Abstract. Purpose:To report the state of bacterial contamination of donor cornea obtained by a portable electric trephining and the clinical course after keratoplasty. Cases and Method:This study was made on 46 donor eyes obtained from the Nagasaki Eye Bank during 34 months through 2010. Bacterial culture was made from the preservation media and scrapings of rim of donor eye after removal of cornea using a portable electric trephining. Results:Microorganisms were cultured in 5 out of 46 specimens(10.9%)of scrapings and in 3 specimens(6.5%)of preservation media. They were all gram-positive cocci including Staphylococcus aureus(MRSA). No patient in the present series developed endophthalmitis after keratoplasty. There was no difference in the clinical course between patients with and without bacterial contamination. Conclusion:Use of electric corneal trephining may induce bacterial contamination of donor eyes. Caution is needed regarding the preservation media or cleansing fluid for gram-positive cocci.
