Evaluation of the Effectiveness of Two Marketed Multi-Purpose Solutions for Silicone Hydrogel Contact Lenses - Study 2

In this 2-period crossover study, eligible participants were randomized to either Opti-Free® PureMoist MPDS or RevitaLens MPDS in Period 1 for use with their habitual contact lenses, after which they switched to the alternate solution in Period 2. Each period was 30 days in length. A 2-day washout period during which participants refrained from using a multi-purpose contact lens solution preceded Period 1 and Period 2.
