  • Publication number: 20240366840
    Abstract: A technique can consistently achieve thicknesses of ?50 ?m for corneal tissue for Descemet stripping automated endothelial keratoplasty (DSAEK). Grafts with thicknesses of ?50 ?m are also known as nanothin DSAEK (NT-DSAEK) grafts. Evidence shows that using thinner DSAEK grafts, particularly NT-DSAEK grafts, can significantly improve visual outcomes. According to an example embodiment, a method for producing a corneal graft includes drying a donor cornea to cause a pre-cut thickness of the donor cornea to decrease. The method includes, concurrently with drying the donor cornea, determining pre-cut thickness measurements for the donor cornea. The method includes, in response to the pre-cut thickness measurements indicating the pre-cut thickness of the donor cornea has decreased to a predetermined value, cutting the donor cornea to a post-cut thickness of ?100 ?m, or more particularly ?50 ?m, to produce a corneal graft.

  • Publication number: 20240189094
    Abstract: A device for manipulating an implant includes a handle coupled to a guide extending from the handle to a distal end. The device includes an engagement mechanism disposed at the distal end of the guide and configured to engage an implant. The device includes a first actuator disposed on the handle and coupled to the engagement mechanism. The first actuator causes the engagement mechanism to engage the implant. The device includes an air chamber disposed in an interior chamber of the handle and configured to hold air. The device includes a lumen coupled to the air chamber and extending along the guide to the distal end. The lumen includes an air channel extending through the lumen. The device includes a second actuator disposed on the handle. The second actuator causes the air chamber to deliver the air, via the air channel, to the distal end.
