Pseudo-accommodative IOL having multiple diffractive patterns

A multifocal ophthalmic lens, comprising

• an optic having a surface comprising at least one bifocal diffractive pattern and one trifocal diffractive pattern, said bifocal pattern being adapted to provide near and far vision and said trifocal pattern being adapted to provide near, far and intermediate vision.

A trifocal ophthalmic lens, comprising

• an optic having at least one surface characterized by a base curve,
• at least two annular diffractive patterns disposed on said optic, one of said patterns providing primarily three foci and the other providing primarily two foci such that a combination of energy distribution associated with the foci of one pattern with that of the other pattern results in providing near, intermediate and far vision.

A multifocal ophthalmic lens, comprising an optic having a surface comprising two separate bifocal patterns, said patterns exhibiting different add powers so as to cooperatively provide near, intermediate and far vision.
