Brief summary: The purpose of this study was to evaluate the performance of Opti-Free® PureMoist® Multi-purpose Disinfecting Solution (MPDS) compared to AMO RevitaLens OcuTec® MPDS (US brand name)/COMPLETE RevitaLens (Europe brand name) in silicone hydrogel contact lens wearers.

Detailed description: 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.

Eligibility criteria: Inclusion Criteria:

* Wear single vision sphere silicone hydrogel contact lenses (CooperVision™ Biofinity®, Alcon® Air Optix® Aqua, Bausch+Lomb® PureVision™ or ACUVUE® Oasys™) on a daily wear basis (a minimum of 8 hours per day, 5 days a week) for at least 1 month prior to Visit 1;
* Willing to wear lenses on a daily wear basis (a minimum of 8 hours per day, 5 days a week) for the duration of the study, and wear lenses for 16 hours on 2 days during the study;
* Must have habitually used a biguanide preserved multi-purpose solution (other than RevitaLens) for at least 30 days prior to Visit 1;
* Vision correctable to 20/30 Snellen (feet) or better in each eye at distance with pre-study contact lenses at Visit 1;
* Have access, capability and willingness to review and answer text messages;
* Read, sign, and date IRB/IEC approved informed consent and privacy document before enrollment;
* Willing to follow the study procedures and visit schedule;
* Other protocol-defined inclusion criteria may apply.

Exclusion Criteria:

* Need to wear lenses on an extended wear (i.e overnight) basis during the study;
* Known sensitivity or intolerance to biguanide, polyquaternium-1 (POLYQUAD), or ALDOX preserved lens care products;
* Monocular (only one eye with functional vision) or fit with only one lens;
* Wearing toric or multifocal contact lenses or fit with monovision;
* Use of additional lens care products other than a biguanide preserved multi-purpose solution such as daily or enzyme cleaners within the 1 week prior to Visit 1;
* Use of topical ocular over-the-counter (OTC) or prescribed topical ocular medications, with the exception of rewetting drops, within 7 days prior to Visit 1;
* Abnormal ocular condition observed during the Visit 1 slit-lamp examination;
* Current or history of ocular infections or severe inflammation within 6 months prior to Visit 1;
* Ocular surgery within the 12 months prior to Visit 1;
