Normandy Catering prepared food for a reception in celebration of the completion of the Cornea Preservation Time Study at Eversight Ohio. The Cornea Preservation Time Study (CPTS) is a nationwide study with 36 participating clinical sites, including over 50 corneal surgeons, and 23 participating eye banks. It is the first of its kind to study whether endothelial keratoplasty (a corneal transplant surgery) using donor corneas preserved beyond 8 days may be as successful as a surgery using donor corneas preserved less than 8 days.
When a donor cornea is obtained, it is placed into a liquid in a special chamber and kept at a refrigerated temperature until surgery to preserve it in good condition. The Food and Drug Administration (FDA) has approved storage of the cornea in this liquid for up to 14 days before the transplant. However, it is unknown if the length of time the cornea is in this liquid before the transplant makes a difference. Overseas, the practice of using corneas past 7 days is quite common but this practice is not as common in the United States.
