Summary

This study is a randomized, 4-visit, subject-masked, 2x3 bilateral crossover, dispensing trial. Each study lens will be worn bilaterally in a daily wear (DW) modality for at least 6 hours per day and 5 days per week for approximately two weeks each. The subject will wear either the Test or Control lens twice and the other study lens once.

Eligibility Criteria

Inclusion Criteria

  • The subject must read and sign the Informed Consent form.
  • The subject must appear able and willing to adhere to the instructions set forth in this clinical protocol.
  • Healthy adult males or females age ≥18 and ≤49 years of age with signed informed consent. Eligible presbyopes will be those that wear full distance contact lenses in both eyes, then wear reading glasses over them.
  • The subject's optimal vertexed spherical equivalent distance correction must be between -1.00 and -6.00 D.
  • The subject's refractive cylinder must be ≤ 1.00 D in each eye.
  • The subject must have visual acuity best correctable to 20/25+3 or better for each eye.
  • Subjects must own a wearable pair of spectacles.
  • The subject is a current spherical soft contact lens wearer (defined as a minimum of 6 hours of DW per day, at least 5 days per week, for a minimum of 1 month prior to the study) and willing to wear the study lenses on a similar basis.
  • Subjects must be able and willing to wear the study lenses at least 6 hours a day, a minimum of 5 days per week.
  • The subject must have normal eyes (i.e., no ocular medications or infections of any type).

Exclusion Criteria

  • Currently pregnant or lactating (subjects who become pregnant during the study will be discontinued).
  • Any 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, recurrent herpes simplex/zoster, Sjögren's syndrome, xerophthalmia, acne rosacea, Stevens-Johnson syndrome, and immunosuppressive diseases or any infectious diseases (e.g. hepatitis, tuberculosis).
  • Use of any of the following medications within 1 week prior to enrollment: oral retinoid isotretinoin (e.g. Accutane), oral tetracyclines, topical scopolamine, oral (e.g., Chlor-Trimeton, and Benadryl) and ophthalmic antihistamines, oral phenothiazines (e.g., Haldol, Mellaril, Thorazine, Elavil, Pamelor, Compazine), oral and ophthalmic Beta-adrenergic blockers (e.g., Propranolol, Timolol, and Practolol), systemic steroids, and any prescribed or over the counter (OTC) ocular medication.
  • Entropion, ectropion, extrusions, chalazia, recurrent styes, glaucoma, history of recurrent corneal erosions, aphakia, or moderate or above corneal distortion.
  • Any previous, or planned, ocular or intraocular surgery (e.g., radial keratotomy, photorefractive keratectomy (PRK), LASIK, etc.).
  • Any Grade 3 or greater slit lamp findings (e.g.., edema, corneal neovascularization, corneal staining, tarsal abnormalities, conjunctival injection) on the FDA classification scale, 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.
  • Any known hypersensitivity or allergic reaction to Optifree® PureMoist® multi-purpose care solution or Eye-Cept® rewetting drop solution.
  • Any ocular infection, allergy or clinically significant ocular disease (e.g. corneal edema, uveitis, severe keratoconjunctivitis sicca, ocular hypertension), or ocular conditions (e.g. strabismus), which might interfere with the study.
  • Any corneal distortion resulting from previous hard or rigid gas permeable contact lens wear.
  • Toric, extended wear, monovision or multi-focal contact lens correction.
  • 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.
  • History of binocular vision abnormality or strabismus.
  • Employee, relative or friends of employees of any ophthalmic company, or investigational clinic (e.g., Investigator, Coordinator, Technician).
