The study " Autologous cultured corneal epithelium (CECA) for the treatment of unilateral corneal lesions associated with limbal stem cell deficiency" is the first clinical trial of this product manufactured at the LOEX laboratory. The culture of corneal epithelium strives to produce a reconstructed tissue with the therapeutical aim of treatment of unilateral limbal stem cell deficiency (only one eye is affected by the limbal stem cell deficiency). The study is a phase I/phase II study with the goal to evaluate safety and efficacy of the CECA graft for the treatment of human patients suffering from limbal stem cell deficiency.
