Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
Proportion of Eyes With Absolute Rotation Less Than or Equal to 10 Degrees
Time Frame: 15-minutes after lens insertion
|
Absolute rotation was assessed for each subject eye using a slit lamp 15-minutes after lens insertion.
Acceptable absolute rotation was dichotomized into a binary response where Y=1 if absolute rotation was less than or equal to 10 degrees and Y=0 otherwise (absolute rotation greater than 10 degrees).
The proportion of eyes with absolute rotation less than or equal to 10 degrees was report for each lens.
|
15-minutes after lens insertion
|
|
Proportion of Eyes With Rotational Stability Less Than or Equal to 5 Degrees
Time Frame: 15-minutes after lens insertion
|
Rotational Stability was assessed for each subject eye using a slit lamp 15-minutes after lens insertion.
Rotational Stability was dichotomized into a binary response where Y=1 if Rotational Stability was less than or equal to 5 degrees and Y=0 otherwise (Rotational Stability greater than 5 degrees).
The proportion of eyes with Rotational Stability less than or equal to 5 degrees was report for each lens.

HLHC Binocular logMAR Visual Acuities
Time Frame: 2-Week Follow-up
|
Binocular visual acuity was measured on a logMAR (Logarithm of Minimal Angle of Resolution) scale under high luminance high contrast condition.
At distance (4 meters), VA is assessed using ETDRS (Early Treatment Diabetic Retinopathy Study) charts; while near (40 cm) and intermediate (64 cm) assessments were made using reduced Guillon-Poling charts.
Letter-by-letter results calculated the visual performance score for each chart read.
LogMAR scores closer to zero, or below zero, indicate a better visual acuity.
A logMAR visual performance score of 0.0 is equivalent to Snellen visual acuity of 20/20.
Data from hyperopes and myopes were combined for this outcome since logMAR scores between the two populations are similar.
|
2-Week Follow-up
|
|
CLUE Vision Scores
Time Frame: 2-Week Follow-up
|
Subjective vision was assessed using the Contact Lens User Experience™ (CLUE) questionnaire.
CLUE is a validated patient-reported outcomes (PRO) questionnaire to assess patient-experience attributes of soft contact lenses (comfort, vision, handling, and packaging) in a contact-lens wearing population in the US, ages 18-65.
Derived CLUE scores using Item Response Theory (IRT) follow a normal distribution with a population average score of 60 (SD 20), where higher scores indicate a more favorable/positive response with a range of 0-120.
The average CLUE vision score for each sphere stratum (Hyperope and Myope) was reported.
|
2-Week Follow-up
|
|
Proportion of Eyes With Grade 3 or Higher Slit Lamp Findings
Time Frame: Up to 2-Week Follow-up
|
Slit Lamp Findings (SLF) were assessed using a biomicroscope and was graded using the FDA grading scale (Grade: 0, 1,2, 3 and 4) with grade 0 represents the absence of findings and 1 to 4 representing successively worse findings (i.e.
Grade 1 = trace, Grade 2 = Mild, Grade 3 = moderate and Grade 4 = severe).
This was performed on each subject eye at every study visit (baseline, unscheduled visits and 1-week follow-up).
The data was then dichotomized into two groups.
Those with grade 3 or higher and those with grade 2 or lower.
The proportion of eyes with SLF with grade 3 or higher was reported.
Data from the hyperope and myopes group were combined for this outcome since the rate of SFLs grade 3+ is similar for these two populations.
|
Up to 2-Week Follow-up
|
|
Proportion of Eyes With Unacceptable Lens Fitting
Time Frame: Up to 2-Week Follow-up
|
Contact lens fitting acceptance was assessed for each subject eye using a biomicroscope post lens insertion at the 1-week follow-up. Lens fit was a binary variable where unacceptable lens fit=1 and acceptable lens fit=0. The proportion of eyes with unacceptable lens fit was reported. Data from the hyperope and myopes group were combined for this outcome since lens fitting characteristics are similar for these two populations. |
Up to 2-Week Follow-up

Proportion of Subject Achieving Optimal Lens Pair in 4 Lenses or Less.
Time Frame: Up to 1-Week Follow-up
|
The number of lenses to achieve the optimal pair for each subject was calculated as the original pair (2) plus all the required modifications to reach the optimal pair.
In this study the minimum number of lenses per subject used was 2 where the maximum possible number of lenses used was 10.
The data was dichotomized as Y=1 if the subject was able to achieve optimal lens pair in 4 lenses or lenses or less and 0 otherwise.
A lens modification was performed if the subject reports unsatisfactory vision or was unable to obtain 20/30 distance visual acuity in both eyes.
If the subject reported satisfactory vision with the lenses a modification was not required.
However, based upon the investigator's findings on the measured visual acuity and/or over- refraction a modification may have been performed.
Data for the hyperope and myope groups were combined for this endpoint since the number of subjects needed to optimize vision is independent of which group a subject belongs to.
