Primary Outcome Measures :
  1. Visual Acuity [ Time Frame: over all follow-up visits for 3 month study period ]
    logMAR visual acuity (VA) over all visits.

Secondary Outcome Measures :
  1. Any Slit Lamp Finding > Grade 2 [ Time Frame: over all follow-up visits for the 3 month study period ]
    All dispensed eyes over all follow-up visits. Measured on a scale of 0-4 with 0=no findings and 4=sever findings.

  2. Subjective Response to Comfort, symptoms and complaints [ Time Frame: over all follow-up visits for the 3 month study period ]
    subjective ratings of comfort, symptom and complaints using a scale of 0=severe stinging/Burning to 10=No stinging/Burning for each eye; 0 represented the least favorable rating and a 100 represented the most favorable rating.

  • The presence of clinically significant (grade 3 or 4) anterior segment abnormalities; inflammations such as iritis; or any infection of the eye, lids, or associated structures.
  • A known history of corneal hypoesthesia (reduced corneal sensitivity), corneal ulcer, corneal infiltrates or fungal infections.
  • A history of papillary conjunctivitis that has interfered with contact lens wear.
