| 摘要 |
<p>The present invention is generally directed to multi-surface (22) and/or multi-element (10) intraocular lenses (IOLs) in which a plurality of surfaces (24a,24b; 14a,12b) are adapted to provide compensation for a variety of aberrations, and in particular, for off-axis aberrations such as coma or spherical aberration. In one aspect, an intraocular lens is disclosed that includes a posterior optic (14) and an anterior optic (12). One optic provides compensation for a radially symmetric aberration and the other provides compensation for a radially asymmetric aberration.</p> |
