Human corneal endothelial cell transplantation with nanocomposite gel sheet preserves corneal stability in post-corneal transplant bullous keratopathy: a 16-year follow-up.

Post-corneal transplantation endothelial decompensation and subsequent bullous keratopathy often result in unfavorable clinical outcomes regardless of the treatment strategy employed. In this report, we present the outcomes of a patient managed with in vitro expanded human corneal endothelial cell (HCEC) transplantation facilitated by a nanocomposite gel (NC gel) sheet over 16 years. A 40-year-old male patient who presented with signs of graft failure after penetrating keratoplasty underwent HCEC transplantation.

A novel human donor cornea preservation cocktail incorporating a thermo-reversible gelation polymer (TGP), enhancing the corneal endothelial cell density maintenance and explant culture of corneal limbal cells.

Purpose: McCarey-Kaufman's (MK) medium and Optisol-GS medium are the most commonly employed media for human donor corneal preservation. In this study, we evaluated the preservation efficacy of discarded human donor corneas using a Thermo-reversible gelation polymer (TGP) added to these two media.

Methods: Thirteen human corneal buttons collected from deceased donors, which were otherwise discarded due to low endothelial cell density (ECD) were used.

Human corneal endothelial cell transplantation using nanocomposite gel sheet in bullous keratopathy.

Transplantation of 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 expanded using a thermoreversible gelation polymer (TGP) for 26 days were divided into three equal portions and 1.
