摘要:
An intraocular lens device that includes an intraocular lens optics that provides at least two powers of magnification one being near vision power and the other being distance vision power. The lens optics has surface modulations that are responsible for providing the near vision power. The zone structure provides an add power of over 6 diopters. The add power indicative of an extent that the near vision focusing power is greater than the distance vision focusing power.
