The STORZTM TRUE VISTATM bifocal intraocular lens was evaluated in a laboratory setting and during clinical trials. The modulation transfer function and through focus response were measured in a simulated eye chamber for selection of optimal add zone size, location, power, and pupil dependency. Results indicate the optimal design to be an annular add power of +4 D having a 1.5 millimeter inner diameter and a 2.6 millimeter outer diameter. Optical performance was predicted using computer ray trace and Fourier analysis. Laboratory testing confirmed design performance achieved through the manufacturing process. Clinical results correlate well with through focus response but less well with modulation transfer function.
