Clinical Trial Summary

This study is a randomized, single-masked, crossover clinical trial. There are two study lenses. Each lens will be dispensed for 3 ± 1 days and then an optimization visit will occur. The final lens pair will be dispensed for 12 ± 2 days and the follow-up on the final lens pair will occur. The second study lenses will then be fit and the above sequence repeated.

Exclusion Criteria:

• Potential subjects who meet any of the following criteria will be excluded from participating in the study:

1. Currently pregnant or lactating.

2. Any active or ongoing ocular or systemic allergies that may interfere with contact lens wear.

3. Any active or ongoing systemic disease, autoimmune disease, or use of medication, which may interfere with contact lens wear. This may include, but not be limited to, diabetes, hyperthyroidism, Sjögren's syndrome, xerophthalmia, acne rosacea, Stevens- Johnson syndrome, and immunosuppressive diseases or any infectious diseases (e.g. hepatitis, tuberculosis).

4. Any previous, or planned, ocular or intraocular surgery (e.g. radial keratotomy, PRK, LASIK, lid procedures, cataract surgery, retinal surgery, etc.).

5. A history of amblyopia, strabismus or binocular vision abnormality.

6. Use of any of the following medications within 1 week prior to enrollment: oral retinoid isotretinoin (e.g. Accutane), oral tetracyclines, oral phenothiazines, oral/topical/inhaled anticholinergics, systemic/topical corticosteroids.

7. Use of any ocular medication, with the exception of rewetting drops.

8. History of herpetic keratitis.

9. History of irregular cornea.

10. History of pathological dry eye.

11. Participation in any contact lens or lens care product clinical trial within 30 days prior to study enrollment.

12. Employee or immediate family member of an employee of clinical site (e.g., Investigator, Coordinator, Technician).

13. Any known hypersensitivity or allergic reaction to Optifree®Replenish® multipurpose care solution, sodium fluorescein or non-preserved rewetting drop solutions.

14. Clinically significant (Grade 2 or greater) corneal edema, corneal vascularization, corneal staining, tarsal abnormalities or bulbar injection, or any other corneal or ocular abnormalities which would contraindicate contact lens wear.

15. Entropion, ectropion, extrusions, chalazia, recurrent styes, glaucoma, history of recurrent corneal erosions.

16. Any current ocular infection or inflammation.

17. Any current ocular abnormality that may interfere with contact lens wear.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Binocular Contact Lens-Corrected Visual Performance Under Standard High Contrast Bright	The contact lens-corrected visual performance on logMAR scale was evaluated binocularly under high luminance high contrast, dim luminance high contrast and high luminance low contrast conditions at 4 meters (distance), 64 cm (intermediate) and 40 cm (near) using ETDRS/reduced Guillon-Poling charts. A value of 0.0 logMAR equates to 20/20 vision on a Snellen Scale. Lower values indicate better visual performance. The average visual performance was reported for each lens type and distance.	2-Week Follow-up
Primary	Binocular Contact Lens-Corrected Visual Performance Under Standard High Contrast Dim With Goggles	The contact lens-corrected visual performance on logMAR scale was evaluated binocularly under high luminance high contrast, dim luminance high contrast and high luminance low contrast conditions at 4 meters (distance), 64 cm (intermediate) and 40 cm (near) using ETDRS/reduced Guillon-Poling charts. A value of 0.0 logMAR equates to 20/20 vision on a Snellen Scale. Lower values indicate better visual performance. The average visual performance was reported for each lens type and distance.	2-Week Follow-up

The average visual performance was reported for each lens type and distance.	2-Week Follow-up
Secondary	Overall Vision Scores	Overall vision scores were 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, aged 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
Secondary	Overall Comfort Scores	Overall comfort scores were 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, aged 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
Secondary	Number of Grade 3 or Higher Slit Lamp Findings	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 were assessed at the 2-Week Follow-up. SLF is a binary response where Y=1 for at least one Grade 3 or 4 slit lamp finding. The number of eyes with SLF with grade 3 or higher by lens was reported.	2-Week Follow-up
Secondary	Proportion of Subjects That Reported Ocular Symptoms	Subject reported ocular symptoms were assessed using a questionnaire at the 2-week follow-up. Subjects were asked if they experienced any of the following symptoms: Burning/Stinging, Itchiness/Scratchiness, Dryness, Lens Awareness, Grittiness/Foreign Body Sensation, Redness, Irritation/Discomfort, Cloudy/Blurry/Hazy, Variable Vision and Other; using the scale of: None, Mild, Moderate and Severe. The proportion of subjects that reported symptoms (Mild, Moderate and Severe) was reported for each lens type.	2-Week Follow-up
