  • Have an Astigmatism of 1.00D or less in both eyes.
  • Require a visual correction in both eyes.
  • Be correctable to a visual acuity of 6/9 (20/30) or better in each eye.
  • Have normal eyes with no evidence of abnormality or disease that would preclude lens wear.
Exclusion Criteria
  • Clinically significant (Grade 3 or 4) corneal edema, corneal vascularization, tarsal abnormalities, bulbar infection, or any other abnormality of the cornea that would contraindicate contact lens wear.

  • Extended wear of contact lenses last 3 months.
  • Polymethyl methacrylate (PMMA) or rigid gas-permeable (RGP) lens wear in the previous 8 weeks.
  • Refractive surgery.
  • Eye injury/surgery within 8 weeks immediately prior to enrollment for this study.
  • Pre-existing ocular irritation that would preclude contact lens fitting.
  • Require concurrent ocular medication
  • Any systemic illness which would contraindicate lens wear or the medical treatment of which would affect vision or successful lens wear.
  • Any infectious disease (e.g., hepatitis, tuberculosis) or any immunosuppressive disease (e.g., HIV).

Primary Outcome Measures
NameTimeMethod
Vision Qualityafter 1 week of lens wear

This outcome is a weighted combined score calculated from individual vision-related questions asked on a 1-5 scale: 1 = most negative response to 5 = most positive response.

Subjective Rating of Handlingafter 1 week of lens wear

This outcome is a weighted combined score calculated from individual lens handling-related questions asked on a 1-5 scale: 1 = most negative response to 5 = most positive response.

Subjective Rating of Quality Perceptionsafter 1 week of lens wear

This outcome is a weighted combined score calculated from individual quality perception-related questions asked on a 1-5 scale: 1 = most negative response to 5 = most positive response.

Corneal Stainingafter 1 week of lens wear

Investigator assessment of the corneal staining. Staining is an indication of dryness on areas on the cornea. Here it is measured over 5 regions of the cornea: central, temporal, nasal, inferior, and superior. The staining is graded using the National Eye Institute (NEI)0-3 scale: grade 0 = normal, grade 1 = mild, grade 2 = moderate, grade 3 = severe.

Limbal Hyperemiaafter 1 week of wear

This outcome is assessed by the investigator during biomicroscopy examination using the following 0-4 scale: 0 = none, 1 = trace, 2 = mild, 3= moderate, 4 = severe.

Subjective Rating of Comfortafter 1 week of lens wear

This outcome is a weighted combined score calculated from individual comfort-related questions asked on a 1-5 scale: 1 = most negative response to 5 = most positive response.
