Abstract
Dyskeratosis congenita is a syndrome of bone marrow failure secondary to unstable telomeres. It is characterized by a range of mucocutaneous diseases. Due to premature telomere shortening, these patients have limbal stem cell deficiency leading to poor regeneration and maintenance of the cornea. Many of these patients will require hematopoietic stem cell transplant in their lifetime, which poses a significant risk for acute and chronic graft-versus-host disease with and without ocular manifestations. We advise against elective corneal refractive surgery in patients with dyskeratosis congenita due to the compounded and long-term risks of delayed healing secondary to limbal stem cell deficiency and ocular complications of graft-versus-host disease post-allogeneic hematopoietic stem cell transplant.
