The donor-recipient interface was identified as the area where a change in cell morphology and/or extracellular matrix was detected.
Corneal massage was performed to adjust the centered position of the donor graft and to eliminate residual fluid at the donor graft-recipient interface.
The donor-recipient interface haze, the characteristic gain in reflectance that may be observed at the border between the donor graft and the recipient cornea, was also evaluated by IVCM.
While we didn't find any influence of the graft central thickness on postoperative BCVA, our analysis indicated a inverse correlation between subepithelial and donor-recipient interface haze and visual outcome.
Graft thickness was measured by IVCM by assessing the distance from the endothelium to the change of reflectance that suggests the beginning of donor-recipient interface, then calculating the mean between the values obtained in each of the three scans performed by IVCM at each examination.
Also donor-recipient interface haze has been assumed to affect visual outcome after endothelial keratoplasty [ 13, 37, 38]; in contrast Espana et al [ 30] and Baratz et al [ 23] did not find a significant correlation between interface reflectivity and visual outcome.
In Descemet membrane endothelial keratoplasty (DMEK), lamellar splitting of the Descemet membrane (DM) may occur during stripping of host DM, leaving residual DM on the recipient's DMEK interface.
It also enables communication with recipients, providing the interface for tracking a courier with your delivery, estimating the time until delivery, and letting users contact the courier to handle odd pick-up situations.
After placement of the graft into the corneal recipient's bed and suturing, remaining interface fluid could be detected by intraoperative OCT in two out of four patients.
The compact lamellar bone offers a good surface for the insertion of the osteosynthesis screws, while the cancellous part of the graft provides a wider interface between donor and recipient bone, allowing early revascularization.
These germ cells and follicles were consistently observed in wild-type recipient ovaries close to the graft interface with aged transgenic donor ovary tissue, and the frequency of their detection was unaltered by TSA exposure prior to collection.
