How laser therapy helps
The use of LLLT for wound healing has been shown to be effective in modulating both the local and systemic responses involved in the complex tissue healing process. Depending on the wavelength, dose, and local condition, LLLT has been shown to have an anti-inflammatory effect, to reduce pain, and accelerate cell proliferation and consequently the healing process in soft tissue.
Influencing all three phases of wound healing: the inflammatory, proliferative and remodelling phases, photobiomodulation promotes ATP synthesis, induces cell proliferation, accelerates collagen synthesis, increases tensile strength and influences the concentration of prostaglandins thus reducing pain associated with inflammation.
For post-surgical healing, the cell proliferation, the promotion of angiogenesis and the proliferation and migration of keratinocytes enables a wound site to close more quickly and it is especially useful for treatment of immune-compromised patients with chronic non-healing wounds.
All Omega probes come with removable autoclavable tips or bezels to accommodate cross-infection avoidance policies and can be used in conjunction certain sterile barriers.
“After having months of treatment for various leg ulcers from my doctors and nurses, they were not responding. I was referred to Ashdown Clinic, where I received laser treatment. This was successful, and the ulcers were completely healed.”
Female patient in nursing / residential home with 23 years leg ulceration. Previously treated using Florozene and Alginate dressings.
Dose: 8 J/cm2 per treatment (2 minutes per point)
Wavelength(s): Multiple wavelengths
Pulsing: mixed low, medium and high frequencies
Probe: 46 Diode Cluster Probe
Frequency/intervals: Once every 2 weeks
Patient reported being pain-free relatively early on in treatment but complete healing of chronic leg ulceration took a total of 9 months (including a 4 month break due to unrelated illness). Quickly able to socialise, no pain and completely healed.
Some Relevant Research
Biostimulative effects of 809nm diode laser on cutaneous skin wounds
...The findings of the study show that tissue repair following laser irradiation of 809nm has been accelerated in terms of tissue morphology, strength and cellular content. These results seem to be consistent with the results of many researches previously published in literature and support the idea that LLLT has therapeutic effect on wound healing process.
Low-level laser therapy (LLLT) efficacy in post-operative wounds
...Clinical evaluation showed that the healing process of these postoperatively treated wounds has occurred and that the functional recovery of the patients...was faster than without treatment. Conclusion: LLLR with wavelength of 904 nm to stimulate postoperative aseptic wounds (early scar) is efficient in both cases of cutting plague.
Histological assessment of the effect of laser irradiation on skin wound healing in rats
...As compared to non-irradiated control wounds, laser stimulation shortened the inflammatory phase as well as accelerated the proliferative and maturation phase, and positively stimulated the regeneration of injured epidermis and the reparation of injured striated muscle. CONCLUSION: LLLT at 670 nm positively influences all phases of rat skin wound healing.
Influence of low level laser therapy on wound healing and its biological action upon myofibroblasts
...CONCLUSIONS: Laser therapy reduced the inflammatory reaction, induced increased collagen deposition and a greater proliferation of myofibroblasts in experimental cutaneous wounds.
Effects of level laser therapy on pain and scar formation after inguinal herniation surgery: a randomized controlled single-blind study.
...CONCLUSION: Infra-red LLLT (830 nm) applied after inguinal-hernia surgery was effective in preventing the formation of keloids. In addition, LLLT resulted in better scar appearance and quality 6 months post surgery.
Efficacy of LLLT in swelling and pain control after the extraction of lower impacted third molars
...CONCLUSIONS: This study demonstrates that LLLT is effective on postoperative pain and oedema accelerating healing time and reducing patients distress.
