Various corneal marker tools and assemblies are provided for use in ophthalmic procedures to place ink marks on the cornea. One tool assembly includes an applicator containing an ink and a disposable marking tip attachable to the applicator, where ink is injected from the applicator into hollow channels of the marking tip. Another tool assembly includes a reusable handle and a disposable marking tip attachable to the handle. Another tool assembly includes a marker assembled with a cap with an ink pad. Another tool assembly includes a marker tool and a nesting adapter to be used with a patient interface device. Other tools have a one-piece design with a marker head and an handle fixedly joined together. Some tools have pre-inked marking elements, or an embedded light source, or a built-in level indicator, or a ring-shaped marker head, or a leaf spring feature on their marking prongs.

A device for marking a corneal surface of an eye includes a planar base having a central opening, a marking side, and a non-marking side, a linear marker extending across the central opening, and an outer circumference of the planar base having a wall extending vertically away from the non-marking side.

A surgical sizer for creating a tissue pocket for an implantable medical device may include a replica of the device and a (preferably ergonomic) handle portion, optionally with marking features that facilitate marking the tissue for precise implant placement and alignment.

A donor corneal tissue cutting blade provided with integrally formed asymmetrical markers for facilitation identification of the anterior and posterior sections or portions of the donor corneal tissue is disclosed. The blade is a cylindrical body having, in one embodiment, a U-shaped extension which cooperates with the body to define a keyway. Protrusions may be formed on the body and/or extension to provide further markers.

A device for applying a marking to the human eye, in particular to the cornea of the eye, comprises a marking head comprising a marking element and a holding device carrying the marking head or an intermediate adapter. The marking head or the intermediate adapter has a bearing area which is rotatably mounted in a bearing ring of the holding device which surrounds the bearing area in a predeterminable or variable angular position.

A device and method for marking corneal tissue. The device includes an ink reservoir portion and an ink resist portion. The ink reservoir portion is annular in shape and the ink resist portion occupies a central area within the annular shape. The ink reservoir portion and the ink resist portion are sized and structured to interface with the central cornea and to apply ink to the corneal tissue. The method includes applying ink to the cornea in an annular pattern.

An apparatus includes a body and a pair of rigid legs extending from the body. The body includes an engagement feature configured to engage a deployment instrument. The legs are parallel with each other. Each leg has a sharp tip. The legs both extend along a plane. The body defines a guide opening. The guide opening is oriented transversely relative to the plane associated with the legs. The guide opening is sized to receive a cannula having a generally flat profile. The guide opening is configured to guide the cannula through a sclerotomy at a substantially tangential orientation.

An ophthalmic marking device is provided herein for marking a patient's eye. The device may include a handle and a tip with a tip element, a first portion of the tip element protruding from the tip to be exposed. The tip element is electrically conductive to resistively generate heat with electrical flow therethrough. A source of electrical power is associated with the device and electrically coupled to the tip element. The source of the electrical power and the tip element are configured to cause the first portion of the tip element to have a temperature in a range of 250° F.-450° F. Advantageously, the subject invention provides for a relatively low-cost device for marking a patient's eye and allows for creating a less traumatic marking on a patient's eye as compared to higher temperature electrocautery devices.
