ReSTOR – uses refractive-diffractive lens; aspheric lens (counteracts pos sph aberration) with +2-add power; diffractive/aspheric on front surface;

 

ReZoom – refractive design; distance vision at central and peripheral; near vision mid-periph;

 

Refractive endpoint variable 2nd inability to measure preop capsular bag size (smaller bag = more posterior lens = hyperopia; larger bag = more ant lens = myopia); also, capsular bag contraction can lead to myopic shift;

 

symmetric (very helpful to use 6.5mm ink trephine as rhexis guide);
