Study to assess safety and efficacy of synthetic membrane used in limbal epithelial cell transplant instead of donor membrane in blindness caused by chemical burns

A proof of concept study to evaluate the clinical safety and efficacy of a Poly Lactide-co-Glycolic Acid (PLGA) biodegradable, synthetic carrier membrane, used to regenerate epithelium using autologous limbal tissue as a single step procedure in patients having total unilateral limbal stem cell deficiency (LSCD). - LVPEI-2012-11

No severe pathological and psychological conditions that might interfere with the patients participation in the study 7. Able to provide written informed consent prior to any study specific screening procedures with the understanding that the patient has the right to withdraw from the study at any time, for any reason without prejudice.

Exclusion criteria

Exclusion criteria: 1. Bilateral LSCD 2. LSCD due to autoimmune disorders and partial LSCD 3. Having other ongoing ocular pathologies and acute ocular inflammation 4.
