Obesity has recognised as one of the main factors responsible for increasing the risk of various potentially deadly diseases. Obesity can be cured, but regardless of treatment, the rapid weight loss often results in certain irregularities in body contours. These imperfections can be corrected by body contouring techniques. Currently, the laser lipolysis technique has become the elective approach for this type of treatment, as it guarantees good results with reduced recovery times and risks. In laser lipolysis, light is delivered using an optical fibre inserted through the cannula under the skin. During the operation, the physician must move the cannula under the skin to properly heat the entire target area.
