Aim:
To evaluate the effect of the corneal retrieval method on three outcome domains: donor consent rate, tissue quality and microbial contamination.
Methods:
A systematic literature review was conducted using the Scopus, PubMed and Web of Science databases employing predefined search terms pertinent to corneal retrieval methods, consent rates, tissue quality and microbial contamination. Studies relevant to corneal donation and consent rates as well as reports comparing in situ corneal excision with whole-globe enucleation that evaluated at least one of the three primary outcome domains were included. This study adhered to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines.
Results:
12 out of 91 studies met the inclusion criteria. In situ corneal excision is associated with higher rates of consent from the family members of the deceased. Corneas harvested via in situ excision were of comparable tissue quality to those obtained from enucleation. Additionally, contamination rates were similar.
Conclusions:
In situ excision of corneal tissue may provide a potential advantage in donor acceptance, while offering comparable tissue quality and microbial safety.
