How does Laser Treatment Work

How Does Laser Treatment Work?

Laser TreatmentLaser Treatment offers a directed pulse of heat to a specific area. They are particularly effective at treating fungal growths while leaving the healthy tissue intact. Not all lasers are the same however, and we will discuss the differences of each.

There are two main types of lasers, and they are either hot lasers, or cold lasers. Cold lasers function by simply shining a light on the area without heating the skin. This light bolsters the body’s immune system, and encourages it to fight the fungus on its own. Additionally, they speed up the regrowth of the nail following the procedure.

However, there is some contention on the effectiveness of cold lasers. Dr. Kavic MD, Medical Director of Body Beautiful Laser Medi-Spa posits that “only hot lasers work because it is the heat from the laser that destroys the fungus.”

Choosing a Laser Treatment

Cold and hot lasers have differences, and there are also variances in how long we apply the laser. Specifically, most FDA approved laser treatments deliver in short, rapid pulses. There are also long-pulse lasers that are approved and effective.

The latest innovation in laser technology— Q-switched lasers— are able to deliver rapid pulses of light in mere nanoseconds for effective treatment. Alternatively, cold-wave lasers utilize two longer wavelengths of laser light to fight off toenail fungus.

In the past there used to be carbon dioxide lasers, however we seldom find their use modern medicine as they are quite outdated.

Long Pulsed Laser

Laser TreatmentThe first long pulse laser the FDA approved was the PinPointe Foot Laser.The way the treatment works is by delivering ultra long pulses of energetic light to the area for thirty minutes. This allows for the light to deliver less heat to the affected area, but still retain the effectiveness of a traditional laser. Many podiatrists have reported successful treatments when using such technology, such as podiatrist Dr. Christina Teimouri DPM, an Associate at the American College of Foot & Ankle Surgeons.

There was a problem with its consistent procedure. While other laser treatments require little to no aftercare, long burst laser treatments such as PinPointe Laser require that the patient undergo strict aftercare measures, and according to Dr. T  few of the patients that they treat under her care follow through with the instructions given to them. Second generation technology has greatly improved both the time it takes to treat the area, and decreases the excess heat.

Q-Switched Lasers

“I have treated thousands of patients successfully with the Q-Switch Laser. We have found it to be highly effective in resolving all types of fungal toenail infections in addition to yeast and mold toenail infections.” says Dr. Teimouri. While treating these conditions with Q-Switch Laser is effective.

Another newer addition is the Q-Clear Compact Laser from Light Age, which belongs to the latest class of Q-switched lasers. The treatment takes 4-15 minutes and results are visible after only one session. Also in this class of lasers is the Lightpod Neo from Aerolase. One of the other modern laser techniques is Q-Clear Compact Laser from Light Age. This type of laser belongs to a class of lasers known as Q-switched lasers. The treatment lasts around 4-15 minutes with visible results after only one session of therapy. Another type of laser in this class is the Lightpod Neo from Aerolase. Dr. K. uses it in tandem with Pro-Nox, which is a pain-reducing nitrous oxide delivery system

Dr. K uses LightPod Neo in combination with Pro-Nox, a pain-reducing nitrous oxide system that ensures patient comfort during the treatment. “Usually 5-6 treatments are necessary and we perform them every two weeks.” he adds.

Heat Lasers

There are several options for heat based lasers, and one such option is the Cutera Genesis plus. This laser offers flexibility when dealing with thicker or thinner nails, and sessions last roughly 10-30 minutes.

Another heat laser available is the JOULE ClearSense, and touts a shorter session time of 10-20 minutes with immediate results.

Finally, CoolTouch VARIABreeze utilizes a coolant during the procedure, while also using a laser that adjusts to prevent overheating. The session lasts around 15-20 minutes.

Cold Lasers

Cold lasers offer some unique benefits to patients that may be preferable to the benefits of a heat laser. One such laser is the LunulaLaser that takes only 4 5-12 minute sessions. Yet it is able to treat the entire nail while remaining odor-free (something that heat lasers cannot claim to offer).

Another cold laser to consider is the Noveon NaiLaser. It is able to treat four toes in one session. However, sessions take about a half-hour, and can require up to four sessions for extreme cases.
