What are Autologous Serum Eye Drops?

Autologous Serum Eye Drops, or ASED, are made by combining a patient’s own serum with sterile, preservative-free saline. The concept of using serum as an eye drop is based on the biochemical similarities between an individual’s serum and natural tears. This solution contains growth factors and vitamins that may help heal epithelial defects and relieve symptoms of severe dry eye.
