Nonpreserved Human Amniotic Membrane Transplantation in Acute and Chronic Chemical Eye Injuries

Abstract

AMT with nonpreserved amniotic membrane promoted epithelial healing, reduced surface inflammation, increased patient comfort, and decreased the extent and severity of vascularization when used in patients with acute chemical burns. When used in limbal stem cell deficiency owing to past chemical burns, AMT alone or in combination with LAT aided in ocular surface reconstruction. Infectious, inflammatory, or toxic/allergic reactions were not encountered in any patient owing to the use of nonpreserved amniotic membrane. Further studies are required to establish the safety and efficacy of preserved and nonpreserved AMT in ocular surface reconstruction.
