Primary Outcome Measures:
  • Visual Acuity (VA) [ Time Frame: 4 visits over 3 months ]
    Mean high contrast, distance logMAR VA for each eye between the Test and Control lenses. This measure is an average from 4 visits taking place over 3 months.


Secondary Outcome Measures:
  • Slit Lamp > Grade 2 [ Time Frame: 3 months ]
    Proportion of eyes with any slit lamp findings greater than grade 2 at any visit between the Test and Control lenses.


Enrollment: 166
Study Start Date: August 2011
Study Completion Date: January 2012
Primary Completion Date: December 2011 (Final data collection date for primary outcome measure)

Criteria

Inclusion Criteria:

  • Subjects must have clear central corneas and be free of any anterior segment disorders.
  • Subjects must be myopic, and wear contact lenses in each eye.
  • Subjects must be adapted soft contact lens wearers and agree to wear their study lenses on a daily wear basis for approximately 3 months.

Exclusion Criteria:

  • Subjects who are older than age 40 on the date the informed consent (ICF) is signed.
  • 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 any grade 2 or greater finding during the slit lamp examination.
  • 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.
