Arms and Interventions

Arm Intervention/Treatment
Experimental: AcrySof Toric T3

Each enrolled eye receives AcrySof Toric Model SN60T3 Intraocular Lens (IOL)

Each enrolled eye implanted with the AcrySof Toric Model SN60T3 intraocular lens (IOL) for the treatment of cataract.

Outcome Measures

Primary Outcome Measures

  1. Uncorrected Distance Visual Acuity [6 months]

    Uncorrected Distance Visual Acuity at month 6 measured in logMAR. LogMAR is the "logarithm of the minimum angle of resolution". It is a unit of measure for visual acuity (VA).

  2. Best Corrected Distance Visual Acuity [6 Months]

    Best Corrected Distance Visual Acuity at month 6 measured in LogMAR. LogMAR is the "logarithm of the minimum angle of resolution". It is a unit of measure for visual acuity (VA).

  3. Residual Refractive Cylinder [6 Month]

    Residual Refractive Cylinder at month 6 measured in diopters (D).

Secondary Outcome Measures

  1. Patient Satisfaction Survey [6 months]

    Satisfaction for daytime distance vision, nighttime distance vision, and indoors distance vision on a scale of 1 to 5, with 1 being very dissatisfied and 5 being very satisfied.

Study Results

Participant Flow

Recruitment Details Patients were >21 years of age, of any race and either gender. Patients had operable cataracts in at least 1 eye and were able to provide informed consent. Patients were free of systemic diseases affecting ocular health and had a predicted residual corneal astigmatism between 0.75 and 1.03 Diopters (D) by the AcrySof Toric calculator.
Pre-assignment Detail During the preoperative exam, subjects were examined to ensure they met the inclusion/exclusion criteria. Only subjects who signed an informed consent and qualified to be in the study by meeting all inclusion/exclusion criteria were enrolled.
