Bullous keratopathy is a condition where corneal endothelial cells, which do not normally proliferate in vivo, are extensively impaired by trauma, disease, surgery or the like and do not longer maintain the transparency of the cornea, leading to edema and turbidity. Kyoto Prefectural University of Medicine and Doshisha University jointly expanded corneal endothelial cells derived from donors and injected them into the anterior chamber of patients with keratopathy. 11 cases of a clinical study now confirmed effectiveness and safety of this treatment.
