Arm Intervention/treatment
Active Comparator: Monofocal
Patients unilaterally implanted with ReSTOR lens in one eye and previously implanted with monofocal Intraocular lens (IOL) (unspecified) in other eye
Device: ReSTOR
AcrySof ReSTOR +4 Intraocular Lens (IOL) unilaterally implanted
Active Comparator: Phakic
Patients unilaterally implanted with ReSTOR lens in one eye and phakic in the other eye with no necessary cataract removal impending
Device: ReSTOR
AcrySof ReSTOR +4 Intraocular Lens (IOL) unilaterally implanted

Primary Outcome Measures :
  1. Visual Acuity [ Time Frame: 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 :
  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 (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.

  2. Patient Satisfaction [ Time Frame: 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).

  3. Spectacle Independence [ Time Frame: 6 Months ]
    The percentage of patients reporting spectacle independence (no longer needing to wear glasses).
