A length or strand of resilient material is formed into a continuous ring having multiple tissue-engaging portions for engaging and spreading eyeball tissue segments apart. The strand is formed with elongated straight sides joined by corner portions which are enlarged in directions transverse to the length dimension of each adjacent side. The corner portions constitute the tissue-engaging portions and have top and bottom sections and a connecting section that forms a gap for receiving the tissue. Each side of the ring extends from a bottom section of one corner to a top section of an adjacent corner. When the ring is deployed, the tissue is captured in the gaps at the corners of the ring and also is engaged along each side as that side transitions from a position situated below the tissue to a position situated above the issue.

A surgical clamp for aligning the margins of incised or wounded tissue has jaws with parallel clamping faces, and a handle for manipulating the clamp to align the margins of the tissue. The jaws are in a normally closed position, however they can be opened by compressing the handle to open the jaws. Prongs project from the inferior surface of the jaws. The clamp is positioned in a desired position over the margins of a wound to be closed, the prongs engage the margins of the wound to be aligned, and the jaws are closed by releasing compressive force on the handle. As the jaws close the prongs help move the tissue into alignment. Suture guide slots through the jaws assist in the placement of precisely placed sutures across the incision. The disclosed surgical clamp is particularly suited for selectively closing and reopening surgical incisions, such as a sclerotomy incision in the eye. Methods are disclosed for using the clamp during intraocular and other surgical or minimally invasive procedures. In one example the clamp is used during implantation into the retina of a scaffold on which choroid and retinal pigment epithelium cells and retina grow in a three-dimensional matrix that mimics the native structure of the retina.

Packaging for a medical device, such as but not limited to an eyelid speculum, is provided. The packaging enables for the shipment, storage, sterilization of the medical device in a secure and efficient manner while also maintaining the sterility of the device post-sterilization and allowing for the easy removal of the medical device from the packaging without compromising the device's sterility.

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 ring structure is configured to sit on a surface area of an eye, the ring structure having a top surface and a bottom surface, wherein the bottom surface is configured to touch the eye. A plurality of light-emitting elements is configured in the ring structure and a plurality of apertures is configured on the bottom surface of the ring structure, wherein the plurality of light-emitting elements is aligned with the plurality of apertures. A signal carrier runs along at least a portion of the ring structure, the signal carrier having one end configured to connect to a signal source and receive at least one of light and electricity from the signal source, and one or more opposite ends respectively coupled with the plurality of light-emitting elements.

An anterior chamber maintainer (ACM) is fastened to the cornea of a patient's eye at one or more, or potentially two or more, points of contact. The ACM can be inserted through a first and a second incision. The ACM can be fastened to each of the two incisions using fasteners. The ACM includes openings to provide irrigation solution to maintain the volume of the patient's eye during cataract surgery. The shape of the openings can be customized to reduce the amount of turbulence caused by the irrigation solution.

The present invention features devices, systems, and methods of use thereof for delivering therapeutic or sterilizing ultraviolet (UV) radiation, such as UVC or UVA radiation.

A device includes a body configured to be placed on an eye and multiple tine assemblies configured to secure the body to and release the body from the eye. The body includes multiple corners and multiple sides. Each corner includes a passage through the corner. Each side connects an adjacent pair of corners. Each tine assembly includes a twist pick configured to be inserted through one of the passages. Bottom surfaces of the sides are raised relative to bottom surfaces of the corners such that the bottom surfaces of the sides are spaced apart from the eye when the bottom surfaces of the corners are resting on the eye. Each of at least one side includes multiple openings configured to allow manipulation of a position of the body and a groove configured to receive a projection from a surgical tool in order to position the surgical tool on the eye.

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.

A length or strand of resilient material is formed into a continuous ring having multiple tissue-engaging portions for engaging and spreading eyeball tissue segments apart. The strand is formed with elongated straight sides joined by corner portions which are enlarged in directions transverse to the length dimension of each adjacent side. The corner portions constitute the tissue-engaging portions and have top and bottom sections and a connecting section that forms a gap for receiving the tissue. Each side of the ring extends from a bottom section of one corner to a top section of an adjacent corner. When the ring is deployed, the tissue is captured in the gaps at the corners of the ring and also is engaged along each side as that side transitions from a position situated below the tissue to a position situated above the issue.

In one embodiment, an illumination system includes a speculum having two arms coupled to blades at distal ends thereof and a biasing member at proximal ends thereof. One or more optical fibers are disposed through at least one of the arms and have one or more termination points located within at least one of the blades. The optical fibers are configured to deliver light to an interior space of an eye when the eye is coupled to the speculum. In some embodiments, the illumination system further includes a temple support pad.
