Currently there’s a shortage of donor corneas for those that need a transplant.  But a new procedure to help restore vision for two different corneal diseases may also address this supply problem.

Two specific diseases, keratoconus and Fuch’s dystrophy, affect different layers of the the cornea.  After the part of the cornea needed to treat keratoconus is removed from the donor tissue, the exact cells required to treat Fuch’s dystrophy remain intact.

By scheduling two patients for surgery on the same day, it would be possible to use one cornea for two patients, thus cutting in half the number of donor corneas needed.
