[Effect of the culture technic on results following corneal preservation]

Organ culture of human donor material extends post mortem storage times up to 4 weeks. If dextrane is omitted from the medium, as in the authors' current technique, a stromal swelling occurs which can be reserved preoperatively. The authors also report on their experience with organ culture of donor material in a culture medium containing dextrane. Short-term incubation of donor tissue in culture medium at 32 degrees C containing dextrane may be possible as an alternative to the MK technique, in which the donor tissue is kept at 4 degrees C. All methods have specific advantages and disadvantages, not only in laboratory handling but also in the postoperative development of the graft.
