ⓘ Corneal button

A corneal button is a replacement cornea to be transplanted in the place of a damaged or diseased cornea normally approximately 8.5–9.0mm in diameter. It is used in a corneal transplantation procedure whereby the whole, or part, of a cornea is replaced. The donor tissue can now be held for days to even weeks of the donor’s death and is normally a small, rounded shape. The main use of the corneal button is during procedures where the entirety of the cornea needs to be replaced, also known as penetrating keratoplasty.
