About this trial
This is an interventional treatment trial for Dry Eye Syndrome focused on measuring contact lens, dry eye syndrome, symptomatic, daily disposable, myopia
Eligibility Criteria
Inclusion Criteria:
- Currently wearing weekly/monthly, silicone hydrogel or traditional hydrogel soft contact lenses at least 8 hours per day and 5 days a week during the past 6 months.
- Identified as symptomatic using a baseline screening questionnaire.
- Requires vision correction in both eyes with a contact lens prescription as follows: sphere powers between -0.50 and -10.00 diopter (D) and cylinder powers </= 0.75D and no ADD correction.
- Able to achieve visual acuity (VA) of at least 6/7.5 in each eye with study lenses in the available parameters.
- Willing to wear study lenses for at least 8 hours/day and at least 5 days/week and discard the lenses at the end of the day and replace lenses every day with a new fresh pair.
- Willing and able to follow instructions and maintain the appointment schedule.
- Other protocol-defined inclusion criteria may apply.
Exclusion Criteria:
- Neophytes and current wearers of daily disposable contact lenses.
- Requires monovision correction.
- Any systemic or ocular disease or disorder (refractive disorder allowed) complicating factors or structural abnormality that would negatively affect the conduct or outcome of the study.
- A history of ocular surgery/trauma within the last 6 months.
- Unwilling to discontinue mechanical eyelid therapy or eyelid scrubs within 14 days of enrollment and continuing during the study.
- Participation in any other ophthalmic drug or device clinical trial within 30 days of enrollment.
- Other protocol-defined exclusion criteria may apply.

Arms of the Study
Arm 1
Arm Type
Experimental
Arm Label
DAILIES® AquaComfort Plus®
Arm Description
Nelfilcon A contact lenses worn bilaterally on a daily wear, daily disposable basis for 2 weeks
Outcomes
Primary Outcome Measures
Mean Change From Baseline in Contact Lens-Related Dryness Symptoms at Week 1 and Week 2
Contact lens symptoms were evaluated using the Contact Lens Dry Eye Questionnaire (CLDEQ). Subjects rated 8 common contact lens-related ocular surface dryness symptoms at Baseline, Week 1, and Week 2 using a 5-point scale (1=never or not at all intense, 5=constantly or very intense). A scoring algorithm was used to calculate a composite score for each visit for all symptoms (-6.5 to 10). A higher composite score would indicate more contact lens related dry eye and a lower score, less contact lens related dry eye.
