Interventions

FID 114675A multi-purpose disinfecting solution (MPDS)DEVICE

Daily regimen, 14 days: Thoroughly wet and rub each side of study contact lens for 10 seconds, rinse each side of the lens for 10 seconds, and soak contact lens for at least 6 hours.

renu fresh Multi-Purpose Solution (MPS)DEVICE

Daily regimen, 14 days: Wet study contact lens with 3 drops and rub each side of the lens for 20 seconds, rinse each side of the lens for 5 seconds, and soak contact lens for at least 4 hours.

Galyfilcon A contact lenses (Acuvue Advance)DEVICE

A fresh pair of contact lenses matching subject's pre-study lenses, including parameters, dispensed at the beginning of each period for daily wear, minimum 8 hours per day, 14 days.

Medical Language ↔ Plain English

Inclusion Criteria: * 18 years of age or older. * History of at least 5 days successful daily wear (minimum 8 hours per day) of spherical, single power Acuvue® Advance® SiH contact lenses prior to Visit 1. * Wear contact lenses a minimum of 8 hours per day prior to Visit 1. * Vision correctable to 20/30 (Snellen) or better in each eye at distance with study lenses at Visit 1. * Other protocol-defined inclusion criteria may apply. Exclusion Criteria: * Need to wear contact lenses on an extended wear basis (i.e., overnight) during the study. * Use of products other than a multi-purpose solution to care for lenses at least 7 days prior to Visit 1. Pre-study use of rewetting drops is acceptable. * History of intolerance or known sensitivity to any component of the treatments. * Use of over-the-counter (OTC) or prescribed topical ocular medications within 7 days prior to Visit 1. * Other protocol-defined exclusion criteria may apply.

Outcomes

Primary Outcomes

Lens Fit

As assessed by the investigator using a composite score based on three lens fit measures: static, push-up, and centration. Static and pushup were assessed on a 5-point scale, where -2=reduced movement unacceptable, -1=reduced movement acceptable, 0=optimal movement, 1=excessive movement acceptable, 2=excessive movement unacceptable. Centration was assessed on a 3-point scale, where 0=optimal lens centration, 1=acceptable decentration, 2=unacceptable decentration. A subject with an assessment of optimal or acceptable for each measure was considered acceptable on all measurements.

Time frame: Day 14 of lens wear

Secondary Outcomes

Mean Change From Baseline for Circumlimbal Conjunctival Staining Sum Score

The bulbar conjunctiva was assessed by the investigator at baseline and Day 14 utilizing a slit-lamp and ophthalmic dye. Staining coverage was scored separately in each of four regions (nasal, temporal, inferior, and superior) using a 5-point photographic reference scale, where 0=0.00% coverage and 4=10% or greater coverage. The scores for the four regions were summed, with a sum score range of 0-16.

Time frame: Day 14 of lens wear
