Patients' satisfaction and subjective happiness after refractive surgery for myopia

The purpose of this study was to assess patients' satisfaction and change in subjective happiness after laser-assisted in situ keratomileusis (LASIK). This was a retrospective cross-sectional study of 307 patients (mean age, 34.3 years; range, 20-63 years) who underwent bilateral LASIK surgery and ocular examinations, including subjective refraction and visual acuity axial length measurements at Minamiaoyama Eye Clinic. Patients also completed questionnaires on their satisfaction with the surgery, and on the subjective happiness scale (SHS) within 1 month before and 1 month after surgery. A multiple regression analysis was performed to determine the independent predictors of the SHS score. In total, 91.2% of the patients were satisfied with surgery (very satisfied: n=155; satisfied: n=125). The SHS score increased postoperatively from 5.2±0.9 to 5.3±0.9 (
