Testimonial from a Vetrolight And Vetrolaser customer:

 

"My 11 year old German-Lab mix "Shira" had hip pain her whole life.  But she was still able to do everything.  We live on a farm where we raise Quarter horses.  Shira thought she was a Bordser Collie and was just as agile as my two younger dogs.  The vet took some x-rays and showed me the problem—severe degeneration of both hip sockets.  Surgery wasn't an option.  It was way too expensive and the vet said it may not even work, so he put her on Rimadyl plus pain killers.  They worked fine for a while until the side effects become too much--kidney problems, bleeding ulcers.  I couldn't stand to watch Shira suffer, but I didn't want to put her down.  A friend of mine, who owns a cold laser, said I could borrow it for a few days to see if it worked on Shira.  Boy, did it ever! Within the first week of treating her hips and back, she was jumping around again, like a pup!  I also use an LED (Vetrolight) to control her pain every day.   My friend wanted her laser and LED back so I bought my own.  Best thing I have!  It's been almost a year since I started Shira on light therapy and she's still pain free.  I don't know what I would do without my Vetrolight and Vetrolaser.   Both are very affordable.  The same therapy at the vet would cost me $80 a visit, plus I would have to load Shira into the van each time.  Now I can treat Shira as often as I want for pennies, and I can do it at home."

FAQ


What conditions are treated with light therapy?
 
Therapeutic applications which have shown promising results based on studies include: Arthritis, Acupuncture Points (Smoking Cessation/Addictions), Back Pain, Enhances Lymphatic Drainage, Releases Tight Muscles, Soft tissue injuries, including sprains and strains, tendonitis and haematomas Carpal Tunnel Syndrome, Chronic Pain Maxillofacial Disorders, Nerve Regeneration, Neuropathy, Musculoskeletal Pain, Myofascial Pain, Tendonitis, Sports Injuries, Growth factor response within cells, and tissue as a result of increased ATP and protein synthesis.
 
What Is The Difference Between The Vetrolaser And Vetrolight?

The Vetrolaser is a laser, meaning it is coherent light.  This means all of the light photons travel in a straight line.  The Vetrolight is a group of LEDs (Light Emitting Diodes) which is non-coherent light.  The photons from an LED do not travel in a straight line.  Lasers penetrate deeper into the tissues than LEDs.

What Is The Clinical Difference Between A Cold Laser And A Therapeutic LED?

Cold lasers penetrate deeper than LEDs.  Cold lasers, while very safe to use, should not be used more than once per day per spot.  This is because of something called the Inhibition Effect which means the skin can become resistant to the light which can lead to diminished results.  LEDs are not known to cause this effect and can be used several times per day over the same spot. Note:  With a cold laser, you can treat multiple spots around the same area during one treatment session, but not more than one time per day for any one of these spots.  A 'spot' in this case means a spot the size of our laser/LED head, which is about 1.5 inches in diameter.

Do I Need To Buy Both A Cold Laser And Therapeutic LED To Get Complete Results?

Not necessarily.  It all depends on your clinical goals.  A cold laser is for deep healing as well as pain control. A therapeutic LED is mostly for continual pain control that you can use on your pet throughout the day without their skin becoming desensitized to the light (inhibition effect).  Many of our customers are only want to provide regular pain control for their pet which is why some only buy the Vetrolight.  Note: Therapeutic LEDs, like the Vetrolight, are also used to treat skin conditions.  

LEDs Are Everywhere. Is A Regular LED Flashlight Just As Effective For Pain And Healing?

LEDs are indeed everywhere.  You can find them in regular flashlights and in your car's dashboard.  But those are very low powered LEDs, some as low as 1.5 mW.  The low powered LEDs would not be effective for pain and healing. The Vetrolight has a total power of 500mW.  Plus, the Vetrolight has red and infrared LEDs.  These wavelengths are preferred by veterinarians who use light therapy in their practice.

Can High Powered LEDs Pose An Eye Hazard Like Lasers?

Yes, higher powered LEDs can pose an eye hazard. Even though LEs are not coherent light like lasers, they must treated as if they are lasers.  High powered lasers are very bright. Never stare directly at the beam.  Never reflect an LED on any surface, such as metal and other reflective materials, that can reflect back in your face or an animal's face.  Always make sure your pet's eyes are covered if the LED light is anywhere near their face.  The proper safety goggles are highly recommened.  We sell those on our site.  Even the darkest sunglasses or welding glasses will not protect against LED or laser light.  You must wear safety goggles specifically made for the laser or LED wavelengths you are using.

