Recurrent Keratoconus

Posted on: October 1st, 2010 by G. D.

Patients with keratoconus who become contact lens intolerant or have significant corneal scarring may require a corneal transplant to regain visual function.  The success rate of a full thickness transplant (penetrating keratoplasty-PK) is approximately 90%.  However, patients who have had a PK have a life-long 10% risk of rejection and, in the case of keratoconus, may have recurrence of keratoconus years after the transplant.  The photo to the left shows a patient with recurrent keratoconus after a PK who now successfully wears a scleral contact lens.
