A method and device is provided for forming discernable markings within the cornea of an eye. Using a lens having a focal length to communicate and focus a laser to a focal point within the corneal layer of an eye, temporary markings can be formed within the corneal layer below its exterior surface. So formed the markings will remain for a number of days and provide the surgeon the ability to use the markings during eye surgery.

A surgical instrument for marking spots at locations on the scleral limbal surface of a human eye. The instrument includes an elongated handle dimension to be handheld. A first elongated pointer extends substantially axially outwardly from one end of the handle. This pointer has a pointed free end which, when pressed against the scleral limbal surface, creates a depression in the scleral surface having a first area. A second elongated pointer also extends substantially axially outwardly from the end of the handle. The second pointer has a blunt free end which, when pressed against the scleral limbal surface, creates a depression in the scleral surface having a second area which is several times in magnitude the area of the first area.

The present invention provides methods and systems for an eye marker device that includes a handle, a tip engaged to the handle and includes a marking means with at least one arm containing a marking apparatus, a rotational scale, and a servo motor.

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.

Zero parallax visual axis glasses for corneal pre-marking include a target light, an alignment light, a polarized lens and a short pass filter. In some embodiments the targeting light and/or alignment light are LEDs and/or configured to blink. In some embodiments the target light is red. In certain embodiments the alignment light is white. The polarized lens can be placed on a user's non-dominant eye and block light originating from the target light and/or alignment light. The short pass filter can be configured to allow light from the target light to only pass through in one direction.

A corneal marking system, and methods for its use, has a tilt-detecting device attached to a corneal marker, adapted to produce a signal when the corneal marker is in a horizontal position. Use of measurement devices may be coordinated between the marker and a level-measuring device positioned on a patient's head. Devices capable of measuring one, two or three axes are used and processors are provided to evaluate the data produced by the devices and provide a physician with a signal that the positions of the patient's head and the marker are such that an accurate marking procedure can be performed.

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.

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 incisional instrument and method of use for creating accurate, reproducible surgical incisions. An exemplary embodiment includes an incisional instrument configured for attachment to a patient's eye and for use performing arcuate limbal relaxing incisions (LRIs). The incisional instrument is made up of two coaxial, interconnecting pieces: a docking piece and a cutting piece. The docking piece includes a suction mechanism and is configured for being secured to a patient's eye just outside the corneal limbus. The cutting piece is configured to fit flush within the docking piece and includes cutting blades and one or more handles for rotating the cutting piece relative to the docking piece. When assembled, the cutting blades extend beyond the proximal end of the docking piece by a length equal to the desired depth of LRIs to be cut. The incisional instrument further includes measurement markings for properly positioning and measuring incisions.
