Abstract
An intraocular lens for correcting of refraction, includes at least one optical lens with an optical axis; and haptics, connected to the optical lens, for positioning the lens in front of the capsular bag of an eye, for example arranged to be placed in the sulcus of the eye; wherein haptics include at least one ring shaped flexible arm, preferably at least a pair of ring shaped flexible arms arranged on opposite sides of the optical lens, preferably as seen perpendicular to the optical axis. The optical lens includes an optical power element for correcting the refractive power of an eye. The optical lens further includes a multifocal optical surface for extending the depth of field of an eye.
