A novel technique to center the donor punch for descemet stripping endothelial keratoplasty.
OBJECTIVE
This report describes a method to improve the accuracy of centration of the donor trephination for Descemet stripping endothelial keratoplasty.


METHODS
Using trypan blue, the donor corneal cap is outlined. The donor punch is centered on the actual cap rim rather than on a centration mark made either by the surgeon or by the eye bank preparing the precut tissue.


RESULTS
Using the described technique, eccentric donor trephination was reduced from 7.7% to 2.4%.


CONCLUSIONS
We have described a method to improve the centration of donor trephination and reduce the incidence of eccentric donor punching.
