1 Results from a 20-investigator, multi-site cross-over study of PureVision2 For Astigmatism and PureVision Toric lenses. A total of 292 subjects completed the study. After 7 days of wear or each lens, subjects completed an online survey regarding lens performance. Consumers rated performance attributes using a 6-point scale (1 = strongly disagree and 6 = strongly agree) and using a 5-point scale (excellent, very good, good, fair, poor). At the final visit, investigators rated the extent to which they agreed or disagreed with performance attributes also using a 6-point scale.
