The present invention provides methods and systems for an eye marker device that includes a handle having an interior cavity, a marking device coupled to the handle, and a rotational scale for providing a visual representation of the angle of the marking device relative to a predetermined origination point.

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.

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.

A corneal marking system is disclosed. The system has a corneal marker with at least one projection for marking the human eye. The system further has a measurement device capable of taking measurements of the human eye. The system further has an indicator that is connected to the measurement device via a signal path. The signal path is configured to permit communication of at least one signal from the measurement device to the indicator such that the indicator provides an indication to a user of the corneal marking system.

A conformable covering comprises an outer portion with rigidity to resist movement on the cornea and an inner portion to contact the cornea and provide an environment for epithelial regeneration. The inner portion of the covering can be configured in many ways so as to conform at least partially to an ablated stromal surface so as to correct vision. The conformable inner portion may have at least some rigidity so as to smooth the epithelium such that the epithelium regenerates rapidly and is guided with the covering so as to form a smooth layer for vision. The inner portion may comprise an amount of rigidity within a range from about 110-4 Pa*m3 to about 510-4 Pa*m3 so as to deflect and conform at least partially to the ablated cornea and smooth an inner portion of the ablation with an amount of pressure when deflected.

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.

A corneal marking system and methods for its use, has a first tilt-detecting device attached to a corneal marker, adapted to produce a signal when the corneal marker is in a horizontal position. In another version, the first tilt-detecting device is adapted to produce a signal when the corneal marker is in tilted to a pre-selected value and a second tilt-detecting device is attached to the patient's head to measure the tilt of the head and is adapted to produce a signal when the head is tilted to match the pre-selected value of the first tilt-detecting device. In a third version, the first and second tilt detectors send signals to a signal detector which emits a signal when the first and second tilt detectors indicate substantially the same amount of tilt. In each case, the cornea is marked when the appropriate signal is emitted.

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.

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 conformable covering comprises an outer portion with rigidity to resist movement on the cornea and an inner portion to contact the cornea and provide an environment for epithelial regeneration. The inner portion of the covering can be configured in many ways so as to conform at least partially to an ablated stromal surface so as to correct vision. The conformable inner portion may have at least some rigidity so as to smooth the epithelium such that the epithelium regenerates rapidly and is guided with the covering so as to form a smooth layer for vision. The inner portion may comprise an amount of rigidity within a range from about 1104 Pa*m3 to about 5104 Pa*m3 so as to deflect and conform at least partially to the ablated cornea and smooth an inner portion of the ablation with an amount of pressure when deflected.
