Multifocal Lenses
Multifocal Lenses
Description:
EYECRYL ACTV IOLs are diffractive – refractive multifocal IOLs having a series of concentric rings with diffractive steps. The spacing between the steps gets progressively closer from the center of the lens towards the edge. EYECRYL ACTV IOLs use this type of design to provide excellent distance and near vision along with good intermediate vision.
