Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
Overall Comfort
Time Frame: 4 weeks
|
Overall comfort was assessed and recorded by the participant on a questionnaire as a single, retrospective evaluation of 4 weeks of wear.
Overall comfort was measured on a 10-point scale, with 1 being poor and 10 being excellent.
|
4 weeks

|
Vision Quality During the Day
Time Frame: 4 weeks
|
Vision quality during the day was assessed and recorded by the participant on a questionnaire as a single, retrospective evaluation of 4 weeks of wear.
Vision quality during the day was measured on a 10-point scale, with 1 being poor and 10 being excellent.

|
Overall Handling
Time Frame: 4 weeks
|
Overall handling was assessed and recorded by the participant on a questionnaire as a single, retrospective evaluation of 4 weeks of wear.
Overall handling was measured on a 10-point scale, with 1 being poor and 10 being excellent.

|
Dryness Throughout the Day
Time Frame: 4 weeks
|
Dryness throughout the day was assessed and recorded by the participant on a questionnaire as a single, retrospective evaluation of 4 weeks of wear.
Dryness throughout the day was measured on a 10-point scale, with 1 being very dry and 10 being not dry.
|
4 weeks
|
|
Average Daily Wear Time
Time Frame: 4 weeks
|
Average daily wear time (hours) was reported by the participant as a single, retrospective evaluation of 4 weeks of wear.

|
Lens Fit
Time Frame: 4 weeks
|
Lens fit was assessed by the investigator for each eye using a biomicroscope, which magnifies the appearance of the contact lens on the participant's eye.
Lens fit was graded on a 5-point scale, with 2=unacceptable loose, 1=acceptable loose, 0=optimal, -1=acceptable tight, and -2=unacceptable tight.
|
4 weeks
|
|
Corrected Visual Acuity
Time Frame: 4 weeks
|
Corrected visual acuity was tested for each eye while the participant read distant charts in normal lighting.
Corrected visual acuity was measured with a Snellen chart, which was converted into logMAR units (logarithm of the minimum angle of resolution).
A 20/20 Snellen acuity equates to a logMAR acuity of 0.0 and is considered normal distance eyesight.
Positive logMAR values indicate poorer vision, and negative values denote better visual acuity.

4 weeks
|
|
Overall Satisfaction
Time Frame: 4 weeks
|
Overall satisfaction was recorded on a 5-point Likert scale as a single, retrospective evaluation of 4 weeks of wear.
The following scale was used: 2=very satisfied, 1=somewhat satisfied, 0=neither, -1=somewhat dissatisfied, and -2=very dissatisfied.
