This trial aims to investigate the use of a cultured corneal epithelium graft from the unaffected eye of patients with Limbal Stem Cell Deficiency. The trial is being conducted at the Centre Hospitalier Universitaire de Québec, Quebec and proposes to recruit 15 patients between December 2012 and December 2017. Biopsies from the unaffected eye will be cultured and used as a stem cell corneal transplant in the affected eye. All participants will be monitored for complications following the procedure, and changes in clinical condition, including improvements in corneal opacity, vascularisation and integrity of the epithelial surface.
