Use of topical ocular over-the-counter or prescribed topical ocular medication, with the exception of rewetting drops, within 7 days prior to screening visit.
Current or history of ocular infection, inflammation, disease, structural abnormality or conditions within the last 6 months that could affect study participation or may preclude safe administration of the investigational lens care solution, in the opinion of the investigator.
Any corneal surgery, cataract surgery, intraocular lens implants or glaucoma filtering surgery within the last 12 months.
Any slit-lamp finding score of 1 (or rated 3 or 4 for limbal and bulbar conjunctival injection) at screening or baseline visits.
Corneal staining area assessment ≥ 20% in any corneal region in either eye at screening or baseline visit.
Corneal staining graded as 2 (macropunctate) or greater in any corneal region in either eye at baseline visit.
Participation in any investigational clinical study within 30 days of baseline visit.
Other protocol-defined exclusion criteria may apply.

Group	Intervention	Description
FID 114675A / RepleniSH	Balafilcon A contact lens (PureVision®)	FID 114675A in Period 1; RepleniSH in Period 2. Each solution was used for 7 days for cleaning, rinsing, conditioning, disinfecting, and storing silicone hydrogel contact lenses, per protocol-specified instructions. A new pair of silicone hydrogel contact lenses was dispensed at the start of each period and worn bilaterally on a daily wear basis.

Primary Outcome Measures

Name	Time	Method
Mean Ex-Vivo Wetting Angle	Day 7, Hour 14	Study lens was removed from the eye according to protocol-specified procedures. The OCA15 (Optical Contact Angle) Instrument was used to observe, record, and calculate contact angle measurements. The wetting angle measurement was recorded in degrees (0-180), and a lower wetting angle measurement indicates a more wettable lens.

Secondary Outcome Measures

Name	Time	Method
Mean Lens Comfort	Day 7, Hour 14	Lens comfort was assessed by the participant on a 5-point Likert scale prior to any examination. The participant was instructed to select a single response to the statement, "My lenses feel comfortable right now," with 1 = strongly disagree, 2 = disagree, 3 = undecided, 4 = agree, and 5 = strongly agree.
Percentage of Participants With Solution-Related Corneal Staining	Day 7, Hour 14	Corneal staining was assessed by the investigator using fluorescein dye, a yellow filter, and a slit lamp. Corneal staining was graded on a continuous scale of 0% (no staining in the region) to 100% (staining covers entire region) in 1% increments for 5 corneal regions (central, nasal, temporal, inferior, and superior). Solution-related corneal staining was defined as ≥20% corneal staining area in at least 3 corneal regions of both eyes and is reported as a percentage of total participants.
