The present disclosure relates to a structure used in an ophthalmic surgical procedure. The device may be used in pupil expansion or stabilization of the iris. The device is made out of an elastic or semielastic material in a shape that is conducive to easy insertion and removal as well as being optimized for atraumatic pupil expansion.

A contact lens for use with a surgical microscope may be equipped with an anti-fogging device to prevent obscuring the view of a surgeon due to condensation during ophthalmic surgery. The anti-fogging device may deliver thermal energy to a surface of the contact lens to heat the contact lens above an ambient dew point. The thermal energy may be delivered by an air duct with a fan nozzle, a fluid duct in thermodynamic contact with the contact lens circulating a heat transfer fluid, or generated with electrical energy to an electrical heating element disposed on the surface of the contact lens. The thermal or electrical energy may be delivered via a handle for supporting the contact lens during surgery.

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.

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 second incision. The ACM can be fastened to each of the two incisions using, for example, friction surfaces, ridges, a malleable tip, magnets, a segmented tip, or other types of 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. By fastening the ACM to the cornea, the ACM is less likely to shift around or become dislodged from the eye during surgery. The ACM can be integrated with iris retractors to hold the position of a floppy iris during surgery.

Apparatus and methods, and uses of apparatus, for preventing prolapse of iris tissue, through a surgical opening in the eye during eye surgery. Early in the surgery, one or more surgical openings are made in the eye, and a flexible biocompatible iris shield is inserted, through a such opening, into the anterior chamber and placed in a position whereby the iris shield overlies the iris anteriorly, adjacent each surgical opening and is positioned between the iris and any surgical openings. If/when the pressure inside the anterior chamber increases during surgery, any anterior movement of the iris toward the cornea or sclera in response to such pressure, moves the iris shield in an anterior direction, such that the iris shield remains between the iris and the surgical opening. Thus, the iris shield blocks the surgical opening and prevents movement of eye material, e.g. iris tissue, to and through the surgical opening.

The present disclosure is directed to a method and apparatus for holding an eyelid open and preventing involuntary blinking during an ultrasound imaging procedure while ensuring patient safety and comfort. Eyelids can be taped up to the forehead or down to the cheek with common medical tape; however, this does not provide the instrument operator with the ability to adjust or control the amount of eye lid opening very well, nor allow the patient to relax the eyelids between scanning sessions. The present disclosure includes a speculum that can be placed in an eye piece such as used in a precision ultrasound device or other imaging device wherein the optical acoustic and transmission path between the eye and instrument is formed by a fluid such as saline solution and distilled water.

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.

An eyelid manipulation device includes a rigid contact portion dimensioned to be insinuated between an eyelid and a globe, the contact portion having an upwardly-facing surface opposite a downwardly-facing surface, each of the surfaces extending between a distal side and a proximal side of the contact portion; and a rigid stem integral with and extending upwardly from the proximal side of the contact portion. In embodiments, the stem is connectable to a handle. In other embodiments, the stem is elongated, thereby serving as a handle. The eyelid manipulation device may be used during treatment of Meibomian glands or otherwise during treatment of dry eye symptoms.

To make it possible to improve user convenience, provided is a control device including: a control unit configured to control a position and an attitude of a microscope unit by driving an arm unit that supports the microscope unit on the basis of a captured image of an operating site photographed by the microscope unit during an operation so that a position and attitude condition set before the operation is satisfied. The position and attitude condition is a condition that prescribes a position and an attitude of the microscope unit with respect to the operating site to obtain a desired captured image corresponding to the position and attitude condition.

The present disclosure provides a deep orbital access retractor (DOAR) device which includes a manipulable body section including a compressible handle having a size and shape to be manipulated by at least two (2) digits of a clinician. A flexible head section having two (2) arms with each arm having a distal end and a proximal end, with the distal ends of the arms spaced apart forming a gap there-between at a distal tip section. A flexible flange material envelops and encloses the two arms and the gap and extends around a periphery of the flexible head section. A flexible diaphragm is attached to and extends between the two arms to provide a generally spoon-shaped flexible head section. The flexible head section is linked to the compressible handle section with the linkage being configured such that upon compression of the handle section the arms articulate with respect to each other thereby causing narrowing of the flexible head section to allow for insertion into the orbit and positioning between soft tissue and bone while the flexible diaphragm remains in sufficient tension to not obstruct the view of the operator into the orbit. When compression is released the flexible diaphragm develops sufficient tension and rigidity for applying sufficient force to retract the orbital contents of a patient to allow access to orbital walls.
