  1. *One participant’s data was removed in this category only as it appeared to have an error
  2. aTwo participants data missing. ^Multiple answers possible. ~ This question was not collected on the demographic form in Germany so this information has been generated from what the patient reported during the interview. In addition, one patient reported myopia in the demographic form but reported that they did not have myopia during the interview. The clinician also reported that this patient did not have myopia, so this patient has not been counted as a myopic patient in the analyses of findings. †Clinicians were not asked to confirm diagnosis of myopia for the round 1 interviews
