A 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. Ocular discomfort was not relieved with lubricant drops and a repeat EDTA chelation will be performed.
