Brief Summary

The primary objective of thes study is to confirm that the ocular response to the Test lenses are similar to those of the Control lenses when used in a 1 week planned replacement, daily wear modality over a 1-month period.

Detailed Description

The test lens and control lens were randomized in a 2:1 ratio to evaluate the test lens and control contact lens.

Conditions

Ametropia

Eligibility Criteria

Inclusion Criteria

Prior to being considered eligible to participate in this study, each subject MUST:

• Be at least 18 years of age as of the date of evaluation for the study.
• Have read the Informed Consent, been given an explanation of the Informed Consent, indicated understanding of the Informed Consent, signed the Informed Consent document.
• Be willing and able to adhere to the instructions set forth in this protocol and able to keep all specified appointments.
• Be an adapted, current full-time silicone hydrogel or soft contact lens wearer. An adapted full-time wearer is defined as wearing contact lenses in both eyes on a daily basis for at least 8 hours per day for at least one month prior to participation in the study.
• Possess wearable and visually functional eyeglasses.
• Be in good general health, based on his/her knowledge.
• Require spectacle lens powers between -1.00 and -6.00 diopters sphere with no more than 2.00 diopters of refractive astigmatism and be willing to wear contact lenses in both eyes.
• Have: manifest refraction Snellen visual acuities (VA) equal to or better than 20/25 in each eye.
• Upon completing the fitting process with the lenses to be worn in the study, have contact lens Snellen VA equal to or better than 20/30 in each eye.

To be eligible for lens dispensing (either Test or Control), the subject's study lens contact lens visual acuity must be equal to or better than 20/30 in each eye.

Exclusion Criteria

Subjects may not be enrolled in this study if any of the following apply: The subject is/has:

• Wearing lenses in a monovision modality and is unwilling to be fit with distance lenses in both eyes. NOTE: Subjects may not wear lenses in a monovision modality at any time during the study as it will interfere with the visual acuity analysis.
• Poor personal hygiene.
• Any active participation in another clinical trial within 30 days prior to this study.
• Currently pregnant (to the best of the subject's knowledge), is lactating or is planning a pregnancy within the study period.
• A member, relative or household member of the investigator or of the investigational office staff.
• Has a known sensitivity to ingredients used in the care products approved for use in the study.
• Previous refractive surgery; or current or previous orthokeratology treatment.
• Is aphakic or psuedophakic.
• Ocular or systemic disease such as, but not limited to: anterior uveitis or iritis (past or present), glaucoma, Sjögren's syndrome, lupus erythematosus, sclerodermia, keratoconus or type II diabetes.
• The need for topical ocular medications or any medication which might interfere with contact lens wear or which would require the lenses to be removed during the day.
• The presence of clinically significant (grade 3 or 4) anterior segment abnormalities.
• Any; inflammations such as iritis; or any infection or allergic reaction of the eye, lids, or associated structures.
• A known history of corneal hypoesthesia (reduced corneal sensitivity), corneal ulcer, corneal infiltrates or fungal infections.
• A history of papillary conjunctivitis that has interfered with contact lens wear.
• Slit lamp findings that would contraindicate contact lens wear, including but not limited to: Pathological dry eye or associated dry eye symptoms with decreased tear levels and punctuate staining > Grade 2, Pterygium, Corneal scars within the visual axis, Neovascularization or ghost vessels > 1.0 mm in from the limbus, Giant papillary conjunctivitis (GPC) of > Grade 1, Anterior uveitis or iritis, Seborrheic eczema, seborrheic conjunctivitis or blepharitis

• Minimum Eligible Age: 18 Years
