Brief Summary
The purpose of this study is to evaluate the effect that placement and power of the AcrySof Toric has on post-operative visual acuity and spectacle independence for distance vision. This will be determined by comparing manifest refraction pre-operatively and post-operatively and by evaluating the rotational stability of the lens over time.

Outcome Measures
Primary Outcomes (1)
Visual Acuity (VA)
Pre-operative and 1 month, 3 month, and 6 month post-operative visual acuity (VA) measured in logMAR. LogMAR is the "logarithm of the minimum angle of resolution". It is a unit of measure for visual acuity (VA).
Pre-operative, 1 month, 3 month, and 6 month post-operative
Secondary Outcomes (2)
Spectacle Independence
6 months post-operative
IOL Rotation
6 months post-operative
Study Arms (1)
AcrySof Toric IOL
EXPERIMENTALAcrySof Toric Intraocular Lens (IOL)
Interventions
Implantation with the AcrySof Toric IOL for cataract replacement and multiple follow-up assessments
