• K-Sol is a widely used corneal preservation medium. It has an excellent record for corneal storage and no previous report of contamination. During September 1988, on five of our K-Sol-stored donor rims Propionibacterium acnes grew. Cultures of unopened K-Sol also yielded P acnes. This report reviews previous contaminations of corneal storage media and the special characteristics of P acnes that enabled it to survive precautions taken against infection. The detection of P acnes was not obvious, and we emphasize the need for appropriate culturing of all donors, both aerobically and anaerobically, and close scrutiny of delayed inflammation in postoperative patients.
