Pre- and postoperative slit lamp photographs of a patient with band keratopathy who underwent combined ethylene diamine tetraacetic acid chelation, phototherapeutic keratectomy, and permanent amniotic membrane transplantation. (A) Preoperatively, extensive calcium deposition with an irregular surface was detected in the central cornea. (B) Two weeks after surgery, the amniotic membrane was well attached to the cornea. (C) Six months after surgery, the corneal surface was smooth and stable with mild stromal opacity and neovascularization at the inferior cornea.
