Primary Outcome Measures:
  • Average Corneal Staining Area [ Time Frame: After 2 hours of wear ] [ Designated as safety issue: No ]
    Percentage corneal staining was assessed by the investigator for each of five regions of the cornea, i.e., four quadrants plus central. The investigator instilled fluorescein dye and examined the cornea with a slit lamp, i.e., biomicroscope and a yellow filter. Percentage corneal staining area was recorded in increments of ten, and the percentages of the five regions were averaged together.

  • Total Corneal Staining Type [ Time Frame: After 2 hours of wear ] [ Designated as safety issue: No ]
    Total corneal staining type was assessed by the investigator for each of 5 regions of the cornea, i.e., four quadrants plus central. The investigator instilled fluorescein dye and examined the cornea with a slit lamp, i.e., biomicroscope and a yellow filter. Corneal staining type was recorded on a 5-point scale for each region: 0-none; 1-micropunctate; 2-macropunctate; 3-coalesced macropunctate; 4-patch (>/= 1mm). The five regions were summed.


Secondary Outcome Measures:
  • Ocular Comfort [ Time Frame: After 2 hours of wear ] [ Designated as safety issue: No ]
    Ocular comfort was recorded by the participant on a questionnaire using a 5-point scale. Participant completed the sentence, "Right now my eyes feel..." with one of the following responses: 1-very comfortable; 2-comfortable; 3-neither comfortable nor uncomfortable; 4-uncomfortable; 5-very uncomfortable.

  • Ocular Redness [ Time Frame: After two hours of wear ] [ Designated as safety issue: No ]
    Ocular redness was recorded by the participant on a questionnaire using a 5-point scale. Participant completed the sentence, "Right now my eyes look..." with one of the following responses: 1-very white; 2-white; 3-neither white nor red; 4-red; 5-very red.
