Primary Outcome Measures:
  • Lens Comfort [ Time Frame: Change from baseline to one week ] [ Designated as safety issue: No ]

    Lens comfort was calculated as a weighted combined score from individual comfort-related questions asked on a 1-5 scale. 1 is the most negative and 5 is the most positive. >0 = comfortable, <0 = uncomfortable

    Analysis was performed at the 1 week time point.

Enrollment: 50

Ages Eligible for Study:   21 Years to 39 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Be between 21 and 39 years of age.
  • Signed Written Informed Consent and Investigator to record this on Case Report Form (CRF) in appropriate space.
  • Be existing (i.e. successfully worn for 1-month prior to the study) soft contact lens wearers (no extended wear in the last 3 months, but silicone hydrogels in daily wear are allowed).
  • Require a visual correction in both eyes (monovision allowed but no monofit).
  • Have a contact lens spherical distance requirement between -1.00D and -6.00D in both eyes.
  • Astigmatism of 1.00D or less in both eyes.
  • Be able to wear the lens powers available for this study.
  • Be correctable to a visual acuity of 20/30 or better in each eye.
  • Have normal eyes with no evidence of abnormality or disease. For the purposes of this study a normal eye is defined as one having:

    • No amblyopia.
    • No evidence of lid abnormality or infection.
    • No conjunctival abnormality or infection.
    • No clinically significant slit lamp findings (i.e. edema, staining, scarring, vascularisation, infiltrates or abnormal opacities).
    • No other active ocular disease.

Exclusion Criteria:

  • Requires concurrent ocular medication.
  • Any systemic illness which would contraindicate lens wear or the medical treatment of which would affect vision or successful lens wear.
  • Clinically significant (Grade 3 or 4) corneal edema, corneal vascularisation, corneal staining, tarsal abnormalities, bulbar injection or any other abnormality of the cornea that would contraindicate contact lens wear.
  • Diabetic.
  • Infectious disease (e.g., hepatitis, tuberculosis) or an immunosuppressive disease (e.g., HIV).
  • Extended lens wear in last 3 months.
  • PMMA or RGP lens wear in the previous 8 weeks.
  • Has had refractive surgery. Has had eye injury/surgery within 8 weeks immediately prior to enrollment for this study.
  • Abnormal lacrimal secretions.
  • Pre-existing ocular irritation that would preclude contact lens fitting.
  • Keratoconus or other corneal irregularity.
  • Pregnancy, lactating or planning a pregnancy at the time of enrollment.
  • Participation in any concurrent clinical trial or in last 60 days."
