Autologous serum tears are customized eye drops created from a patient's own blood serum. Unlike artificial tears, serum tears contain many of the same growth factors, vitamins, proteins, and nutrients found in natural tears that are essential for maintaining a healthy ocular surface.
These specialized drops help nourish and heal the cornea, reduce symptoms of dry eye, and support regeneration of damaged corneal nerves. Autologous serum tears are frequently recommended for patients with moderate to severe dry eye disease, neurotrophic keratitis, Sjögren's syndrome, persistent corneal staining, or those recovering from ocular surgery. Because they are made from your own blood, they are highly biocompatible and provide a natural approach to improving comfort, vision, and long-term ocular surface health.
