Frequently Asked Questions |
|
Q: Are there any side effects? |
|
A: |
There are over 1500 published studies and not
one of them mentions any negative side effect of the semi-conductor
diode lasers at the 5mW range like the Erchonia laser. Low-level
lasers are safe, non-toxic and non-invasive. |
|
Q: What makes one laser different from another? |
|
A: |
A laser can differ in its wavelength,
power source, or whether it is a continuous or pulsed waveform.
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. |
|
Q: How long are the treatments? |
|
A: |
Treatment time can vary from seconds to minutes depending
on the condition. Research studies show that there may be
a dose dependent response, so it may be more effective to
treat at lower does at multiple intervals than to treat a
single time with a high dose. |
|
Q: What is the difference between Lasers and LEDs
(Light Emitting Diodes)? |
|
A: |
Lasers are monochromatic (single color
wavelength), collimated (non-divergent) and coherent (wavelengths
in-phase). In contrast,
LEDs are neither coherent nor collimated, and
generate a broader band of wavelengths (multiple). In addition,
a significant
difference between the two is the power output.
The peak power output of lasers is measured in watts, while
that of LEDs
is measured in milliwatts. Also, LEDs usually
have a 50% duty cycle, meaning that they are “on” 50% of the time
and “off” 50% of the time regardless of what frequency
(pulses per second) setting is used. |
|
Q: How long does a treatment last? |
|
A: |
It varies depending upon the condition. For instance, an
acute soft tissue injury or open wound may require multiple
short treatments initially then the interval between treatments
will lengthen as the condition improves.
