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