Effective laser therapy administration is a direct function of power and time as it relates to the dose delivered. Administering the optimal treatment dose to patients produces consistent positive outcomes. Class IV therapy lasers provide more energy to deep structures in less time. This ultimately assists in providing an energy dose that results in positive, reproducible outcomes. Higher wattage also results in faster treatment times and provides changes in pain complaints that are unachievable with low power lasers. LightForce lasers provide a level of versatility unrivaled by other Class I, II, and IIIb lasers due to their ability to treat both superficial and deep tissue conditions.
