The present invention relates to a device for holding human or animal corneal tissue previously removed for photon treatment thereof with electromagnetic radiation, notable in that the holding device comprises: a stack of elements along a longitudinal axis (A-A′) of the device, said stack comprising: a first plate () that is transparent to the electromagnetic radiation, a peripheral seal () positioned on the first plate (), the peripheral seal () being intended to extend around the corneal tissue (), a second plate () that is transparent to the electromagnetic radiation on the peripheral seal (), an immobilizing system () for immobilizing the stack of elements and able to press the first and second plates () firmly against the corneal tissue in order to apply mechanical stress to the anterior and posterior faces of the corneal tissue.

Device for holding corneal tissue for photonic treatment thereof

A device for cutting human or animal tissue including a femtosecond laser that can emit a L.A.S.E.R. beam in the form of impulses. The device directs and focuses the beam onto or into the tissue for the cutting thereof. The device further includes and element to shape the L.A.S.E.R. beam, positioned in the trajectory of the beam, and to modulate the energy distribution of the L.A.S.E.R. beam in the focal plane thereof, corresponding to the cutting plane.

Device and method for cutting a cornea or crystalline lens

The invention relates to a medical device for preservation of corneal tissue () that has been obtained beforehand by sampling, the device comprising a base (), at least one side wall (), and means for receiving and blocking the corneal tissue (), characterized in that the device additionally comprises an applanation lid () for covering an opening of the device opposite the transparent base (), the applanation lid () comprising: a transparent window (), and a support () between the window () and the side wall (), the support () comprising means for moving the window () in translation with respect to the side wall () of the device.

Medical device for preservation of a corneal tissue, comprising an applanation lid, and optionally a trepanation lid

The invention relates to a medical device in the form of a cartridge () incorporating an assembly permitting the preservation of corneal tissue that has been obtained beforehand by sampling, the device comprising: a storage compartment () containing a preserving fluid, at least one input terminal () upstream from the storage compartment (), for injecting a compressed pressurizing gas, at least one control terminal () upstream from the storage compartment (), for injecting a compressed control gas, a pneumatically controlled switching system () downstream from the terminals (), said switching system () being controlled by the compressed control gas in order to permit or prohibit the circulation of the compressed pressurizing gas towards the storage compartment ().

Medical device in the form of a cartridge for preservation of a corneal specimen

A device for the storage of a corneal specimen has means for the reception and entrapment of a corneal specimen, connected to the means for the creation of a pressure gradient with overpressure on the endothelial side and to the preservation medium circulation means in the layouts that present the means for the reception and entrapment of the cornea specimen. The means for the reception and entrapment of the corneal specimen entrap the sclera ciliary zone surrounding the cornea in an airtight manner to delimit a separate endothelial chamber and epithelial chamber in which the preservation medium can circulate with an overpressure in the endothelial chamber; The intermediate component and the endothelial lid comprise inlet and outlet orifices for the preservation medium which are connected to the means for the circulation of the preservation medium and the creation of a pressure gradient between the endothelial chamber and the epithelial chamber with overpressure in the endothelial chamber.

Medical device intended for the long-term storage of a cornea, or for ex vivo experimentation on a human or animal cornea
