“…These include optical clarity, support of epithelial migration and adhesion, solute permeability and stability to corneal proteases. Historically, biomaterials used in ocular surface reconstruction have included partial thickness epidermal grafts, 2 oral mucous membrane, 3 vaginal mucous membrane and fetal membrane, 4 rabbit peritoneum, 5 and amnion 6–10 . Veterinary use of biomaterials to reconstruct the ocular surface have included conjunctival grafts, 11 Gore‐tex, 12 split‐thickness dermal grafts, 13 equine pericardium, 14 peritoneum, 15 equine amniotic membrane, 16 and equine renal capsule 17 in dogs; porcine small intestinal submucosa in dogs, cats and horses; 1,18,19 and human amniotic membrane in rabbits 20 .…”
