Study Summary
The purpose of this study is to evaluate the overall performance of PRECISION1™ contact lenses when compared to INFUSE™ contact lenses.
Primary Outcome
Distance visual acuity (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 inferential testing was pre-specified for this endpoint.
Interventions
- DEVICE Kalifilcon A contact lenses
- DEVICE Verofilcon A contact lenses
