Visual Acuity
Number of eyes with Distance Visual Acuity 20/20 or better
Time frame: 15-20 minutes
Patient Reported Vision
A weighted combined score calculated from individual confort-vision related questions asked on a 1-5 scale, 1=most negative resonse to 5=most positive response, was used to derive vision scores. The analysis shows the difference in outcome between test and control. \>0=greater vision, \<0=lesser vision.
Time frame: 15-20 minutes
Lens Orientation Within 5 Degrees
Meaures in what position does the lens sit on the eye at insertion and is measured in degrees of rotation.
Time frame: 1 minute
Lens Stability Within 5 Degrees
Measures if the lens changes position on the eye as it is worn and is measured in degrees of rotation.
Time frame: 1 minute
Patient Reported Comfort.
A weighted combined score calculated from individual comfort-related questions asked on a 1-5 scale, 1=most negative response to 5=most positive response, was used to derive comfort outcomes. The analysis shows the difference in outcome between the test and control. \>0=comfortable, \<0=uncomfortable
Time frame: 15-20 minutes
Patient Preference
This outcome measures which lens the subjects preferred to wear.
