Autologous Serum Eye Drops for Dry Eye Relief

Dry eye syndrome (DES) is a chronic lack of wetness in the eye caused by insufficient tears or poor tear quality. Dry eye syndrome can lead to irritation and if left untreated, can damage corneas. Autologous serum eye drops are most efficient and effective solution for intransigent cases of dry eye. Serum tears are a long-term treatment option, and it may take several weeks for patients to experience relief from the symptoms of their dry eye.

Autologous blood serum eye drops are made from patient’s own blood, and naturally contain essential components that are known to accelerate healing and improve lubrication of the surface of the eye. Eye drops made from a person’s own blood are better than artificial tears for relieving signs and symptoms of severe dry eyes. Plasma Tears is the leading provider of autologous serum eye drops more commonly known as serum tears, because we offer a quick, convenient and affordable way to obtain serum tears.

Our natural tears are composed of key components not found in artificial tear products, such as epidermal growth factor (EGF), fibronectin, and vitamin A, which support the proliferation, maturation, migration, and differentiation of corneal and conjunctival epithelia.

Serum contains IgG, lysozymes and complement, which have bacteriostatic properties. If these factors are low or missing, there is increased risk of persistent epithelial defects, blurred vision, infection, and scarring.
Serum is derived from whole blood after the blood is donated by the patient (autologous serum). Using a variety of methods of blood collection, storage, centrifugation, filtration, and dilution, we are able to formulate serum tears in which the serum components closely mimic our own natural tears.

Autologous serum has been used for ocular surface disease since the mid 1980s with a track record for a variety of different ocular surface conditions

Most clinical studies on autologous serum confirm that serum eye drop therapy is effective in corneal healing and reducing ocular symptoms. When conventional therapy has not met expectations for moderate to advanced dry eye patients, serum tears may make the difference.

You can expect to receive 12 5mL bottles (5 to 6mL fill) of ASEDs. Each bottle should last for 10 to 12 days, and approximately 2-3 months depending on the dosing regimen.
