Refitting Acuvue Oaysis Contact Lens Wearers into P7 Contact Lenses

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to evaluate the success of refitting satisfied wearers of Acuvue Oaysis contact lenses into Precision 7 contact lenses, which are designed for astigmatism and incorporate a unique moisturizing system. Participants will be adults aged 18 to 40 who have been wearing Acuvue Oaysis lenses for at least three months and have a specific range of astigmatism. The study will assess how well these individuals adapt to the new lenses over a one-week period, focusing on comfort and visual acuity. The findings will provide insights for practitioners on the feasibility of transitioning patients to this newer lens technology.
