Beskrivelse
Inclusion Criteria:
- Have physiologically normal anterior segments not exhibiting clinically significant biomicroscopy findings.
- Be adapted wearers of soft contact lenses, wear a lens in each eye, and each lens must be of the same manufacture and brand.
- Be correctable through spherocylindrical refraction to 32 letters (0.3 logMAR) or better (distance, high contrast) in each eye.
- Be myopic and require lens correction from -0.50 diopters (D) to -6.00 D in each eye.
- Must agree to wear the study lenses on a daily wear basis for the duration of the study.
- Must be willing to use a lens care system on a regular basis.
- If the subject requires a Washout Period, the subject must be willing to discontinue contact lens wear and be willing to wear either spectacles or no lenses during this Washout Period.
Exclusion Criteria:
- Not correctable to 32 letters (0.3 logMAR) in each eye with soft spherical contact lenses.
- Have an active ocular disease, any corneal infiltrative response or are using any ocular medications.
- Have worn gas permeable (GP) contact lenses within last 30 days or PMMA lenses within last 3 months.
- Any scar or neovascularization within the central 4mm of the cornea.
- Any Grade 2 or greater finding during the slit lamp examination, Subjects with corneal infiltrates, of ANY GRADE, are not eligible.
- Any "Present" finding during the slit lamp examination that, in the Investigator's judgment, interferes with contact lens wear.
- Anisometropia (spherical equivalent) of greater than 2.00 D.
- Any systemic disease affecting ocular health.
- Using any systemic or topical medications that will affect ocular physiology or lens performance.
- Aphakic.
- Amblyopic.
- Allergic to any component in the study products.
- Have had any corneal surgery (ie, refractive surgery).
- Currently wear monovision correction, multifocal, or toric contact lenses.
- Ocular astigmatism greater than 1.00 D in either eye.

Symptoms and Complaints
Tidsramme: At 1 Week follow up
|
Symptoms/complaints were assessed on a scale from 0 to 100, with 0 denoting unfavorable symptoms/complaints.
Symptoms/complaints were recorded for each eye based on the participant's experience with their study lenses worn for that respective treatment period.
Symptoms/complaints parameters included the following: Burning/stinging upon insertion, Comfort upon insertion, Overall comfort, Comfort at end of day, Ease of handling/insertion, Ease of handling/removal, Dryness, Itchiness, Redness, Vision upon insertion, Vision, Vision in low light, Lens cleanness upon insertion, Lens cleanness upon removal, Lens cleanness, Dryness at end of day, and Overall impression.
