a study to evaluate the safety and effectiveness of a contact lens cleaning and disinfecting solution

Conditions: Refractive Ametropia

Summary: approximately 340 participants (680 eyes) will be enrolled in this three-month, two-arm, 1:1 randomized, parallel-group, bilateral, double-masked study at approximately 22 investigative sites in the united states. participants will be required to wear dispensed study lenses on a daily wear basis for three months with scheduled in-office replacement of study lenses at the 1-month and 2-month follow-up visits.
