| 摘要 |
An intraocular lens is disclosed which includes a central portion having a first refractive power region and a peripheral portion having a second refractive power region. The second refractive power region is substantially concentrated only in one predetermined location; or is asymmetrically disposed on the inferior nasal quadrant of the intraocular lens. In a preferred configuration, the second refractive power region has more refractive power than the first refractive power region. Preferred configurations may additionally or alternatively include a toric surface and/or a prism. |
