These images show the post-operative appearance of 4 different patients after penetrating keratoplasty (PK), or full-thickness corneal transplantation.  PK grafts may be secured using interrupted sutures (A, B), running sutures (C), or a combination of both (D).  Sutures are usually removed during the post-operative period.  Grafts may remain clear for decades with proper care, as seen in this patient 30 years after the procedure with all sutures removed (E, F). Read the related article for more information regarding modern corneal transplantation techniques.
