Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The objective of this study is to evaluate the safety and effectiveness of the Bausch + Lomb samfilcon A soft (hydrophilic) contact lens, a new silicone hydrogel contact lens, compared to the Bausch + Lomb PureVision® soft contact lens when worn for 7-day extended wear by adapted soft contact lens wearers.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Approximately 816 participants (1,632 eyes) will be enrolled in this 12-month randomized, parallel, Investigator/Sponsor masked study at approximately 35 investigative sites in the US.

At the Screening/Dispensing Visit, approximately one-half of the participants will be randomized to receive Bausch + Lomb investigational samfilcon A soft contact lenses (Test) and approximately one-half of the subjects will be randomized to receive Bausch + Lomb PureVision soft contact lenses (Control). Both groups will wear the assigned lenses bilaterally on a 7-day extended wear basis throughout the 12 month study. The lenses are to be worn overnight for up to six consecutive nights per week. The lenses are to be removed, cleaned and disinfected on the seventh night and re-inserted the following morning. The lenses will be replaced with new lenses at the beginning of each month. Lenses will be provided at the Screening/Dispensing, 3-Month, 6-Month and 9-Month Follow-Up visits to maintain a monthly replacement schedule. Participants will also be required to complete a paper diary.

Bausch + Lomb Samfilcon A Soft Contact Lens

Participants will wear Bausch + Lomb samfilcon A soft contact lens in each eye on a 7-day extended daily wear basis for a period of 12 months. The lenses will be worn overnight for up to 6 consecutive nights per week. The lenses will be removed, cleaned, and disinfected with Biotrue multi-purpose solution on the seventh night and re-inserted the following morning. The lenses will be replaced with new lenses on the first monday of each month.

Bausch + Lomb Pure Vision Soft Contact Lens

Participants will wear Bausch + Lomb pure vision soft contact lens in each eye on a 7-day extended daily wear basis for a period of 12 months. The lenses will be worn overnight for up to 6 consecutive nights per week. The lenses will be removed, cleaned, and disinfected with Biotrue multi-purpose solution on the seventh night and re-inserted the following morning. The lenses will be replaced with new lenses on the first monday of each month.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Participants must be correctable through spherocylindrical refraction to 42 letters (0.1 logMAR) or better (distance, high contrast) in each eye.
* Participants must be adapted lens wearers and wear a lens in each eye; each lens must be of the same manufacturer and brand.
* Participants must be myopic and require lens correction from -0.50 diopters (D) to 6.00 D in each eye.
* Participants must have clear central corneas and be free of any anterior segment disorders.
* Participants must agree to wear their lenses on an extended wear basis (6 nights/7 days) for the duration of the study.

Exclusion Criteria

* Participants who have worn gas permeable (GP) contact lenses within the last 30 days or who have worn polymethylmethacrylate (PMMA) lenses within the last three months.
* Participants with an active ocular disease or who are using any ocular medication.
* Participants with any systemic disease currently affecting ocular health or which in the Investigator's opinion may have an effect on ocular health during the course of the study.
* Participants using any systemic medications that will, in the Investigator's opinion, affect ocular physiology or lens performance.
* Participants who are not correctable to 42 letters (0.1 logMAR) in each eye with soft spherical contact lenses.
* Participants who currently wear monovision, multifocal, or toric contact lenses.