Note: If you are using a red-beam from a laser or LED, you should only use safety goggles that are made for that wavelength. The same goes for the infrared spectrum. Only use safety goggles that are made for the exact infrared wavelength you’re using. The Vetrolaser’s 808nm diode beams are barely visible but can still hurt your eyes if you look directly at them. In fact, infrared light can be even more dangerous to your eyes than visible red beams since the barely visible beams do not initiate the protective ’blink reflex’ as the red ones do, so you don’t know to look away. In other words, never at any time should you look directly into any laser beam. And never have any laser pointed at your eyes.  The Vetrolight LED also has 8 infrared (780nm) diodes which are just as hazardous to the eyes as lasers.  So again, make sure any LED or laser you are using is pointing down, away from anyone's or any animal's eyes.  And wear the right protective safety goggles.

What Is Low Level Laser Therapy?


Low Level Laser Therapy is a form of phototherapy or light therapy. This involves the application of low power light (red and near infrared light) to injuries or wounds to improve soft tissue healing and relieve both acute and chronic pain. It is also known as cold laser, soft laser or low intensity laser. Low level laser therapy aims to biostimulate. Because of the low power nature of low level laser therapy the effects are biochemical and not thermal and cannot cause heating and thereby damage to living tissue. The therapy is precise and accurate; and offers safe and effective treatment for a wide variety of conditions. The energy range of low level laser light lies between 1 and 500 mW (milliwatts), while for surgical lasers the energy range lies between 3000 and 10000 mW.

The Vetrolaser is a cluster head infrared laser featuring three 808nm diodes. All packages come with a separate single diode red laser (650nm/5mW). The 808nm infrared diodes penetrate up to 5cm (two inches) below the skin to treat deeper tissues such as tendons, deep wounds (proud flesh) muscles, and joints. The single red 650 m laser penetrates 1cm below the skin to treat superficial skin lesions, acupuncture points, and fungal infections of the foot (anti-microbial effect). Total output of the all three diodes is 300mW. 

How Does Light Therapy Heal?

Three effects are widely accepted in the literature.
* Reduction of Inflamation
* Analgesia
* Antibacterial/Antiviral


How Does It Work?


Low-level lasers supply energy to the body in the form of non-thermal photons of light. Light is transmitted through the skin's layers (the dermis, epidermis and the subcutaneous tissue or tissue fat under the skin) at all wavelengths in the visible range. However, light waves in the near infrared ranges like the Vetrolaser, penetrate the deepest of all light waves in the visible spectrum. When low level laser light waves penetrate deeply into the skin, they optimize the immune responses of our blood. This has both anti-inflammatory and immunosuppressive effects. It is a scientific fact that light transmitted to the blood in this way has positive effective throughout the whole body, supplying vital oxygen and energy to every cell.


What IS Low Level Laser Light?


Low-level laser light is compressed light of a wavelength from the cold, red part of the spectrum of electromagnetic radiation. It is different from natural light in that it is one precise color; it is coherent (it travels in a straight line), monochromatic (a single wavelength) and polarized (it concentrates its beam in a defined location or spot). These properties allow laser light to penetrate the surface of the skin with no heating effect, no damage to the skin and no known side effects. Rather, laser light directs biostimulative light energy to the body's cells which the cells then convert into chemical energy to promote natural healing and pain relief. It is NOT harmful.
 
What about LEDs?  Are Lasers Better?
 
LEDs (Light Emitting Diodes) are a very popular and effective forms of equine therapy and are used to treat the same conditions as the cold laser. In a nutshell, LEDs are a non-coherent source of light (scattered beam) as compared to the laser which is a coherent light source (focused beam). Clinical studies have shown that a focused beam penetrates much deeper into the tissues. The main advantage therapeutic LEDs have over lasers is that LEDs can be used regularly throughout the day over the same tissue without causing the "inhibition effect."  Using a cold laser too often over the same spot can cause the inhibition effect which means the tissues can become desensitized (resistant) to the laser light which can lead to diminished results.  Note: Always consult with a licensed veterinarian before treating your pet for any condition.

What Conditions Should Not Be Treated With Light Therapy?


A quick search of light therapy literature will tell you that it is advisable not to treat cancer and tumors with a laser or LED.  Therapeutic LEDs and cold lasers stimulate the production of energy within the cell, thus speeding up the cellular processes.  They can potentially do this for unhealthy tissue as well. This is precisely why you should ALWAYS consult with a licensed veterinarian before using ANY treatment device on your animal.

