Primary Outcome Measures:
  • Pre-Lens Non-Invasive Tear Break-Up Time (PL-NITBUT) [ Time Frame: Day 7 ] [ Designated as safety issue: No ]
    Pre-Lens Non-Invasive Tear Break-Up Time will be assessed using a modified CA-1000 topographer. PL-NITBUT will be recorded at the first sign of mire distortion. An average of three measurements will be taken.
