The device emits low dose 265 nanometre (nm) ultraviolet C light at a targeted area.
In a 2022 in vitro / ex vivo study to evaluate the therapeutic potential of 265nm UVC for infectious keratitis1, UVC was found to inhibit all tested bacteria and fungi, including mixed culture and strains linked to antibiotic resistance.
In the study, no evidence of infection was found from 4 hours onwards, ulcers responded significantly in under 24 hours, and at the end point, those treated with UVC performed as as well as those treated with ciprofloxacin.
Photon Therapeutics says that in simple cases, one five-second treatment will suffice, but more complex cases can be re-treated after 24 hours.
Currently, there are two main barriers to the successful treatment of eye infections in dogs.
The first is the difficulty diagnosing the infection and identifying the right antimicrobial to use, highlighted by a 2017 study: Bacterial Isolates from Canine External Ocular Disease and their Antimicrobial Sensitivities 2.
The second is whether the owner is able or willing to administer a topical treatment.
Here the evidence suggests that even when treatment is possible, people do not comply with clinical advice anything like as much as they claim.
Photon Therapeutics points to what it says is the nearest study there is, in which carers of young children with uveitis did not give the correct treatment in 75% of cases3.
If the device is as effective as claimed, then both these issues simply evaporate.
PhotonUVC costs £4,995.

PhotonUVC Vet is a non-contact treatment which emits low dose ultraviolet C light at a targeted area.
Photon Therapeutics says the device kills bacteria, viruses, fungi and other infecting organisms while being safe to host tissues.
Other claimed benefits of the device are that it avoids client compliance issues associated with eye-drops, it eliminates the need for antibiotic eye drops, and it is very simple to learn how to use.
The device costs £4,995.
To explain more about The PhotonUVC Vet, Dr. Simon Dean. MBChB, MSc, FRANZCO, FBCLA Chief Scientific Officer at Photon Therapeutics, and Dr. Mark Leddy BVSc, MBA, CEO, will be delivering a CPD presentation at the Exhibitor Showcase Theatre 3: "5 Amazing Seconds – A New Transformative Treatment for Corneal Infections", on Thursday 14th November at 3pm.
There is also a launch event reception at the stand from 16.15 to 18.15 on Thursday 14 November.