What About The Cost Of Therapeutic LEDs And Cold Lasers?

Buying hight quality and effective light therapy can be very expensive.  But it doesn't have to be.  Most cold lasers are way too expensive for the average horse owner or solo practitioner to buy. LEDs are usually less expensive than cold lasers since they're cheaper to manufacture. Most high quality therapeutic LEDs cost over a $1,000.00. Most cold lasers cost well over $6,000.00. Some are as high as $20,000.00!
The Vetrolight and Vetrolaser are real bargains. Our company does not employ sales people or have distributors.  If a company has distributors, they have to raise the price of the product in order to keep the distributors happy.  We are a very small company with only two full time employees, or in our case, two co-owners.  We keep our overhead low and pass the savings onto our customers.

 
Tell Me About The History Of Laser Therapy
 
The word "laser" is an acronym for Light Amplification by the Stimulated Emission of Radiation. Lasers do NOT emit X-RAYS and do NOT present the dangers of X-RAYS. The theory was first described by Albert Einstein (1879-1955) who paved the way for the development of the therapeutic laser.

The first low-level therapeutic laser was developed in 1962. By the end of the 1960's, Endre Mester in Hungary was reporting an improved healing of wounds through low-level laser radiation. Since then, scientists and doctors around the world have been using laser light to treat conditions that can affect all age groups.
 
High Power VS Low Power Medical Lasers


There are two types of medical laser: high power and low power. High power lasers are used to cut through tissue. Low-level lasers, on the other hand, are used to stimulate tissue repair through a process of bio-stimulation. Almost any diode frequency (green, red, infrared) can become a high power laser if you have enough power (wattage) behind it. For example, if you have 50 watts of power running a red laser you can bore a hole in the skin. Cold lasers use only milliwatts, small parts of a watt, and does not burn the skin. Burning a hole in the skin with a high power laser should not be confused with safe cold laser tissue penetration.
 
How Do You Use The Laser For Therapy?  Is It Difficult?

Treatment is simple and painless. It is similar to holding a flashlight close to the skin and shining the light on it. There is no sensation of pain, nor is there an increase in temperature from the laser. Treatment times vary based upon the size of the area to be treated, and the output power of the laser. Most treatments take 5-10 minutes for several areas (about 2 minutes per spot). Treating acupuncture points takes only 30 seconds per spot.
 
Are There Any Negative Effects From LLLT?


In all the years that low level lasers have been tested in research and clinical applications, no adverse side effects or negative impacts have been reported. This is why the U.S. Food and Drug Administration (FDA) classifies lasers and LEDs as “Non-Significant Risk” devices, requiring a minimum of safety precautions.

As mentioned earlier, the major precaution is discouraging direct viewing of the laser beam. Care should be exercised not to stare into the laser or LED beam or to point it at the eyes. The use of real laser/LED safety glasses is recommended. You should also take steps to shield animal’s eyes from the laser light.


Remember, the Vetrolaser and Vetrolight are intended for animal use only. Generally, cold lasers and LEDs for any use (human or animal) should not be used on women who are pregnant and on or near the thyroid or individuals with thyroid conditions. Cold laser therapy should not be used on cancerous lesions.
Cold laser and LED therapy is considered much safer than other therapies such as ultra-sound, and electrical muscle stimulation, which are used to treat some of the same conditions. Ultra-sound therapy can burn the tissues during treatment and requires the practitioner to use a messy conductivity gel before treating—and in some cases, shaving off the hair before treating. Electrical muscle stimulation could be uncomfortable to the animal and does not promote increased cellular activity.


Can You Guarantee The Effectiveness Of LLLT Or LED Therapy?


While clinical results are promising, no health care device or effect from that device can be guaranteed. The manufacturer and seller of the Vetrolaser/Vetrolight encourages the buyer/user to always consult with a licensed physician or veterinarian before using or buying this product. Make sure the subject being treated was carefully examined by a licensed veterinarian. The common danger in using this product is using it on a person or animal who has a serious medical condition that should be treated by a properly licensed veterinarian. Again, a medical evaluation is always recommended before using or buying this device.
 
How Long Have Cold Lasers Been Used For Equine And Canine Therapy?
 
Cold lasers have been used by veterinarians in Europe on both animals and humans since around 1970. Andre Mester, a Hungarian researcher, reported good results with wound healing on rats in 1968. And veterinarians have been using therapeutic lasers in the U.S. since the early 70’s. In fact, the FDA has approved some cold laser brands for use on human conditions such as carpal tunnel syndrome. Similar devices like the Vetrolaser do not require the same FDA approval since it is only sold and intended for animal/veterinary use only.
 
