About Low Level Laser

How does LLL work?
There have been numerous scientific studies and are many research articles that discuss different aspects of Low Laser Light Therapy (LLLT), each with their own unique perspective, however the simple answer is through photonic absorption, laser light energy converts into chemical energy which initiates a cascade of events at a cellular level.

  • LLLT promotes healing in many conditions because it penetrates the skin, increases the ATP and activates enzymes in the targeted cells.
  • Growth factor response within the cells and tissue as a result of increased ATP and protein synthesis.
  • Improved cell proliferation.
  • Pain relief as a result of increased endorphin release.
  • Strengthening the immune system response via increasing levels of lymphocyte activity.

What is a TRUE Laser? [ Back to Top]
The Erchonia Laser is a TRUE LASER, fully compliant to the definitions set forth by those great men of science such as Bose and Einstein who predicted LASER in 1924 and the contemporary physicists Schawlow and Townes who brought LASER into the modern age. LASER is an acronym for Light Amplification by Stimulated Emission of Radiation. Light created in this way, is then culminated and directed into an intense beam of coherent light through the use of cathode and anode reflecting components in order to produce a single stable frequency. According to Webster's Dictionary, Lasers are coherent or marked by logical consistency. The Erchonia laser meets all the scientifically defined attributes of a laser and is therefore classified as a TRUE laser. We assure and maintain this classification, through our unique and patented process, which produces the emission of coherent light, generated at a precise and stable frequency, and in a focused direction.

What is the difference between a LASER and (LED) Light Emitting Diode?
Here are many light emitting products on the market today, claiming to be lasers that do not meet all scientifically defined attributes.  For example, products that use Light Emitting Diodes or LEDs as they are more commonly know, do in fact produce light, however the light is not intense, producing very little energy and are non-coherent, similar to light produced by common household light bulbs.  Non-coherent or non-culminated light is the result of photons moving in random directions at random times, generating random frequencies.  The most common use of LEDs is in electronic equipment, such as cell phones and VCRs, to inform the users that the item is ON.  LEDs are cheap and easy to reproduce.  Obviously, these devices are NOT lasers.  This misconception is in large part a by-product of marketing.  Some sales professionals use the word “laser” in order to describe a process such as in “laser pointers” which refers more to mankind’s collective imaginations than scientific comprehension.

What is low-level laser? [ Back to Top]
Unlike high power lasers that use heat and destroy tissue, low energy lasers affect the cellular energy of the underlying tissue. Hot lasers have a thermal effect and have an output of 1MW or above. Cold (or) Low Level Lasers do not have a thermal effect on tissue, lasers that stimulate biological function have an output below 10mw- milli-watts (ten- one thousands of a watt).

What it the difference between hot and cold laser?
Surgical lasers are the most common types of lasers in the medical field today. They are used to destroy, cut, and cauterize tissue. These are referred to as “Hot” lasers for obvious reasons. Hot lasers have a thermal effect and have an output of (1-watt) or above. Lasers with an output below (1-watt) are referred to as “low level” lasers, because they do not have a thermal effect on tissue, The lasers that stimulate biological function have an output below (10-millliWatts), ten/one thousands of a watt.

What is 3LT™ - Low Level Laser Therapy? [ Back to Top]
Low Level Laser Therapy (3LT™) refers to the modality of applying a "low" energy or "low level" laser to tissue that stimulates cellular processes and thereby enhancing biochemical reactions. For example, studies show that LLLT increases ATP production in the mitochondria of the cell. Since more energy is now available, the cell may utilize this fuel to function or operate more efficiently.

How does it work? [ Back to Top]
Many theories exist as to the mechanism of action for Low Level Laser Therapy(3LT™) but simply put, photonic energy is absorbed by the photo acceptor sites on the cell membrane which trigger a secondary messenger to initiate a cascade of intracellular signals that initiate, inhibit or accelerate biological processes such as wound healing, inflammation, or pain management.

What conditions can be treated? [ Back to Top]
Low Level Laser Therapy(3LT™) has been successfully used to treat many conditions such as acute and chronic pain reduction, repetitive use disorders like carpal tunnel syndrome, soft tissue strains and sprains, inflammation reduction, enhanced tissue wound healing, and cell regeneration.

Are there any side effects? [ Back to Top]
There are over 1500 published studies and not one of them mentions any negative side effects of semi-conductor diode lasers at the 5mW range like the Erchonia 3LT™ Lasers. Low Level Lasers are safe, non-toxic and non-invasive, there has not been a recorded side effect in over 1700 publications. There are some necessary common sense precautions that need to be considered, such as avoiding pointing the laser beam directly into the eye and maintaining it there, which could prove to be damaging to the eye.

What makes one laser different from another? [ Back to Top]
A laser can differ in its wavelength, power source or whether it is a continuous or pulsed wave form. The first lasers were used to cut, cauterize or ablate tissue and were classified as "hot' lasers. "Cold", "Low Energy" or "Low Level" lasers are used to enhance metabolic activity at the cellular level through non-thermal reactions.

What is wavelength? And do the different wavelengths matter? [ Back to Top]
Light is measured in wavelengths and is expressed in units of nanometers (nm). Different wavelengths have different energy levels and can have various effects on tissue. For example, the Erchonia 3LT™ Laser is 635 nanometers, which is found within the "red" spectrum of visible light (400-800 nm) and has anabolic tissue effects, whereas, radiation that has a wavelength shorter than 320 nm (ultraviolet (UV), gamma rays, x-rays) has ionizing effects on cells and can be harmful even in small doses.

Do you need FDA market clearance to sell these devices? [ Back to Top]
Erchonia Medical Lasers made history on January 17, 2002 by being the first Low Level Laser manufacturer to be given marketing clearance as Adjunctive Use in Pain Therapy for the treatment of chronic neck and shoulder pain. Although Low Level Lasers typically fall into the "non-significant" risk category, there are many lasers that have been used in the Veterinarian market that are being sold illegally for human use.
