Penetrating Keratoplasty (PK)

The cornea is the crystal clear window in the front of the eye.

If a cornea is no longer able to adequately accomplish one or more its functions (transparency, focused imaging, stability), the only available help is the tranplantation of a clear human cornea. A corneal transplantation can be performed full thickness or partial thickness (lamellar).

PK is a full-thickness transplant procedure, in which a trephine of an appropriate diameter is used to make a full-thickness resection of the patient’s cornea, followed by placement of a full-thickness donor corneal graft. Interrupted and/or running sutures are placed in radial fashion in the cornea. Later, the sutures could be removed at 1 year postoperatively.