What Are Some Of The Other Healing Benefits Of Light Therapy?
 
For decades, researchers knew of the healing benefits of everyday, non-coherent light such as sunlight. In small doses, sunlight helps heal skin lesions. Of course if you overexpose yourself to the sun your skin will burn. What if there was a way of safely getting light to deeper tissues? Wouldn’t it help heal those tissues? That is the purpose of cold laser therapy. The coherent, concentrated light emitted from the Vetrolaser’s three infrared diodes safely penetrates up to 2 inches below the skin to help stimulate cellular activity to promote rapid deep tissue healing. This also explains why you shouldn’t use cold laser therapy over cancerous lesions; it also speeds up those cells.
1.    Wound healing is greatly improved by cold laser therapy. This includes even non-healing wounds like Proud Flesh in horses. This is probably due to the increased level of collagen brought about by cold laser treatment. Connective tissue is primarily composed of collagen which is thought to be the most important component in wound healing.
2.    An increase in circulation by widening of the blood vessels. This is important. When you’re treating a stubborn wound, for example, one of the first signs of healing is vascularization of the area—meaning you’ll see tiny blood vessel formation. Once you see this, the healing process is well under way.
3.    Decreased swelling/edema due to lymphatic drainage.
4.    Coherent laser light stimulates the production of body’s own natural pain relieving chemicals such as increased endorphin and enkephalin production.
Cold laser therapy is considered safe with very few contraindications. You should never look directly at the laser light and should wear protective eyewear such as real laser safety glasses built for the specific wavelengths you're using. UV or even the darkest welding safety glasses will NOT protect for laser light.  You should even shield the animal’s eyes from the light. For reasons that are not clear, you should avoid using cold laser therapy on animals who are pregnant. Also avoid using cold laser therapy on cancerous lesions.
 
What Are The Five Effects Of Coherent (Cold Laser Light) and Non-Coherent (LED Light) On The Body Tissues?
 
There are basically five effects cold laser light has on living tissues as concerns therapeutic value.
1.    Speeding Up Tissue Repair: Just like the sun is responsible for photosynthesis (which is the conversion of light energy into chemical energy), the light used in cold laser therapy acts to increase energy to the cells by aiding in the synthesis of ATP (Adenosine Triphosphate). Increased energy to the cells means increased cellular activity for all of the cell’s components that rely on this energy. Speeding up tissue repair also means less scar tissue formation. Scar tissue is a cheaper grade of tissue than never injured tissue. This is particularly important in tendons where they attach to muscles higher up in the leg where there are skeletal muscles. A scarred tendon has less elasticity than normal tendons.
2.    Faster Collagen Formation: Much of an animal’s body tissue is composed of the protein known as collagen. Increased collagen production is necessary for rapid tissue repair, and as mentioned above, to decrease scar tissue formation. This is especially apparent where you see a gooey residue formation around wounds.
3.    Increased Production Of natural Body Painkillers: Endorphins (endomorphines) are endogenous opiod biochemical compounds. They are peptides produced by the pituitary gland and the hypothalamus in vertebrates, and they resemble opiates in their abilities to produce analgesia and a send of well-being. In other words, they might work as "natural pain killers. The term endorphin rush has been adopted in popular speech to refer to feelings of exhilaration brought on by pain or danger, supposedly due to the influence of endorphins, although this term does not occur in the medical literature.
4.    Increased Lymphatic Drainage: Studies have shown that cold laser therapy can dramatically increase the size of the lymphatic ducts thus facilitating protein waste removal. This is especially important in the lower legs of a horse where circulation is limited.
5.    Increased Vascularization: This means increased blood flow to the tissues because of increased capillary formation. That’s the best positive sign you notice when treating a wound. This happens to deeper tissues as well—the ones you can’t see such as muscles and tendons. But when you see blood vessel formation over a wound you know the tissue is starting to heal. Again, first and foremost, never take any chances with healing.
The use of a cold laser does not take the place of veterinary care. Before attempting to treat any condition on any animal, consult with a licensed veterinarian first and take their advice over anything you see here. The user of the cold laser (Vetrolaser) assumes full responsibility for their actions in its use in any way. The sellers or manufacturers of the Vetrolaser assume no responsibility for the actions of others who use this device.

 


How long will the rechargable battery last? 

The battery is good for several hundred hours of use. When it eventually wears out you can buy a new one from Vetrolaser. The cost of a new battery is about $15 post paid.
