Calculating fluence in laser treatment specifically refers to determining the energy delivered per unit area, usually measured in joules per square centimeter (J/cm²). Fluence is a crucial factor in laser therapy because it influences the effectiveness of the treatment and ensures that the energy used is appropriate for the condition being treated.

In laser procedures, the energy emitted by the laser is concentrated over an area, and understanding fluence helps practitioners adjust the laser settings to achieve the desired therapeutic effect. For example, different tissues may require varying fluence levels to stimulate healing or achieve desired results while minimizing damage to surrounding areas. Thus, calculating fluence allows practitioners to tailor treatments to individual needs and ensures safety and efficacy.
