title: Patient satisfaction and clinical outcomes after overnight orthokeratology.
abstract: OBJECTIVE
  To assess patient satisfaction following overnight orthokeratology using a visual analogue scale and to find clinical factors that influence patient satisfaction.
  
  
  METHODS
  In this prospective study, subjective patient satisfaction with visual outcomes was measured using a visual analogue scale, ranging from 0 (very dissatisfied) to 10 (very satisfied) in 17 patients who completed 1-year follow-up examinations after commencement of orthokeratology. Spherical equivalent refraction at baseline was 2.17 +/- 0.84 diopter (mean +/- SD). Various clinical parameters including refraction, visual acuity, ocular higher-order aberrations, and photopic and mesopic contrast sensitivity function were examined before and after the procedure. The influence of these parameters on patient satisfaction was evaluated using Spearman rank correlation test.
  
  
  RESULTS
  The overall satisfaction with visual outcomes was scored 7.8 +/- 1.8 (range, 3.5 to 10). The level of satisfaction showed significant correlation (Spearman rank correlation coefficient; r = -0.599, p = 0.017) with posttreatment uncorrected visual acuity and pretreatment myopic error (r = 0.500, p = 0.045).
  
  
  CONCLUSIONS
  This study demonstrated a relatively high level of patient satisfaction following overnight orthokeratology. Posttreatment uncorrected visual acuity is associated with patient satisfaction, and patients with higher myopia are predisposed to lower levels of subjective satisfaction.
