Endothelial corneal transplantation is a surgical technique for treatment of posterior corneal diseases. Mechanical microkeratome dissection to prepare tissue results in thinner, more symmetric grafts with less endothelial cell loss and improved outcomes. Dissections can be performed at the eye bank prior to corneal transplantation surgery.

Marginal grafts, such as fatty livers, grafts from older donors, or livers retrieved after cardiac death (DCD) tolerate conventional, cold static storage only poorly. We developed a novel model of subnormothermic ex vivo liver perfusion for preservation, assessment, and repair of marginal liver grafts prior to transplantation.

We describe use of full-field optical coherence microscopy as a method for high quality assessment of corneal donor stroma. This protocol can be used to identify features indicative of health or disease, and is aimed at improving the screening and selection of donor tissues, and hence the results of keratoplasty.

FAQs
Interpretation depends on the pattern of abnormalities seen in the graft and anterior eye. Stromal edema, keratic precipitates, inflammatory cells, epithelial defects, and reduced endothelial health may signal a complication, but their combined appearance helps clinicians consider whether host immune activity or microbial invasion is more likely. This distinction supports appropriate management and closer follow-up.
These findings provide different clues about graft status. Stromal edema indicates swelling within the corneal tissue, epithelial defects show disruption of the surface layer, and keratic precipitates are deposits associated with inflammation. Examining them together, rather than treating any single sign as decisive, helps separate expected postoperative changes from complications affecting graft clarity and function.
Endothelial health is important because changes in this cell layer can affect the graft’s ability to remain clear. Assessment therefore includes looking for alterations in endothelial status alongside stromal and epithelial findings. Monitoring these changes helps clinicians evaluate graft performance, recognize deterioration, and understand factors that may influence long-term graft survival after keratoplasty.
Slit-lamp microscopy allows detailed examination of the graft and anterior eye, including surface defects, edema, inflammatory cells, and keratic precipitates. Related imaging methods provide additional ways to evaluate graft structure or endothelial health. Using these approaches together gives a more complete assessment than relying on a single observation, supporting clearer clinical interpretation and research documentation.
A practical assessment begins with systematic examination of the transplanted cornea and anterior eye. The clinician evaluates graft clarity and function, then checks for stromal edema, epithelial defects, keratic precipitates, inflammatory cells, and changes in endothelial health. Slit-lamp microscopy and related imaging can document these findings, which are then compared with expected postoperative changes and possible complications.
The assessment is useful during postoperative follow-up whenever clinicians need to determine whether the graft remains clear and functional. Repeated evaluation can identify changes that suggest immune-mediated rejection, infection, or altered endothelial health. Timely recognition supports clinical decision-making, guides follow-up intensity, and contributes to better understanding of outcomes after corneal transplantation.
In transplant immunology, recorded graft findings help researchers study host immune responses and their relationship to graft survival. In ocular infection research, the same observations help characterize changes associated with microbial invasion and distinguish them from postoperative findings. Standardized examination with microscopy and imaging therefore connects clinical observations with investigations of rejection and infection.
