- Lead Sponsor
- Alcon Research
- Brief Summary
The primary objective of this study is to evaluate the overall performance of PRECISION1 contact lenses when compared to Clariti 1-Day contact lenses.
- Detailed Description
Subjects are expected to attend 3 study visits and wear the PRECISION1 and Clariti 1-Day study lenses in a crossover design for approximately 8 days of exposure to each study lens type. The expected duration of subject participation is up to 22 days.

Group Intervention Description PRECISION1, then Clariti 1-Day Verofilcon A contact lenses Verofilcon A contact lenses worn first, with somofilcon A contact lenses worn second, as randomized. Each study lens type will be worn bilaterally (in both eyes) for 8 -0/+3 days in a daily disposable modality. Clariti 1-Day, then PRECISION1 Verofilcon A contact lenses Somofilcon A contact lenses worn first, with verofilcon A contact lenses worn second, as randomized. Each study lens type will be worn bilaterally (in both eyes) for 8 -0/+3 days in a daily disposable modality. Clariti 1-Day, then PRECISION1 Somofilcon A contact lenses Somofilcon A contact lenses worn first, with verofilcon A contact lenses worn second, as randomized. Each study lens type will be worn bilaterally (in both eyes) for 8 -0/+3 days in a daily disposable modality. PRECISION1, then Clariti 1-Day Somofilcon A contact lenses Verofilcon A contact lenses worn first, with somofilcon A contact lenses worn second, as randomized. Each study lens type will be worn bilaterally (in both eyes) for 8 -0/+3 days in a daily disposable modality.
- Primary Outcome Measures
Name Time Method Distance Visual Acuity (VA) With Study Lenses Day 8 (-0/+3 days) after 10 (-2/+6) hours of wear, each study lens type Distance VA was assessed with study lenses in place. VA was collected for each eye separately using logarithmic of the Minimum Angle of Resolution (logMAR) charts. A logMAR acuity of 0.0 corresponds to 20/20 Snellen acuity (normal visual acuity), with a negative value denoting better than 20/20 visual acuity. No formal hypothesis was predefined for the primary endpoint. No inferential testing was performed.
