79-year-old Caucasian woman presented to our clinic with
a complaint of gradually progressive foreign-body sensation and ocular surface irritation that had affected the left
eye for several months. She had a history of bilateral neovascular
age-related macular degeneration. In the left eye, she had pseudophakia, macular translocation in 1997, penetrating keratoplasty
in 1999 for the treatment of pseudophakic bullous keratopathy
and multiple Nd:YAG laser membranectomies to treat pupillary
membranes. She underwent an ethylene-diamine-tetra-acetic
acid (EDTA) chelation with superficial keratectomy in 2007 with a
gradual reaccumulation of calcium.
In our clinic, her BCVA was 20/250 in the right eye and
20/640 in the left. Her right eye had a 2+ nuclear sclerotic cataract and an otherwise unremarkable anterior segment. Her left
eye, as shown, had band keratopathy extending across the graft
and host cornea with intact epithelium. The graft was otherwise
clear and compact. She also had a posterior chamber lens with
open posterior capsule.
