Purpose: To evaluate safety and effectiveness of the TECNIS toric intraocular lenses (IOLs).
Design: Prospective, multicenter, 2-armed, bilateral, 6-month clinical trial following the American National Standards Institute (ANSI) standard for Toric IOLs.
Participants: Subjects implanted with a TECNIS toric IOL (n = 172) or a TECNIS 1-piece control IOL (ZCB00; n = 93).
According to classical theory, visual acuity (VA) can be modeled using the intersection of the eye's modulation transfer function with a retinal threshold function. To date, there have been limited attempts to validate this methodology by comparing theory with actual measured data. We use the methodology to predict the visual acuity in the presence of defocus of a population of cataract patients implanted with diffractive multifocal intraocular lenses.

Design: One-year, nonrandomized, multicenter, evaluator-masked, bilateral, parallel-group comparative clinical evaluation.
Methods: Subjects underwent bilateral implantation with the TCMF IOL or the CeeOn 911A monofocal (CEMN) IOL (Abbott Medical Optics, Inc) according to subject preference.
