Primary Outcome Measures :
  1. Uncorrected Visual Acuity (UCVA) at Distance, Near and Intermediate [ Time Frame: 6 months ]
    Uncorrected Visual Acuity (UCVA) at distance, near and intermediate, measured in logMAR. LogMAR is the "logarithm of the minimum angle of resolution". It is a unit of measure for visual acuity (VA). A lower logMAR value indicates better visual acuity.


Secondary Outcome Measures :
  1. Contrast Sensitivity [ Time Frame: 6 months ]
    Contrast sensitivity is the measurement of one's ability to detect slight changes in luminance before it becomes indistinguishable. It is measured in logarithmic units by means of an illuminated box, the CSV 1000 by Vector Vision. A higher value for the logarithmic units translates to better contrast sensitivity.

  2. Defocus Curve [ Time Frame: 6 months post-operative ]
    Defocus cureve. A defocus curve is created by multiple measurements of one's visual acuity at different spherical powers. Visual Acuity (VA) is measured in logMAR. LogMAR is the "logarithm of the minimum angle of resolution". A lower logMAR value indicates better visual acuity.
