A cornea transplant is an operation to remove all or part of a damaged cornea and replace it with healthy donor tissue. A cornea transplant is often referred to as keratoplasty or a corneal graft. It can be used to improve sight, relieve pain and treat severe infection or damage.
Penetrating keratoplasty (PKP), also referred to as a corneal transplant or corneal graft, is the surgical removal of a damaged or diseased portion of the cornea, followed by the implantation of healthy tissue from a donated human cornea, which is usually obtained from an eye bank.
Penetrating keratoplasty, or full thickness corneal transplantation, is the surgical procedure most commonly used in management of blinding corneal disease.

There are two types of endothelial keratoplasty. The first type, called Descemet stripping endothelial keratoplasty (DSEK), uses donor tissue to replace about one-third of the cornea. The second type, called Descemet membrane endothelial keratoplasty (DMEK), uses a much thinner layer of donor tissue.
Typically 16 sutures are placed, although in large corneal grafts or corneoscleral grafts, additional sutures may be necessary. Suture placement is usually performed to minimize the development of astigmatism, with every other suture being placed 180 degrees away from the previous suture.
DMEK is very similar to DSAEK, with the primary difference being that the donor tissue implanted does not include any stromal tissue, but is instead a pure replacement of endothelium. A DMEK graft, therefore, is much thinner than a DSAEK graft.

DSEK is intended to transplant a healthy endothelial cell layer that will pump the fluid out of the cornea. It's expected to restore corneal clarity and improve vision. This procedure corrects corneal endothelium failure, but is not able to correct corneal scarring, thinning or surface irregularity.
A transplant complication is only coded if the function of the transplanted organ is affected. Patients may still have some form of CKD even after transplant. Malignancy of a transplanted organ should be coded as a transplant complication followed by the code C80. 2, Malignant neoplasm associated with transplanted ...
