Subject Reported Overall Quality of Lens Vision Using the Contact Lens User Evaluation (CLUE) Questionnaire
Lasso di tempo: After 7 to 9 days of lens wear
|
The overall quality of lens vision was assessed using the CLUE questionnaire after 7-9 days of follow-up.
The CLUE Questionnaire is a validated patient-reported outcomes questionnaire to assess patient-experience attributes of soft, disposable contact lenses in the US, ages 18-65.
Scores follow a normal distribution with a population average score of 60 (SD 20), where higher scores indicate a more favorable/positive response with a range from 0-120.
