The objective of this study is to determine to what extent the use of a software application prior to refractive surgery involving multisensory immersion (visual and auditory) in a hypnotic and relaxing sound and visual environment can reduce anxiety levels.
The assessment of preoperative anxiety levels will be based on the administration of a psychometric scale (APAIS scale) and the measurement of salivary cortisol, which is a sensitive marker of the patient's stress level.
