Primary outcomePrimary: Mean Ex-Vivo Total Lipid Uptake Per Lens — 7.198; 35.879 micrograms
Summary
The purpose of this study is to evaluate the lipid uptake, wetting characteristics, and visual performance of AIR OPTIX® AQUA and ACUVUE® OASYS® with HYDRACLEAR® contact lenses when used in conjunction with two contact lens care systems.

Eligibility Criteria
Inclusion Criteria
- Read and understand the Participant Information Sheet;
- Read, sign, and date the Informed Consent;
- Be a current silicone hydrogel contact lens wearer using the contact lenses under a frequent replacement (bi-weekly or monthly) daily wear modality;
- Be classified as symptomatic and a depositor at the end of the replacement period according to protocol-specified criteria;
- Agree to wear study contact lenses as directed for the duration of the study and maintain the appointment schedule;
- Best corrected visual acuity of 6/9 or better in each eye;
- Normal eyes with the exception of the need for visual correction;
- Other protocol-defined inclusion criteria may apply.
Exclusion Criteria
- Known sensitivity or intolerance to any of the contact lenses or contact lens care products to be used;
- Monocular vision (only one eye with functional vision or only one eye fitted with contact lenses);
- Use of systemic medication which might interfere with contact lens wear or produce dry eye side effects;
- Systemic disease which might interfere with contact lens wear or produce dry eye side effects;
- Systemic or ocular allergies which might interfere with contact lens wear;
- Ocular disease which might interfere with contact lens wear;
- Active ocular infection;
- Use of any concomitant topical ocular medications during the study period;
- Previous ocular surgery;
- Pregnant, planning to become pregnant, or lactating at the time of enrollment;
- Participation in an investigational drug or device study within 30 days of entering this study;
- Other protocol-defined exclusion criteria may apply.
