Cordless 2-channel LLLT System
(Auricular Application)
Efficacy -- lasers to the right position with sufficient dose

emLas-520 is developed to apply Low Level Laser Treatment (LLLT) in auricular regions for the achievement of "Laser Biostimulation" effect.

emLas-520 is patented and made using the combination of modern laser diode technology, innovative optics design and computerized digital control.

emLas-520 is clinically proven for treatments as a mono therapy or as a complementary treatment along with other therapies to treat:
Meniere's Disease
Hearing Loss
Hyperacusis: oversensitivity to sound
Sudden Deafness
Vertigo and Balance Disorder

How to select the right laser for you?
If you had audiometric test before:
Please review the test result and select the laser according to your frequency response of sound.
If you did NOT have audiometric test before:
The best way for treating inner diseases is to apply different lasers with different wavelengths to have the thorough biostimulation response for different depths of the inner ear. We strongly recommend the laser therapy with the emLas-520AC (INFRARED laser of 780nm + RED laser of 660nm).

It is normal for someone gets warm in the auricular laser therapy. It is the biostimulation of your body and you will feel the warmth.
You can begin with the shorter treatment time like 10 minutes then gradually increase it to maximum of 30 minutes.
Ten treatments are usually administered on either 10 consecutive days, or over a two week period. It is recommended to stop the treatment for 1 week after finishing phase-1 therapy.
Then phase-2 therapy can be continued with the same protocol.
It takes 1~3 months to see the effectiveness (after the treatment, it needs time for your body to repair yourself).
emLas-520 is applying ear tips and the laser beam is designed to be dispersion type, with the beam divergence angles in parallel and perpendicular, you can just put it on and move slightly- ideally applied for home therapy. There is no laser leakage if the laser modules are properly applied. It is not necessary to wear laser safety goggles.
