PUBLICATION EXCLUSIVE: Best practices for handling, preserving PDEK corneal tissue still being established
While DMEK strips only Descemet’s membrane and endothelium from recipient stroma, the proposed advantage of PDEK lies in the preservation of the pre-Descemet’s layer. The big bubble technique has enabled the eye bank community to obtain a graft that potentially combines the advantages of younger donor tissue with the better visual outcomes of DMEK. Other potential advantages of PDEK tissue include higher endothelial cell counts (secondary to younger donors), grafts more resilient to tearing (due to the slightly thicker nature of the graft), and theoretically similar rates of rejection as (Read more...)
