In this retrospective observational study, the subject used AONDA for at least approximately 1 year in either a daily wear (DW) or continuous wear (CW) modality with monthly replacement. For the CW cohort only, 3-year data will be collected, if available.
The purpose of this study is to assess long term performance and safety of AONDA in a real world setting when worn as daily wear or continuous wear for vision correction. This study will be used to support AONDA's marketability in Europe and other locations.
