Detailed Description
This study was conducted as a series of ten smaller studies in three countries using commercially available contact lens solutions per each country, ie, United Kingdom, France, and the Philippines. In each study, participants were assessed after use of up to 5 products (with one always being a control saline/blister pack solution) in randomized order in conjunction with one of the silicone hydrogel contact lenses. A total of 278 participants were enrolled in the 10 studies.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Contact lens solution #1
|
Device: Contact lens multi-purpose solution
Lens care solutions CE-marked for intended use. A fresh pair of contact lenses was soaked overnight in the test contact lens solution and a pre-cycled lens case prior to study visit, then worn for two hours on the day of the study visit. Up to four solutions were evaluated in randomized order with the same brand of contact lenses, and a minimum of 12 hours of no lens wear separated each wear period.
Other Names:
Device: Contact lenses
CE-marked silicone hydrogel contact lenses soaked overnight for at least 10 hours prior to the study visit, then worn for two hours on the day of the study visit. A fresh pair of the same brand of contact lenses was used for each overnight soak (ie, 4 solutions plus saline/blister pack solution), and a minimum of 12 hours separated each wear period.

| Experimental: Contact lens solution #2

A fresh pair of contact lenses was soaked overnight in the test contact lens solution and a pre-cycled lens case prior to study visit, then worn for two hours on the day of the study visit. Up to four solutions were evaluated in randomized order with the same brand of contact lenses, and a minimum of 12 hours of no lens wear separated each wear period.

Other: Saline/blister pack solution
A fresh pair of contact lenses was soaked overnight in saline prior to study visit or was inserted directly from the blister pack, then worn for two hours on the day of the study visit.
