What Makes MLS® Laser Different To Other Class 4 Lasers?
You may be considering adding laser to your practice and so have looked at a number of different devices. If so, you’ve probably come across class 3B lasers, class 4 lasers, hot lasers, cold lasers and everything in between. Lasers which promise you a fix for every indication you might see in your clinic and others which are more specific. How do you know which one is right for your practice? And what makes MLS® laser different to the rest?
Power
MLS® Laser is a class 4 or “high level” laser, meaning it delivers more than 0.5W peak power. Traditional class 3B (low level/cold lasers) deliver no more than 0.5W peak power. Higher power means shorter treatment times and quicker treatment benefits for your patients. MLS® offers 25W or 270W peak power options. Both of these provide significant and similar clinical benefits. The 270W unit has shorter treatment times and requires fewer treatment sessions overall to see a similar clinical result.
25W options:
Vet Blue
270W options:
M-Vet
The key difference between MLS® laser and other class 4 lasers is MLS®’s unique nanopulse technology which means MLS® is a NON-THERMAL laser and does not generate any significant heat build-up within the tissues. Read on to learn more about this.
Wavelength
Chromophores are elements in the body which can absorb light. Some key chromophores for laser treatments are water, haemoglobin, melanin and cytochrome c oxidase (CCO) – the wavelength used by a laser is what helps to determine which chromophore will absorb the light emitted. MLS® is different to lasers which are used for surgery. Surgical lasers tend to use 6000-10000nm and target absorption by water. MLS® uses wavelengths which target CCO (905nm and 808nm) and can help to reduce pain, inflammation and swelling and encourage a healing response in the body.
Both these wavelengths are delivered in a simultaneous and synchronised system, reducing treatment times and increasing treatment efficacy. No need to change settings or handpieces for different wavelength delivery!
The 905nm wavelength is delivered at 25W or 2700W peak power (depending on the device) giving it a strong analgesic effect. This wavelength features ASA’s unique nanopulse technology. This wavelength rapidly pulses on and off during treatments, allowing any thermal energy to dissipate and disperse evenly through the tissues meaning it is totally safe to use in both scan mode and point mode. Read on to learn more about these modes.
Point mode/scan mode
Most class 4 or high-power lasers require the laser to be kept moving continuously across the skin to avoid thermal injury (ie the build-up of heat in the tissues).
Due to its nanopulse technology, the MLS® laser can be used in ‘point mode’ which allows the head of the laser to be held in situ for a pre-set length of time. This is ideal for the treatment of focal areas of pain eg arthritic joints, dental extraction sites, trigger points, etc and for treating wound edges, tendons and ligaments. It ensures a standardised amount of energy is delivered to a very specific area and reduces time wasted moving the handset.
