What to Look For When Buying a Therapeutic Laser

Although all lasers biologically stimulate cell metabolism via a similar mechanism, that is where the similarities end. The bottom line when it comes to laser therapy it’s all about physics. In order to get penetration you need power. Every doctor knows in order to get deeper penetration with x-rays you need to increase the power output and time of exposure. Laser energy is just another form of energy on the electromagnetic spectrum just like x-rays and the key to greater laser energy delivery and penetration is the same principle and is based on the wavelength and power output of the laser and the time of laser exposure. Without sufficient power you will not penetrate and deliver the necessary therapeutic dosage. In order to get outcomes you need the proper dosage and dosage is a function of power output. Once you are in the infrared spectrum, 800nm to 1064 nm the key is power output and dosage.

As the doctor who received FDA clearance for the first class iv laser in 2003, I have found over the years as we increased power output and energy delivery we saw better and faster outcomes. Energy delivery is a function of power output and it doesn’t matter the brand of the laser as much as the power output and whether or not the laser is operating on a continuous basis or if it is pulsing or operating under a 50% duty cycle, which means the laser is only firing 50% of the time. When you treat a patient you are dosing them with therapeutic energy and the dose is directly related to the power output of the laser and the frequency it is on. Another important factor to look at is whether the laser operates under a single or dual wavelength mode. Laser penetration is based on an absorption curve for each wavelength, and the ability of each wavelength to penetrate is not additive. Dual wavelength lasers such as K-Laser or Litecure can only penetrate as deep the individual wavelength that penetrates the most. So what this means is for a 15 or 25 watt dual wavelength laser you need to cut the penetration ability in half. If the laser has a 50% duty cycle then the penetration is only 25% off the average power output of the wavelength with most powerful diode output. We have long known this and also proved that our single wavelength laser cannot only accelerate wound healing superficially, it can also penetrate to accomplish healing in deeper-seated pathologies such as disc herniations. There is no magical wavelength. Once you are in the infrared spectrum they all work well. The key to better outcomes is power and energy dosage. That is why we operate under a single wavelength of which we have over 13 years of clinical experience in both human and veterinary medicine.

Ultimately the more powerful lasers not only dose patients faster they penetrate deeper and ultimately lead to better and faster outcomes.

In summary as you search for a class iv laser our recommendation is to seek out a single wavelength laser which puts out the most energy over a given time period as well as the laser that offers continuous output operation for the given price point you are willing to spend. Realize that any money saved on a laser which can dose the same amount of energy by treating twice as long, is more than offset by your increased labor costs.

Patient testimonials using Class IV Laser Therapy

Patient: Joan C.
Age: 74
Diagnosis: Neuropathy – Extreme pain (feet);
Source: Letter to Dr. Bruce Coren, CEO

Dear Dr. Coren:
I spoke to you by phone some months ago when Dr. Dorfman used your laser in the healing of my neuropathy. It has been a miracle. Thank you for this laser. It has changed my life from a semi-invalid to a 74-year-old who is exercising and on the go 10 hours a day.
God Bless You,
Joan C.
Boca Raton, Florida

Patient: William J.
Age: 54
Diagnosis: Lateral Epicondylitis (Tennis Elbow)
Complaint: Extreme pain of the right elbow, unresponsive to rest, ice, and medication over the past 3 months.

I had contracted tennis elbow on the right arm. The severity was such that I started playing tennis with my left arm. Five laser treatments were administered over a period of fourteen days. After the first laser treatment there was an immediate and noteworthy reduction in pain accompanied by a moderate gain in functional ability. Thanks to the laser treatments, I was able to play high-level tennis with no pain whatsoever.

Patient: Lauren T.
Diagnosis: Ulmnar Nerve/Pain
Complaint: Scar Tissue/Pain Following Surgery

I had an ulmnar nerve release in 1995. A lot of scare tissue was removed. I was mostly pain free for 12 years. When the scare tissue grew back it was just as painful as right before surgery. I was miserable and tried many diiferent types of therapy sessions – perhaps 40 and the pain still persisted, and with just 4 laser treatments I’m back to full use, pain free! THANK YOU for creating this machine.

Patient: Richard M.
Age: 78
Diagnosis: Severe Arthritis of the left hip;
Prognosis: Told by doctor that hip replacement was only option;
Complaint: “Unbearable” left hip pain that does not decrease with medication. The pain also interferes with walking and wakes him up at night.

Within 15 minutes of the first treatment, the pain subsided dramatically. After twenty minutes, the treatment was over and I left the room feeling a great deal relieved. By the fourth visit, I was pleased to discover the pain relief lasted over the weekend into Monday.
