Influence of endothelial cell count of donor's cornea on endothelial cell loss.

In an experimental study porcine corneas were trephined using different trephining procedures. For every series of trephinations, the initial cell count of the donor cornea was found to play a role in the resulting damage induced by the cutting procedure. Pretreatment of corneas and modifications of trephining conditions did not change the negative correlations between cell count and damage due to trephining.
