Evaluation of Three Daily Disposable Contact Lenses

Not Applicable

Completed

Conditions: Visual Acuity

Registration Number: NCT02568254

Lead Sponsor: Johnson & Johnson Vision Care, Inc.

Brief Summary: This is a single-site, 8-visit, double-masked, cross-over study involving three marketed products as study lenses. Participants will be randomly assigned each lens type, which will be worn for approximately two weeks (12 +/- 2 days) each. Participants will undergo a minimum washout period of 3 days before entering the study and undergo a minimum 7 day washout period between dispensing each lens type.

The subject must own a wearable pair of spectacles and wear them the day of the initial visit;
The subject must be an existing wearer of spherical, soft contact lenses in both eyes;
The subject must have normal eyes (i.e., no ocular medications or infections of any type);
The subject must be willing to wear the study lenses for a minimum eight hours per day.

Exclusion Criteria

Any ocular or systemic allergies or diseases that may interfere with contact lens wear (at the investigator's discretion);
Any systemic disease, autoimmune disease, or use of medication, which may interfere with contact lens wear (at the investigator's discretion);
Currently pregnant or lactating (subjects who become pregnant during the study will be discontinued);
Any infectious disease (e.g., hepatitis, tuberculosis) or a contagious immunosuppressive disease;
Any active ocular infection;
Is using any topical medications (excluding artificial tears (ATS)) up to two weeks prior to the screening visit;
Any participants whose habitual contact lenses are used as an extended wear regimen;
Entropion, ectropion, extrusions, chalazia, recurrent styes, glaucoma, history of recurrent corneal erosions, aphakia, or moderate or above corneal distortion by keratometry;
Any previous, or planned, ocular or interocular surgery (e.g., radial keratotomy, photorefractive keratectomy (PRK), laser-assisted in situ keratomileusis (LASIK), etc.);
Clinically significant (grade 3 or 4) corneal edema, corneal vascularization, corneal staining, or any other abnormalities of the cornea which would contraindicate contact lens wear; or clinically significant (grade 3 or 4) tarsal abnormalities or bulbar injection which might interfere with contact lens wear;
Any known hypersensitivity or allergic reaction to the study products;
Participation in any contact lens or lens care product clinical trial within 7 days prior to study enrollment;

Primary Outcome Measures

Name	Time	Method
Overall Comfort	2- Week Follow-up	Clue comfort 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.
