P08-A131 Comparison of sterile donor tomography in the eye bank and previous keratometric measurements during the donor's lifetime.

The front and back surface astigmatism as well as the central corneal thickness remained statistically unchanged after corneal excision and preservation in organ culture in comparison to measurement of the donor prior death. The statistically non-similar anterior and posterior radius of curvature between both methods must be seen in light of the known differing corneal topography between swept-source anterior segment optical coherence tomography and Scheimpflug imaging. These results suggest a merely minimal deformation caused by the storage and attachment of donor corneas to their holder in the cell culture flask for sterile donor tomography, causing a steeper anterior surface curvature but leaving the astigmatism still congruent with previous in situ conditions.
