Primary Outcome Measures :
  1. Slit Lamp Findings [ Time Frame: 6 months ]
    Each subjects' eye was examined using a bio-microscope. Slit lamp findings were graded using a 5- point scale. (Grade 0, 1, 2, 3 and 4). The data was dichotomized by creating 2 groups. Eyes with Grade 3 or Grade 4; eyes with Grade 2 or lower. The number of eyes with Grade 3 or Grade 4 was reported.

  2. Subject Reported Symptoms [ Time Frame: 6 months ]
    Subjects were asked "Have you experienced any symptoms or problems since your last visit?" at each visit and responded 'yes' or 'no' for each eye; at each visit(baseline, 2-, 4-, 12- and 26- week follow-up evaluations). If a subject responded 'yes' then the symptoms was classified into one of the four categories, "Dryness", "Other", "Cloudy/ Blurry / Hazy", "Irritation / Discomfort". The percentage of each response across all visits was reported.

  3. Visual Acuity [ Time Frame: 6 months ]
    Binocular LogMAR Visual Acuity was taken under low luminance and high contrast conditions using ETDRS acuity charts.

  4. Average Contact Lens Wear Time [ Time Frame: 6 Months ]
    The Contact lens wear time for the study contact lenses was collected for each subject. The average wear time for each contact lens was reported.
