Which factor is crucial for patient comfort during laser therapy?

Patient comfort during laser therapy is significantly influenced by the amount of energy delivered during the treatment. When the energy level is appropriately calibrated, it helps to ensure that the treatment is effective while also minimizing discomfort for the patient. Excessive energy can lead to heat accumulation and pain, making the experience unpleasant. Conversely, too little energy may not provide the desired therapeutic effects, which can also affect patient comfort and satisfaction.

Factors such as session duration, type of laser, and number of treatments are important for treatment efficacy and planning, but they don't directly address the immediate sensations a patient will experience during a session. The amount of energy delivered is therefore a primary consideration in ensuring that the laser therapy remains tolerable and effective, directly impacting the patient’s overall experience.
