What determines the safety and efficacy of laser therapy?

The safety and efficacy of laser therapy are significantly influenced by the specific laser wavelength used. Each wavelength penetrates tissues differently and has varied effects on biological tissues, making it crucial for achieving desired therapeutic outcomes. For instance, certain wavelengths are better suited for targeting particular types of tissue—whether they are superficial or deeper.

Using the appropriate wavelength ensures that the energy from the laser interacts effectively with the tissues to promote healing, reduce inflammation, or alleviate pain, depending on the intended purpose of the therapy. Additionally, the wavelength impacts the absorption characteristics of different tissues, meaning that an inappropriate choice can lead to ineffective treatment or potential harm. Therefore, selecting the correct laser wavelength is fundamental to ensuring that laser therapy is both safe and effective for the specific conditions being treated.

Ensuring the highest level of safety and efficacy requires a deep understanding of the interaction between laser wavelengths and tissue types, making it a critical factor in any laser therapy protocol.
