Treating Chronic Wounds with Light Therapy

Light therapy has been shown to greatly enhance the natural wound healing process especially when used in conjunction with hyperbaric oxygen therapy.  Light therapy is non-invasive, painless, and has the ability to return patients to their pre-injury level of activity.

The lack of effective treatments can lead to significant patient complications including amputation and death, and potentially increase medical treatment costs and length of hospital stays. A break-through treatment, such as ours, can speed recovery, reduce hospital stays, save limbs and save lives.

Dosimetry

Patients are given one dose of light (more as needed to cover entire wound) every other or every 3rd day. Continue throughout healing process. 

Results of a Clinical Study on Light Therapy for Chronic Wound Healing

Venous ulcers, which usually develop on the medial distal leg, are very painful and can be difficult to treat. In a randomized placebo-controlled double-blind study, the hypothesis that that LED phototherapy combining 660-nm and 890-nm light would promote healing of venous ulcers that failed to respond to other forms of treatment was tested.

A randomized placebo-controlled double-blind study was used to compare a total of 20 patients divided with 32 chronic ulcers into three groups. In group 1 the ulcers were cleaned, dressed with 1% silver sulfadiazine (SDZ) cream, and treated with placebo phototherapy (<.03 J/cm(-3)) using a Dynatron Solaris 705 phototherapy research device. In group 2 the ulcers were treated similarly but received real phototherapy (3 J/cm(-2)) instead of placebo. In group 3 (controls), the ulcers were simply cleaned and dressed with SDZ without phototherapy. The ulcers were evaluated with digital photography and computer image analysis over 90 d or until full healing was attained.

Ulcers treated with phototherapy healed significantly faster than controls when compared at day 30 (p +/- 0.01), day 60 (p +/- 0.05), and day 90 (p +/- 0.001), and similarly healed faster than the placebo-treated ulcers at days 30 and 90 (p +/- 0.01), but not at day 60.

Phototherapy promotes healing of chronic venous ulcers, particularly large recalcitrant ulcers that do not respond to conventional treatment.
