Surgical tool for forming incisions in ocular tissue with tip providing visibility and related apparatus and method
A surgical tool includes a housing having a driver and a surgical blade configured to be bi-directionally rotated by the driver. The surgical tool also includes a footplate configured to receive the surgical blade. The footplate includes a bottom portion configured to rest on ocular tissue of a patient's eye. The bottom portion includes a slot configured to allow passage of a portion of the surgical blade through the bottom portion of the footplate and into the ocular tissue of the patient's eye. The footplate also includes multiple walls having multiple openings. The openings are configured to receive additional portions of the surgical blade such that the surgical blade is rotatable relative to the footplate. The footplate further includes an additional opening or open side configured to allow viewing of the surgical blade and the slot during use.
DEVICES AND METHODS FOR OCULAR SURGERY
A hand-held aspiration device is provided which has a relatively small suction volume along a suction path to improve responsiveness of the aspiration device when the device is activated. The device may be manually powered and may be provided without electronic controls. The device has a suction path which may be purged into a disposal enclosure to reduce the volume of material under the influence of the suction pressure during the procedure. The suction source may also be part of the hand-held unit to further reduce the suction path and suction volume.

METHOD AND APPARATUS FOR INSERTING AN IMPLANT IN THE CORNEA OF THE EYE
Methods, devices, and systems are presented for inserting an implant in the cornea of the eye, where the implant is a microshunt; a microshunt delivery device for delivering the microshunt into the cornea may comprise the microshunt, an actuator, and a suction stabilizer; a vacuum device may be inserted in the stabilizer such that the cornea may be sucked onto a concave bottom side of the stabilizer; the microshunt may then be inserted into a hole in the suction stabilizer with the actuator; the actuator may be turned to screw the microshunt into a hole in the cornea; and the actuator may be removed from the suction stabilizer, breaking the vacuum seal and leaving the microshunt inserted in the cornea.
CORNEAL LENTICULE EXTRACTION TOOL
Improved corneal lenticule extraction tools which integrate defined angles, tip features, and the use of vacuum into the tool to aid in the removal of the lenticule. The tool has a body and a tip each with an internal air channel. The tip has a straight portion and a curved portion at a distal end, with one or more orifices disposed on the curved portion. The body either has a mechanism for generating a vacuum in the internal air channel, such as a resilient diaphragm, or is connected to an external vacuum source. Use of tip features and angles helps the surgeon find tissue edges during tissue removal. The use of vacuum aids to draw the tissue to the tool and to hold the tissue by the tool. The improved tools improve speed of extraction as well as completeness of extraction so that no tissue is left behind.

Eye marker tip
The present invention provides an eye marker tip that includes a base, one or more marking wings, and a marking element attached to a marking wing and configured to deliver ink (or another indicator) to a surface of an eye. Embodiments may include a hollow or translucent post and light channel, or a base having a fixation button, to form a central light shape visible to a patient. Embodiments may include either or both of a magnifying lens and a parabolic light deflector, to form circles of light that may be used in connection with a central light shape to properly align the eye marker tip with a patient's eye.
Ophthalmic incisional procedure instrument and method
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.
Ophthalmic knife and methods of use
The present invention relates to an ophthalmic knife and methods of its use for treatment of various conditions including eye diseases, such as glaucoma, using minimally invasive surgical techniques. The invention relates to a multi-blade device for cutting the tissues within the eye, for example, a trabecular meshwork (TM).
Apparatus and method for securing ocular tissue
An ocular fixation device includes a body configured to be placed on an eye. The ocular fixation device also includes multiple twist picks configured to be turned to secure the body to the eye and to release the body from the eye. The body includes connection points on which a surgical tool is mountable on the body.
