Donor Tissue Can Be Stored for 11 Days before Transplantation –Four Days Longer than Current Convention
November 10, 2017–New national research led by Jonathan Lass, MD of Case Western Reserve University School of Medicine and University Hospitals Cleveland Medical Center has found that corneal donor tissue can be safely stored for 11 days before transplantation surgery to correct eye problems in people with diseases of the cornea. This is four days longer than the current conventional maximum of seven days in the United States.
The findings are published in today’s issue of JAMA Ophthalmology
“Over the past 20 years, corneal transplant specialists have gotten comfortable only using corneas up to one week after they are stored. But our findings show they can safely use them up to 11 days after first being stored,” said Lass, Charles I Thomas Professor in the Department of Ophthalmology and Visual Sciences at Case Western Reserve School of Medicine, member of the University Hospitals Eye Institute, and lead investigator of the national Cornea Preservation Time Study, which produced the results. “This will help to meet the expected future demand for corneas in this country as well as in patients overseas today, who now receive as many as thirty percent of corneas donated by U.S. citizens.”
