Primary Outcome Measures

Name	Time	Method
Visual Acuity	6 months	Uncorrected 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.

Secondary Outcome Measures

Name	Time	Method
Contrast Sensitivity	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 (log) 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.
Patient Satisfaction	6 Months Postoperative	Average rating of patient satisfaction based on a patient survey. The survey had a 10 point scale (10 being most satisfied and 0 being most unsatisfied).
Spectacle Independence	6 Months	The percentage of patients reporting spectacle independence (no longer needing to wear glasses).
