About Nasal Photodisinfection

Ondine's nasal photodisinfection is a patented technology using a proprietary photosensitiser (non-antibiotic, light-activated solution) to destroy pathogens. The photodisinfection treatment is carried out by a trained healthcare professional, and is an easy to use, painless, two-step process. The photosensitiser is applied to each nostril using a nasal swab, followed by illumination of the area with a specific wavelength of laser light for less than five minutes. The light activates the photosensitiser, causing an oxidative burst that is lethal to all types of pathogens. A key benefit of this approach, unlike with antibiotics, is that pathogens do not develop resistance to the therapy.

Nasal decolonisation with antibiotics is already standard practice in many hospitals prior to surgery, as pathogens in a patient's nasal cavities are a major cause of surgical site infections (SSIs). However, there is a growing need to reduce antibiotic use and find non-antibiotic methods of nasal decolonisation as resistance rates have been reported as high as 81%².

Ondine's nasal photodisinfection system has a CE mark and is approved in Canada and several other countries under the name Steriwave™. It has been used in Canada for over ten years, with no serious adverse events reported. In the US, it is currently undergoing clinical trials for regulatory approval.
