Yu Qiang Soh, Jodhbir S Mehta
PURPOSE: Peters anomaly is the most common cause of congenital corneal opacities. Although conservative management is often ineffective except in mild cases, surgical intervention in the form of penetrating keratoplasty is fraught with unpredictability and often has unacceptable postoperative outcomes. As such, there is a need to explore alternative surgical interventions that may possibly improve the postoperative visual prognosis in these patients. In this report, we present a case of type 1 Peters anomaly treated by selective endothelial removal without corneal tissue transplantation...

PURPOSE: Fuchs endothelial corneal dystrophy (FECD) is an acquired corneal endotheliopathy and is one of the most common indications for corneal transplantation surgery worldwide. Endothelial keratoplasty (EK) is the most popular form of corneal transplantation for FECD. In standard EK surgery, the patient's corneal endothelium and basement membrane [ie, Descemet membrane (DM)] are first removed, followed by transplantation of donor tissue that comprises allogenic corneal endothelial cells, DM, and corneal stroma of variable thickness...

Fuchs' endothelial dystrophy (FED) is characterized by corneal endothelial dysfunction and guttate excrescences on the posterior corneal surface, and is the leading indication for corneal transplantation in developed countries. In severe cases, keratoplasty is considered as the gold standard of treatment. However, there have been significant developments in our understanding of FED over the past decade. Attempts have been made to treat this disease with regenerative therapy techniques such as primary descemetorhexis without an endothelial graft or with a tissue-engineering approach...
