Frequently Asked Question - FAQ
Am I a good candidate for CLT?
CLT has some contraindications, these include:
- Tumors and cancer (especially skin cancer)
- Benign tumors with possibility of converting to malignant tumors
- First three months of pregnancy
- Light sensitive autoimmune disorders Ex. Lupus
- Severe organ damage
There can be an interaction with certain medications and the laser. It is therefore important to consult a physician prior to cold laser therapy if you are taking these types of medications:
Steroids, NSAID’s, Anti-coagulants, Beta/Calcium blockers, Plenosol and local anesthetics such as Procainamide. A physician should be consulted and a note from that physician is to be brought to the laser treatment.
Why cold laser?
Laser therapy is non-invasive with no risk of infection (because no needles are being inserted). Some patients claim to feel a tingling sensation when the laser is being held over an area, however most people are unaware of any sensation during the treatment.
How many treatments?
Treatment protocols vary from patient to patient and are tailored to each individual patient’s needs. If patients are coming in for an acute injury more sessions are needed closer in succession. Conversely, patients with chronic issues are asked to come in less frequently but for a longer period. To maximize the effectiveness of treatments, 2 sessions a week is strongly recommended for 3 to 4 weeks depending on severity of condition - all treatment protocols will be discussed in the initial appointment. Healing an inflamed or problematic area can take time and is all part of the recovery process. The body needs time to heal and adjust to the treatments, therefore the more diligent you are about coming consistently, the faster the healing will take place. You should expect to book in for a minimum of 8-10 treatments to experience optimal results for most conditions.
Are there any side effects to CLT?
Patients may feel a little bit tired or more lethargic temporarily after treatment. Fatigue is the most common symptom after a session because the body releases natural pain killers (endorphins) after the treatment that put the body into a state of relaxation. It is vital that patients take it easy after a session and not overexert themselves to allow for the proper healing and recovery. Other side effects may include: headache or light-headedness.
Can CLT cause cancer?
No, CLT cannot cause cancer. Light energy used in the visible and infrared light spectrum (as used in CLT) are shown not to cause mutational effects or cancer. The reason being, visible and infrared wavelengths are too large to penetrate a cell molecularly and cause mutation.
Difference between hot laser and cold laser?
‘Hot’ or ‘High Level’ Laser Therapy is a more well-known use of laser therapy. HLLT is used for laser hair removal, laser tattoo removal and most dermatological procedures. It is referred to as a hot laser because the individual can feel heat or thermal energy during treatment, rendering the experience painful. A laser must produce 0.5W or 500 mW of power to be considered ‘hot’. CLT on the other hand, does not create thermal energy rendering it painless. A cold laser uses power below or equal to 0.2W/200 mW.
Can the laser be dangerous?
A Class 3B laser – used in CLT requires a warning sign on the door during times of operation. The maximum power output for this type of laser is less than 500 mW. Diffuse reflections of the laser beam are not hazardous, however if the beam is viewed directly it can cause damage to the eye. It is therefore imperative to wear safety eye glasses at all times for both patient and practitioner when near the laser.
