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.
