Introduction to SubLiminal Laser Therapy

> SubLiminal laser therapy

In contrast to conventional laser photocoagulation, SubLiminal^® laser therapy does not use a continuous-wave laser beam leading to a thermal effect.

SubLiminal^® laser therapy is based on a stimulation concept, using extremely short microsecond laser pulses followed by cooling time periods.

As a result, by using short enough laser pulses (Time on) and long enough cooling times (Time off) the targeted tissue can cool between laser pulses, preventing retinal damages.

How new generation lasers are different from each other
Laser has changed a lot over the years, the newer laser can deliver energy in different ways, by reducing the duration to 10-20 ms, in a train of pulses of 0.1 ms as in the micropulse / subliminal laser, and extremely short duration of 0.0017 ms as in the nanosecond laser. Clinical studies have shown that micropulse laser is efficacious in multiple macular conditions
