The study will evaluate visual acuity and visual function with a 'blended' ReSTOR Toric intraocular lens (IOL) implantation after cataract surgery.
The objective is to provide a normative standard for refractive and visual outcomes in eyes with significant corneal astigmatism undergoing cataract surgery with the Alcon Toric ReSTOR lens. Patients will be bilaterally implanted, with the Toric ReSTOR +2.5D model implanted in the dominant eye and the Toric ReSTOR +3.0D model implanted in the non-dominant eye.

IOL Orientation
Postoperative orientation changes with the Toric ReSTOR IOL up to 3 months after surgery will be measured by determining the angle of orientation of the IOL in degrees (0-180) using a slit lamp.
