Discrepancies in Endothelial Cell Density Values of Human Donor Corneas Resulting From Comparison Between Specular Microscopes and Endothelial Analysis Methods.

Purpose: The methods for specular microscopy evaluation across eye banks differ, which may result in variability in endothelial cell density (ECD) values that influence the surgeon's decision about donor tissue. A comparison of instruments and analysis methods is conducted in this study.

Methods: Specular images were captured from 97 donor corneas using both HAI and Konan specular microscopes.

Precut Post-Laser In Situ Keratomileusis / Photorefractive Keratectomy Donor Corneas for Use in Endothelial Keratoplasty: Potential Impact of Postcut Morphology on Visual Outcomes.

Purpose: To evaluate the accuracy, complication rates, cut quality, and degree of induced hyperopic shift of eye bank-prepared post-laser in situ keratomileusis (LASIK)/photorefractive keratectomy (PRK) donor corneas compared to those of non-post-LASIK/PRK donor corneas.

Methods: The cut accuracy and failure rates of all post-LASIK/PRK donor cornea tissue processed for use in Descemet stripping automated endothelial keratoplasty (DSAEK) from January 2012 through December 2016 were compared to control cornea donor tissue. Corneas were analyzed for regularity and morphology of cut using anterior segment optical coherence tomography images.
