20220354633 · 2022-11-10 · ·

The present solution can temporarily impart the handling characteristics of corneal stroma to the otherwise very thin, flimsy, coiling, and fragile Descemet membrane endothelial keratoplasty (DMEK) tissue during its insertion into the anterior chamber and positioning in apposition against the cornea of the recipient eye. The device of the present solution can be configured in a number of ways. In a first configuration, a scaffold can be coupled with the endothelial side of the DMEK graft. In a second configuration, the scaffold can be coupled with the stromal side of the DMEK graft. In a third configuration, one or more scaffolds can be coupled with both the endothelial and stromal side of the DMEK graft.

A technique can consistently achieve thicknesses of ≤ 50 .Math.m for corneal tissue for for Descemet stripping automated endothelial keratoplasty (DSAEK). Grafts with thicknesses of ≤ 50 .Math.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 precut 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 .Math.m, or more particularly ≤ 50 .Math.m, to produce a corneal graft.
