fourth pocket thereby expanding the intraocular opening.
