Potential subjects must satisfy all of the following criteria to be enrolled in the study:
- The subject must read, understand, and sign the STATEMENT OF INFORMED CONSENT and receive a fully executed copy of the form.
- Appear able and willing to adhere to the instructions set forth in this clinical protocol.
- Between 18 and 49 (inclusive) years of age at the time of informed consent.
- Eligible presbyopes will be those that wear full distance contact lenses in both eyes, then wear reading glasses over them when needed for near vision.
- The subject is a current spherical soft contact lens wearer in both eyes with a minimum of 6 hours/day and 5 days/week wear time over the last 30 days by self-report.
- Subjects must be able and willing to wear the study lenses at least 6 hours a day, a minimum of 5 days per week.
- Subjects must own a wearable pair of distance spectacles.
- The subject's vertex-corrected spherical equivalent distance refraction must be in the range of -1.00 to -6.00 D (inclusive) in each eye.
- The subject's refractive cylinder must be 0.00 to -1.00 D (inclusive) in each eye.
The subject must have a spherocylindrical best corrected distance Snellen visual acuity of 20/25+3 or better in each eye.
Exclusion Criteria:
Potential subjects who meet any of the following criteria will be excluded from participating in the study:
- Currently pregnant or lactating (subjects who become pregnant during the study will be discontinued).
- Any active or ongoing systemic disease (e.g., Sjögren's Syndrome), infectious disease (e.g., hepatitis, tuberculosis), contagious immunosuppressive diseases (e.g., HIV), autoimmune disease (e.g. rheumatoid arthritis).
- Subjects taking suspect oral medications for less than one year.
- Any prescribed or over the counter (OTC) ocular medication.
- Any known hypersensitivity or allergic reaction to Optifree® PureMoist® multi-purpose care solution or Eye-Cept® rewetting drop solution.
- Toric, extended wear, monovision or multi-focal contact lens correction.
- Any previous or planned (during the course of the study) ocular surgery (e.g., PRK, LASIK, etc.).
- Participation in any contact lens or lens care product clinical trial within 30 days prior to study enrollment.
- Participation in clinical trials involving the Test lens within 3 months prior to study enrollment.
- Employee or immediate family member of an employee of clinical site (e.g., Investigator, Coordinator, Technician).
- Binocular vision abnormality or strabismus by self-report or prior medical history.
- History of recurrent corneal erosions, herpetic keratitis, or pathological dry eye.
- Any active ocular allergies, infections or other ocular abnormalities (entropion, ectropion, extrusions, chalazia, recurrent styes, glaucoma) that the investigator determines may interfere with the outcomes of this study or otherwise contraindicate participation in the study.
- Any Grade 2 or greater slit lamp findings (e.g., edema, corneal neovascularization, corneal staining, tarsal abnormalities, conjunctival injection) on the FDA Slit Lamp Classification Scale.
- Any previous history or signs of a contact lens-related corneal inflammatory event (e.g., past peripheral ulcer or round peripheral scar) within the past 3 years of otherwise successful contact lens wear.

---|---|---|
Overall Comfort Score
Aikaikkuna: 2-Week Follow-up Evlauation
|
Overall comfort was assessed using the Contact Lens User Experience™ (CLUE) questionnaire.
CLUE is a validated patient-reported outcomes (PRO) questionnaire to assess patientexperience 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.

2-Week Follow-up Evlauation
|
Vision Satisfaction in Bright Lighting
Aikaikkuna: 2-Week Follow-up Evaluation
|
Vision satisfaction in bright light was assessed using the individual item" I was satisfied with the quality of my vision in bright lighting" from the CLUE™ questionnaire.
This item used the response scale, 1: Strongly Disagree, 2: Disagree, 3: Neither Agree nor Disagree, 4: Agree and 5: Strongly Agree.
CLUE is the Contact Lens User Experience™ 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 Proportion of responses in each category were reported for each lens type.
|
2-Week Follow-up Evaluation
|
Distance Visual Acuity
Aikaikkuna: 2-Week Follow-up Evlauation
|
Distance visual acuity was assessed by eye using LogMAR visual acuity at 4 meters using an ETDRS chart under high illumination high contrast conditions (room illumination > 400 lux and chart luminance 120-200 cd/m2) at the 2-week follow-up for each subject eye.
Lower values of logMAR indicate better vision, where a score of 0.0 equates to 20/20 snellen vision.
The average visual acuity for each lens was reported.
|
2-Week Follow-up Evlauation
|
Contact Lens Fitting Acceptance Rate
Aikaikkuna: Up to 2-Week Follow-up
|
Acceptable lens fit will be assessed at all study visits (scheduled and unscheduled) for each subject eye. Fit acceptance rate will be based on the lens fit acceptance of eyes wearing the Test lens only. Fit acceptance is a binary response where Y=1 if lens fit is acceptable and Y=0 otherwise. Unacceptable is defined as unacceptable if any one of the following criteria:
Eyes with multiple unacceptable fitting events will be counted only once. Fit rates of the Control lens will also be collected but are not a primary endpoint. |
Up to 2-Week Follow-up
|
Number of Grade 3 or Higher Slit Lamp Findings
Aikaikkuna: Up to 2-Week Follow-up Evlauation
|
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).
Slit Lamp Findings will be assessed for each subject eye at all study visits (schedule and unscheduled).
SLF is a binary response where Y=1 for at least one Grade 3 or 4 slit lamp finding.
The percentage of eyes with Grade 3 or higher slit lamp findings will be analyzed and will include corneal infiltrates.
Eyes with multiple events will be counted only once.
The number of eyes with SLF with grade 3 or higher by lens was reported.
