About Vendaje Optic


which is processed using our proprietary BioRetain process.

This process creates a dehydrated human amniotic membrane

BioRetain®-the science of letting nature do its work

Six steps work together to preserve the natural integrity of amniotic tissue:

Minimally damaging

The membrane is submerged in an effective bactericidal, tuberculocidal, fungicidal and virucidal solution to eliminate pathogens

Manual hematopoietic

Blood and blood-producing components are removed by hand without scraping or scrubbing to preserve membrane structure

Cold isotonic

A series of washes in clean, low-temperature, pH-balanced solution with gentle stirring remove remaining debris while minimizing tissue and growth factor breakdown

Gentle and gradual

Slow drying of the membrane using physiological temperature preserves tissue structure and natural growth factors, preventing damage from freezing or high temperatures

Precise cutting die

Precise, manual placement of cutting dies helps ensure optimal tissue quality for each individual allograft

Low-dose E-beam terminal

Grafts are individually packed and terminally sterilized to an assurance level of 10-6 via electron beam*, avoiding harmful biproducts or excessive irradiation associated with other methods

*Our sterilization assurance level (SAL) is generally accepted for pharmacopeial sterilization procedures, with a probability of not more than one viable microorganism per one million sterilized items of the final product.

VENDAJE OPTIC consists of only the amnion layer of the placental membrane. This single layer of amnion measures between 20-50 microns thick, making VENDAJE OPTIC ideal for delicate ophthalmic applications.

VENDAJE OPTIC is intended for homologous use as a protective covering.

Properties of Dehydrated Human Amniotic Membrane

Helps prevent local contamination

Demonstrates antimicrobial properties

Helps prevent moisture loss

Provides a scaffold for tissue healing

Contains a range of growth factors

Contains anti-inflammatory cytokines

Amniotic tissue is a natural reservoir of growth factors, extracellular matrix (ECM) components, and anti-inflammatory cytokines which are known to support the body’s natural healing processes.

Amniotic tissue is a natural reservoir of growth factors, extracellular matrix (ECM) components, and anti-inflammatory cytokines which are known to support the body’s natural healing processes.




Placentally-derived human amniotic membrane (AM) is a potent source of pro-healing growth factors and anti-inflammatory cytokines and has successfully been used in regenerative medicine for over a century. Early users of AM for wounds and post-surgical applications noted how the membrane seemed to disappear and integrate with the patient’s own tissue without a host reaction. This apparent immune neutrality is a result of mechanisms that suppress and modulate the immune system.

The use of AM was initially limited due to storage challenges associated with use of the fresh tissue. Modern processing methods – including dehydration – have delivered options that have longer shelf lives, can be stored at ambient temperatures, and can be terminally sterilized. These advances also allow manufacturers to create thinner coverings that are suitable for delicate ophthalmic use.

Today, dehydrated human amniotic membrane (DHAM) continues to be widely used and studied as an ophthalmic covering across a range of topical applications.

Structure of the Amniotic Membrane
The amniotic membrane forms the innermost layer of the human placenta and acts as a protective barrier for the developing fetus.

Interestingly, the basement membranes of fresh AM and the conjunctiva of the eye share an identical distribution of components (laminin-1, laminin-5, fibronectin, and type VII collagen).

Natural Amniotic Components Retained in VENDAJE OPTIC

VENDAJE OPTIC allografts are prepared using our proprietary BioRetain® process, which was designed to help preserve the natural ECM components, anti-inflammatory cytokines, and endogenous growth factors within fresh tissue.

The following substances were isolated within VENDAJE allografts (n=6)*:

Anti-inflammatory cytokines:
– Interleukin (IL) 10

IL-10 helps suppress the pro-inflammatory milieu and modulate immunity through a variety of pathways.

– IL-1 receptor antagonist

This substance naturally inhibits pro-inflammatory effects of IL-1.

Extracellular matrix (ECM) components:
– Collagens I, III, IV, V, and VI
– Elastin
– Laminin
– Fibronectin

The ECM of amniotic membrane provides mechanical protection and functional support for cell attachment, proliferation, and migration.

Hyaluronic acid (HA):

HA suppresses the expression of TGF-β1, β2, and β3, as well as TGF-receptor expression, providing an anti-fibrogenic effect.

Growth factors:
– Epidermal growth factor (EGF)
– Vascular endothelial growth factor (VEGF)
– Basic fibroblast growth factor (bFGF)
– Keratinocyte growth factor (KGF)

* This is not a comprehensive list of the substances found within VENDAJE OPTIC.
