BACKGROUND: Corneal endothelial cell (CEC) disorders, such as Fuchs's endothelial corneal dystrophy, induce abnormal corneal hydration and result in corneal haziness and vision loss known as bullous keratopathy. We investigated whether injection of cultured human CECs supplemented with a rho-associated protein kinase (ROCK) inhibitor into the anterior chamber could increase CEC density. METHODS: We performed an uncontrolled, single-group study involving 11 persons who had received a diagnosis of bullous keratopathy and had no detectable CECs...

Transplantation of in vitro expanded human corneal endothelial precursors (HCEP) cells using a nanocomposite (D25-NC) gel sheet as supporting material in bovine's cornea has been earlier reported. Herein we report the transplantation of HCEP cells derived from a cadaver donor cornea to three patients using the NC gel sheet. In three patients with bullous keratopathy, one after cataract surgery, one after trauma and another in the corneal graft, earlier performed for congenital corneal dystrophy, not amenable to medical management HCEP cells isolated from a human cadaver donor cornea in vitro expanded using a thermoreversible gelation polymer (TGP) for 26 days were divided into three equal portions and 1...
