Outcome Measures
Primary Outcome Measures
- 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).
- 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).
- Residual Refractive Cylinder [6 Month]
Residual Refractive Cylinder at month 6 measured in diopters (D).
Secondary Outcome Measures
- 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. |
