Ex-vivo Adhesion of Bacteria to Different Contact Lens Materials

WithdrawnNA

Sponsor: Johnson & Johnson Vision Care, Inc.

Conditions: Visual Acuity

Interventions: 1-DAY ACUVUE MOIST, DAILIES AQUA COMFORT PLUS

This is a single-site, 4-visit, contralateral, dispensing, open-label, randomized study. Each eligible subject will be randomized into one of two sequence groups to wear two lens types contralaterally (Test on the right eye and Control on left eye or vice versa).

Eligibility overview

Sex: ALL

Age: 18 Years to 45 Years

Healthy volunteers: Yes

Study type: INTERVENTIONAL

Eligibility criteria

Inclusion Criteria:

* Potential subjects must satisfy all of the following criteria to be enrolled in the study.

1. The subject must read, understand, and sign the STATEMENT OF INFORMED CONSENT and receive a fully executed copy of the form.
2. Appear able and willing to adhere to the instructions set forth in this clinical protocol.
3. Between 18 and 45 (inclusive) years of age at the time of screening.
4. Be 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.
5. Have a pair of spectacles with corrected vision of 20/40 or better in each eye or uncorrected vision is 20/40 or better in each eye
6. The subject's vertex-corrected spherical equivalent distance refraction must be in the range of -1.00 through -6.00 D in each eye.
7. The subject has a best-corrected visual acuity of 20/25 or better in each eye.

Exclusion Criteria:
* Potential subjects who meet any of the following criteria will be excluded from participating in the study.

1. Currently pregnant or breastfeeding.
2. Any ocular or systemic allergies or diseases that may interfere with contact lens wear.
3. Any autoimmune disease or use of medication, which may interfere with contact lens wear. Habitual medications used by successful soft contact lens wearers are considered acceptable.
4. Any ocular abnormalities such as entropion, ectropion, extrusions, chalazia, recurrent styes, history of recurrent corneal erosions.
5. Any previous, or planned, ocular or interocular surgery (e.g., radial keratotomy, PRK, LASIK, etc.).
6. Multifocal, toric or extended wear contact lens correction.
7. Participation in any contact lens or lens care product clinical trial within 14 days prior to study enrollment.
8. History of binocular vision abnormality or strabismus.
9. Any infectious disease (e.g., hepatitis, tuberculosis) or contagious immunosuppressive diseases (e.g., HIV) by self-report.
10. Employee or immediate family member of an employee of clinical site (e.g., Investigator, Coordinator, Technician).
11. Any ocular infection.
12. Any Grade 3 or greater slit lamp findings (e.g., edema, corneal neovascularization, corneal staining, tarsal abnormalities, conjunctival injection) on the EFRON scale (Appendix G), any previous history or signs of a contact lens-related corneal inflammatory event (e.g., past peripheral ulcer or round peripheral scar), or any other ocular abnormality that may contraindicate contact lens wear.
13. Any corneal distortion resulting from previous hard or rigid gas permeable contact lens wear.
