A new scleral suction trephine for retrieval of corneoscleral donor tissue.
BACKGROUND
Removal of donor corneo-scleral shell from a cadaver, leaving the remainder of the eye in place, has become a popular technique. Manual removal can result in excessive trauma to the corneal endothelium or an uneven scleral rim.


METHODS
We describe a new technique for corneal retrieval using a sceral suction trephine.


RESULTS
The scleral suction trephine was cut evenly in our eyebank study. There was no additional trauma to the endothelium and the scleral rim was regular.


CONCLUSIONS
Suction trephination of the sclera in retrieval of corneal donor tissue appears to be safe and effective.
