Study Summary
The purpose of this study is to prospectively evaluate postoperative visual and refractive parameters in a series of subjects bilaterally implanted with the AcrySof® IQ ReSTOR® +3 versus those bilaterally implanted with the Tecnis Multifocal 1-piece.
Primary Outcome
A defocus curve is created by multiple measurements of one's visual acuity at different spherical powers (recorded as Diopters (D)). Visual Acuity (VA) is measured in logMAR. LogMAR is the "logarithm of the minimum angle of resolution".
