PureVision2 For Astigmatism contact lenses : Additional information


*PureVision2 for Astigmatism contact lenses are indicated for daily wear or extended wear of up to thirty days. As with any contact lens, problems can result in serious injury to the eye, including loss of vision, and clinical studies have shown that the risk of serious adverse reactions is increased when lenses are worn overnight. It is essential that patients follow the eye care practitioner’s direction and all labeling instructions for proper use of lenses and lens care products. Consult the package insert for complete information.

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.
