Penetrating Keratoplasty (PK)

Penetrating Keratoplasty (PK) is a full-thickness transplant, performed when the abnormality extends through all layers.  The diseased central cornea is cut from the patient's eye using a mini cookie-cutter device, called a trephine.  The new donor cornea graft is measured and cut with a trephine and sutured in place with approximately 16-20 stitches.  

The outpatient surgery usually takes 30-45 minutes. The eye is numb completely during the surgery and most patients are sedated ("twilight sleep") during the procedure. A patch and shield is placed on the eye and remains in place until the next day follow-up examination in the office.  Eye drops are used to prevent infection and rejection.  The transplant can take several months to heal and stabilize.  Sutures may be selectively removed after a few months.  All the sutures do not have to be removed.  Your doctor examines and decides which sutures should be reomved to allow the best healing, corneal contour, and vision outcome.  Most patients will need glasses, contacts, or rigid gas permeable contacts after a transplant.  Vision recovery can take up to 9-12 months.


Specific post-op instructions will be given at the time of surgical counseling and after surgery.  Risks are inherent to any surgical procedure.  Detailed risks, benefits and alternatives will be discussed thoroughly between each patient and the doctor at the time of consultation.


Each patient's eye is different. The description above may not apply to every individual situation. Your doctor will perform a full evaluation and discuss her findings thoroughly. A treatment regimen will be planned and re-evaluated throughout follow-up visits. Please contact your doctor if you feel you have dry eyes or if you have any concerns or questions regarding your ocular health.
