Beskrivelse
Inclusion Criteria:
- Subjects must be correctable through spherocylindrical refraction to 32 letters (0.3 logMAR) or better (distance, high contrast) in each eye.
- Subjects must be free of any anterior segment disorders.
- Subjects must be adapted soft contact lens wearers and wear a lens in each eye and each lens must be of the same manufacture and brand.
- Subjects must be myopic and require contact lens correction from -0.50 D to -6.00 D in each eye.
- Subjects must be willing and able to wear the study lenses for at least 8 hours (12 hours or more is recommended) each day throughout the duration of the study.
- Subjects must use a technologic device for an average of 4 hours per day over a week's time and at a minimum of 4 days per week.
Exclusion Criteria:
- Subjects who have worn gas permeable (GP) contact lenses within the last 30 days or who have worn polymethylmethacrylate (PMMA) lenses within the last three months.
- Subjects with any systemic disease currently affecting ocular health or which in the Investigator's opinion may have an effect on ocular health during the course of the study.
- Subjects using any systemic or topical medications that will, in the Investigator's opinion, affect ocular physiology or lens performance.
- Subjects with an active ocular disease or who are using any ocular medication.
- Subjects with corneal infiltrates, of ANY GRADE, are not eligible.
- Subjects with any "Present" finding during the slit lamp examination that, in the Investigator's judgment, interferes with contact lens wear.
- Subjects with any scar or neovascularization within the central 4 mm of the cornea.
- Subjects who have had any corneal surgery (eg, refractive surgery).
- Subjects who are allergic to any component in the study care products.
- Subjects may not use their habitual rewetting drops while participating in this study.

Percentage of Eyes With > Grade 2 Slit Lamp Findings
Tidsramme: 2 weeks
|
Graded slit lamp findings for each eye, including epithelial edema, epithelial microcysts, corneal staining, limbal and bulbar injections, upper lid tarsal conjunctival abnormalities, corneal neovascularization, and corneal infiltrates were graded for severity on a scale from 0 (No Finding) to 4 (Severe Finding).
The outcome measure is any finding > grade 2, across abnormalities.

Initial Lens Performance Survey
Tidsramme: At dispensing
|
A lens performance survey was given to each participant at the Screening/Dispensing Visit, three minutes following insertion of the study lenses.
Lens performance was assessed by eye for the following parameters: burning/stinging upon insertion, comfort upon insertion, ease of handling/insertion, vision upon insertion, and lens cleanness upon insertion.
As with symptoms/complaints, responses were on a scale from 0 to 100, with 0 being the most unfavorable score.
