Arms and Interventions

Arm Intervention/Treatment
Experimental: Toric T3 - T9

AcrySof IQ Toric IOL surgically implanted in the capsular bag of the eye following cataract removal. Both eyes were implanted, with the second eye implanted at least 1 week after and within 1 month of the first eye.

Device: Toric T3 - T9
Commercially available, acrylic, multifocal IOL intended to provide visual correction over the lifetime of the cataract patient
Other Names:
  • AcrySof® IQ Toric IOL Models SN6AT3, SN6AT4, SN6AT5, SN6AT6, SN6AT7, SN6AT8, or SN6AT9
  • Active Comparator: IQ SN60WF

    AcrySof IQ IOL surgically implanted in the capsular bag of the eye following cataract removal. Both eyes were implanted, with the second eye implanted at least 1 week after and within 1 month of the first eye.

    Device: IQ SN60WF
    Commercially available, acrylic, monofocal IOL intended to provide visual correction over the lifetime of the cataract patient
    Other Names:
  • AcrySof® IQ IOL Model SN60WF
  • Outcome Measures

    Primary Outcome Measures

    1. Monocular Uncorrected Distance Visual Acuity (Monocular UCDVA) at Month 3 [Month 3]

      Uncorrected visual acuity (i.e., visual acuity measured without spectacles or other visual corrective devices) was assessed using Early Treatment Diabetic Retinopathy Study charts at 100% contrast and measured in logarithm of the minimum angle of resolution (logMAR). Each eye was assessed, and both eyes contributed to the mean. LogMAR 0.00 is equivalent of 20/20 and LogMAR 1.0 is equivalent of 20/200. A more negative logMAR value would indicate a greater improvement in visual acuity.
