Optimizing the Ocular Surface Prior to Cataract Surgery

March 5, 2019 updated by: Tissue Tech Inc.
Prospective study to evaluate the efficacy of using self-retained cryopreserved amniotic membrane after debridement in treating Epithelial Base Membrane Dystrophy (EBMD) to optimize the ocular surface integrity and intraocular lens calculation before cataract surgery.
