Omnigen® natural wound dressing

Information for patients

What is Omnigen?

Omnigen is manufactured from a naturally sourced material used to improve your body’s wound healing. Omnigen can be used on eye wounds caused by trauma, infection or disease. It is applied using a special bandage contact lens during an outpatient appointment or in surgery. It may be used as a graft that permanently supports the structure and re-growth of your natural tissue or as a temporary bandage that can be removed. 

You may be treated with Omnigen if damage has been caused to your eye by disease or trauma.

A key benefit of Omnigen is how easy it is to use, meaning it is a fast and effective option for your treatment. Certain wound types benefit considerably from Omnigen, sometimes allowing for surgery-free treatment.


Omnigen is approved for treatment on the National Health Service (NHS) and at certain private clinics. Your healthcare professional will have information on how to access Omnigen.


Key benefits of amniotic membrane treatment

Omnigen is approved for treatment on the National Health Service (NHS) and at certain private clinics. Your healthcare professional will have information on how to access Omnigen.

What is Omnigen?

Omnigen is a natural material derived from the amniotic sac that surrounds a baby in the womb. The amniotic membrane has natural wound healing properties, preventing problematic inflammation and supporting your body’s wound-healing process.

We source our amniotic sac from women who choose to give birth by elective caesarean section and have given full voluntary informed consent for their amniotic sac to be collected and used in the manufacture of Omnigen. Donors are screened to ensure they are healthy.

To create Omnigen the amniotic sac is delicately processed  under stringent regulations  to ensure it is safe to use.

NuVision follows the Joint United Kingdom Blood Transfusion and Tissue Transplant Services Professional advisory committee (JPAC UK) guidelines when consenting all donors.

Donation and safety testing

Women who donate their amniotic sac for the manufacture of Omnigen give voluntary informed consent for their amniotic sac to be used and receive no payment or benefit for doing so.

We screen potential donors’ medical history for information of infectious and autoimmune diseases and lifestyle choices that could increase the risk of contracting an infectious disease. Donors undergo blood tests for diseases including: 

  • HIV I & HIV II
  • Hepatitis B
  • Hepatitis C
  • HTLV-I
  • Syphilis
  • Cytomegalovirus

All of NuVision donors are tested negative for COVID-19,  at the point of consent.

Processing Omnigen

NuVision manufacture Omnigen by delicately processing and preserving the amniotic sac.

NuVision’s patented process is regulated and audited by the United Kingdom Human Tissue Authority (HTA) (Licence No. 22656). These regulations apply the following Acts of Parliament:

  • The Human Tissue Act 2004
  • The Human Tissue (Quality and Safety for Human Application) Regulations 2007
  • HTA Guide to Quality and Safety Assurance for Human Tissue and Cells for Patient Treatment, v3 Directions 001/2021  § (2021)

During processing the amniotic membrane undergoes thorough treatment to reduce transmission of potential infections, including treatment with antibiotics and antimycotics. As there are trace elements of these antibiotics and antimycotics in Omnigen, you should inform your clinician if you are allergic to any antibiotics/antimycotics (gentamycin, imipenem, polymyxin B, vancomycin, nystatin).

How does Omnigen work?

Omnigen promotes regeneration of tissue and wound healing.

The amniotic sac used to manufacture Omnigen surrounds, protects and nurtures the foetus during pregnancy. This is a complicated biological task, as the baby is nurtured while being protected from the mother’s immune system which could recognise the baby as a threat. 

The amniotic sac plays a key role in foetal development, producing essential proteins that facilitate normal growth and development of the foetus. These properties also have important function in wound healing and recovery:

  • Immuno-suppressive to reduce long term complications
  • Anti-fibrotic to stop excess tissue growth
  • Anti-angiogenic to prevent inappropriate development of blood vessels

Retention of amniotic membranes natural properties allow for its transplantation to promote the regeneration and recovery of healthy tissue.

How will my treatment with Omnigen be carried out?

Omnigen is thin, meaning you will barely notice it is there.

If you have an eye condition treated with Omnigen, it may be applied in surgery or using a special contact lens in an outpatient setting – read about OmniLenz  to find out more. Your healthcare professional will decide the best method of application for your eye wound.

Use of Omnigen to dress wounds may not require surgery or sutures, depending on the condition being treated. Omnigen can be an excellent option for conditions where rapid treat is required or when surgery is not immediately available.

Once your condition has healed, Omnigen will either naturally resorb or will be removed by your healthcare professional. This depends on the condition your condition and duration of treatment.

If you would like specific information around your treatment, please ask your clinician for guidance.

What makes Omnigen different?

Omnigen provides a natural aid to wound healing.

Tereo® preservation protects and retains the important structural, composition and biological healing properties of fresh amniotic membrane to aid ocular healing.

Omnigen can be stored dry on site and is ready to use immediately unlike other products derived from the amniotic sac. This reduces the time it takes for your wound to be treated and means Omnigen is available for use in emergency and unplanned routine settings. The faster wounds receive treatment with Omnigen the more likely they are to heal well.

As there is the option to apply Omnigen in an outpatient setting with OmniLenz, this treatment is very accessible for many different diseases.
