Scleral prosthesis for treating presbyopia and other eye disorders and related devices and methods
A scleral prosthesis includes an elongated body configured to be implanted into scleral tissue of an eye. The elongated body includes (i) opposing first and second free ends and (ii) multiple first portions that form the first end of the body and part of a remainder of the body between the first and second ends. The first and second ends are wider than the remainder of the body. The first portions are separated by empty space such that the first portions meet at a point between the first and second ends and are not connected to each other between that point and the first end. The first end projects beyond one or more sides of the remainder of the body and angles back towards the second end. The second end projects beyond the one or more sides of the remainder of the body and angles back towards the first end.
CORNEAL ENDOTHELIAL TISSUE TRANSPLANTATION SYSTEM
The present disclosure relates to a corneal endothelial tissue transplantation system for easily and precisely moving corneal endothelial tissue inserted into an anterior chamber of an eyeball. To this end, the corneal endothelial tissue transplantation system according to an embodiment of the present disclosure includes a tissue carrier to which cultured corneal endothelial tissue is attached and which is inserted into an anterior chamber of an eyeball, a magnetic field generation module including at least one magnetic field generator which generates a magnetic field for moving the tissue carrier, and a support plate which supports the magnetic field generator, and a user input module which receives an input signal for controlling the magnetic field generator from a user.
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.
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 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.
Scleral prosthesis for treating presbyopia and other eye disorders and related devices and methods
A scleral prosthesis includes an elongated body and an insert. The body includes (i) opposing first and second free ends and (ii) multiple first portions that form the first end and part of a remainder of the body between the ends. The first portions are separated along at least about half of a total length of the body by empty space such that the first portions meet at a point between the ends and are not connected to each other between that point and the first end. The ends are wider than the remainder. The insert is configured to be placed between the first portions and to substantially fill the empty space. The first portions are biased so that they maintain separation from one another without external interference but are configured to be pushed towards each other in order to reduce a width of the first end. The insert, when placed between the first portions, keeps the first portions separated and prevents the first portions from being pushed together and reducing the width of the first end.
CORNEAL IMPLANTS AND METHODS OF MANUFACTURING
Corneal implants that have an implant body comprising manufactured corneal tissue. Methods of manufacturing corneal implant that include manufacturing a volume of corneal tissue. Corneal implants that have an implant body made from cornea tissue removed from a living subject.
Scleral prosthesis for treating presbyopia and other eye disorders and related devices and methods
A scleral prosthesis includes an elongated body configured to be implanted into scleral tissue of an eye. The body includes (i) opposing first and second free ends and (ii) a pair of first portions that form the first end and part of a remainder of the body between the ends. The first portions are separated along at least about half of a total length of the body by empty space such that the first portions meet at a point between the ends and are not connected to each other between that point and the first end. The ends are wider than the remainder. The scleral prosthesis also includes an insert configured to be placed between the first portions and to substantially fill the empty space. The insert, prior to insertion, includes one or more slots. The first portions include one or more ridges configured to engage with the one or more slots of the insert.
Method for prevention of rejection and sever encapsulation of a supportive or functioning implant
A method of preventing rejection of an implant in the eye, includes forming a flap in the cornea of the eye, inserting an implant under the flap, cross linking corneal tissue surrounding an implant to make the corneal tissue surrounding an implant less vulnerable to enzymatic degradation, inserting polymeric material under the corneal flap so as to overlie corneal tissue, compressing a layer of the cornea from outside using a lens having a predetermined curvature to correct refractive error of the cornea, and cross linking corneal tissue that the polymeric material overlies.
OCULAR IMPLANT DELIVERY SYSTEM AND METHOD
A method and system for deploying an ocular implant into Schlemm's canal of an eye. The method includes the steps of inserting a distal end of a cannula through a cornea of the eye and into an anterior chamber of the eye, the cannula having a distal opening extending from the distal end and through a side wall, a curved distal portion and a curved intermediate portion; placing the distal opening of the cannula into fluid communication with Schlemm's canal; advancing the ocular implant distally through the cannula with a delivery tool engaged with the ocular implant, a proximal portion of the ocular implant engaging the delivery tool proximal to a distal portion of the delivery tool; and disengaging the ocular implant and the delivery tool when the proximal portion of the ocular implant reaches the cannula distal opening.
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.
