Primary Outcome Measures

Name	Time	Method
Percentage of Eyes With Visibly Clean Lenses at Each Visit	Day 7, Day 30, Day 60, Day 90, Day 135, Day 180	Worn study lenses were removed and evaluated for deposits. Deposits found on the lenses were defined using a 3-part classification system consisting of general visibility, the specific appearance and area covered. A lens was considered visibly clean if it had nondetectable films or deposits. Both eyes contributed to the analysis.
Number of Eyes With Film Deposits on Lens by Type at Each Visit	Day 7, Day 30, Day 60, Day 90, Day 135, Day 180	Worn study lenses were removed and evaluated for deposits. Deposits found on the lenses were defined using a 3-part classification system consisting of general visibility, the specific appearance and area covered. Both eyes contributed to the analysis.
Number of Eyes With Crystalline Deposits on Lens by Type at Each Visit	Day 7, Day 30, Day 60, Day 90, Day 135, Day 180	Worn study lenses were removed and evaluated for deposits. Deposits found on the lenses were defined using a 3-part classification system consisting of general visibility, the specific appearance and area covered. Both eyes contributed to the analysis.
Percentage of Lens Area Covered by Film Deposits at Each Visit	Day 7, Day 30, Day 60, Day 90, Day 135, Day 180	Worn study lenses were removed and evaluated for deposits. Deposits found on the lenses were defined using a 3-part classification system consisting of general visibility, the specific appearance and area covered. For each visit, the number analyzed represents the number of eyes with film deposits on lens, respectively.
Percentage of Lens Area Covered by Crystalline Deposits at Each Visit	Day 7, Day 30, Day 60, Day 90, Day 135, Day 180	Worn study lenses were removed and evaluated for deposits. Deposits found on the lenses were defined using a 3-part classification system consisting of general visibility, the specific appearance and area covered. For each visit, the number analyzed represents the number of eyes with film deposits on lens, respectively.
Percentage of Eyes With Change From Baseline in Contact Lens-Corrected Distance Visual Acuity (CLCDVA) by Line Change at Each Visit	Day 7, Day 30, Day 60, Day 90, Day 135, Day 180	Distance VA was assessed for each eye individually while reading a chart distant to the participant in dimmed room illumination. VA was measured using Decimal acuity, where 1.0 (equivalent to 20/20) is considered normal distance-eyesight. A line increase indicates an improvement in VA. Both eyes contributed to the analysis
Average Rewetting Drop Frequency at Each Visit	Day 0, Day 7, Day 30, Day 60, Day 90, Day 135, Day 180	Subject recorded a response to the question, "Averaging over the last 3 days, how many times per day did you use rewetting drops?" Habitual lenses were used at the Day 0 time point.
Average Lens Wear Time (Averaged Over the Last 3 Days) at Each Visit	Day 0, Day 7, Day 30, Day 60, Day 90, Day 135, Day 180	Subject recorded a response to the question, "Averaging over the last 3 days, how many hours per day did you wear your contact lenses?" Lens wear time was summarized as an estimate of the subject's daily wear, averaged over the course of 3 days prior to each scheduled visit, and measured in hours. Habitual lenses were used at the Day 0 time point.
Lens Wear Time at Each Visit Day	Day 0, Day 7, Day 30, Day 60, Day 90, Day 135, Day 180	Subject recorded a response to the question, "How many hours have you worn your contact lenses today?" Lens wear was measured in hours. Habitual lenses were used at the Day 0 time point.
Likert Item - "When I Use This Solution, my Lenses Are Comfortable All Day."	Day 0, Day 7, Day 30, Day 60, Day 90, Day 135, Day 180	Lens comfort was assessed by the subject as a single response on a 5-point Likert scale (Strongly Agree, Agree, Undecided, Disagree, Strongly Disagree) to best describe their lens wearing experience over the last 3 days. Responses were summarized by agreement category and presented as percentage of subjects. Habitual lenses and habitual lens care solution were used at the Day 0 time point.
Likert Item - "When I Use This Solution, I Like the Way This Product Feels During Handling."	Day 0, Day 7, Day 30, Day 60, Day 90, Day 135, Day 180	Product handling was assessed by the subject as a single response on a 5-point Likert scale (Strongly Agree, Agree, Undecided, Disagree, Strongly Disagree) to best describe their lens wearing experience over the last 3 days. Responses were summarized by agreement category and presented as percentage of subjects. Habitual lenses and habitual lens care solution were used at the Day 0 time point.
Number of Unscheduled Lens Replacements by Reason	Up to Day 180	Subjects were dispensed enough contact lenses to follow a 2-week replacement schedule during the study. Lenses replaced at other times were considered unscheduled. The counts in the table represent the total number of unscheduled lenses replaced by reason for any eye, any subject. All lenses which were replaced are counted. Habitual lenses were used at the Day 0 time point.
Likert Item - "When I Use This Solution, at the End of the Lens Wearing Day my Vision is Clear."	Day 0, Day 7, Day 30, Day 60, Day 90, Day 135, Day 180	Clear vision was assessed by the subject as a single response on a 5-point Likert scale (Strongly Agree, Agree, Undecided, Disagree, Strongly Disagree) to best describe their lens wearing experience over the last 3 days. Responses were summarized by agreement category and presented as percentage of subjects. Habitual lenses and habitual lens care solution were used at the Day 0 time point.
