CORNEAL IMPLANT INSERTERS AND METHODS OF USE
Devices that are adapted to insert corneal implants onto corneal tissue. Methods of using the devices include inserting the corneal implant into a pocket created in the cornea. Methods of use also include inserting the corneal implant onto corneal tissue after a flap has been created in the cornea. The devices can be adapted to deliver fluid to an implant holding space to at least assist in the deployment of the implant from the holding space and onto corneal tissue.
Non-invasive refractive treatment using nanoparticles
Embodiments of this invention generally relate to systems and methods for optical treatment and more particularly to non-invasive refractive treatment method based on sub wavelength particle implantation. In an embodiment, a method for optical treatment identifies an optical aberration of an eye, determines a dopant delivery device configuration in response to the optical aberration of the eye, wherein the determined dopant delivery device is configured to impose a desired correction to the eye to mitigate the identified optical aberration of the eye by applying a doping pattern to the eye so as to locally change a refractive index of the eye.
Device for reversibly attaching an implant in an eye
The object of providing a device for reversibly attaching an implant to an eye, with which the implant can be attached in a simple way to the eye and can if necessary be detached or removed from the eye, is achieved according to the present invention by means of a device for attaching an implant by means of a pin that comprises a substantially elongated shaft, wherein the implant includes an implant film for contacting living tissue or nerves in the visual system of the eye and the implant film has an opening through which the shaft of the pin can be at least partially inserted, characterised in that the device includes a holding element that can be arranged on the shaft of the pin so that the holding element engages on the shaft of the pin and is fixed in an attachment position to the pin. By means of the device according to the invention the implant is on the one hand reliably attached, but can if necessary be detached from the retina by removing the holding element or retainer, wherein the pin anchored in the eye does not have to be removed at the same time, but can be re-used. Damage or injury to the tissue of the eye that would otherwise be associated with the removal of the pin can thereby also be avoided.
CORNEAL IMPLANT STORAGE AND DELIVERY DEVICES
Corneal implant applicator devices and methods of using. In some embodiments they include an implant applicator and an implant support, wherein the implant applicator and implant support are disposed relative to one another to form an implant nest that is adapted to house a corneal implant; wherein the applicator has a greater affinity for the corneal implant than the support.
Intracorneal lens
The present invention relates to an intracorneal lens (1), comprising a circular main body having a convex front surface and a convex rear surface, characterized in that the convex front surface has a single uniform radius of curvature (Rcv) and the concave rear surface has a radius of curvature (Rcci). The radius of curvature (Rcci) of the concave rear surface is greater than the average radius of the cornea by 0.1 mm to 2 mm, preferably 0.2 to 1.5 mm, in particular preferably 0.5 to 1 mm. The present invention further relates to a kit, comprising a storage unit (15) and a pre-load unit (P) inside the storage unit (15). The storage unit (15) is made of a watertight material and can be closed watertight by means of a plug (16). The pre-load unit (P) is fitted with the intracorneal lens according to the invention.

THERAPEUTIC INSTRUMENT
A therapeutic instrument (20), includes: a support member (25) having a tongue-shaped supporting portion (50) for supporting a sheet-like therapeutic agent; a nozzle member (23) having a cylindrical portion (30) in which the supporting portion (50) supporting the therapeutic agent can be housed, and having an opening (34) through which the supporting portion (50) can be loaded and unloaded in/from a tip of the cylindrical portion (30); a syringe unit (22) that acts a positive pressure in the cylindrical portion (30) for pushing-out the therapeutic agent housed in the cylindrical portion (30) together with the supporting portion (50) to outside the cylindrical portion (30) through the opening (34); and a water flow forming part including a plurality of protrusions (53) formed on a surface of the supporting portion (50) so as to form a water flow at a place where the supporting portion (50) and the therapeutic agent are faced each other, when a medical water is fed into the cylindrical portion (30) in a state in which the therapeutic agent is housed in the cylindrical portion together with the supporting portion (50).
CORNEAL PROSTHESIS AND METHOD OF PENETRATING KERATOPLASTY
A method of implanting a corneal prosthesis in an eye to interconnect host tissue with a corneal graft can include forming an opening in a host tissue of an eye. The method can also include forming a first passageway through the host tissue that extends annularly about an optic axis of the eye. The method can also include forming a second passageway through a corneal graft that extends annularly about an axis of the corneal graft that is substantially collinear with the optic axis of the eye when said corneal graft is positioned in the eye, the first passageway and the second passageway having the same diameter relative to the optic axis. The method can also include forming a gap in the host tissue that extends between a lateral side of the host tissue and the first passageway.
Incised Descemet's membrane and methods of making and using
This disclosure describes a Descemet's membrane endothelial keratoplasty (DMEK) graft prepared using paired incisions; compositions including the incised DMEK graft; an injector including the incised DMEK graft; a viewing chamber including the incised DMEK graft, methods of preparing the incised DMEK graft; and methods of using the DMEK graft, the compositions, the injectors, and the viewing chambers including to facilitate placement of DMEK grafts during cornea transplant surgery.
Implantation device for intrastromal prostheses
Implanting device for intrastromal prosthesis that introduces segment (ring) onto inside of intrastromal tunnel in a patient's cornea. Device includes a ring holder having clamp to support segment to be inserted and a cylinder base having hollow cylindrical shape and first and second cylinder ends.
