Abstract
Intraocular lens combinations are provided which include a first optic having a negative optical power and being adapted to be placed in a substantially fixed position in a mammalian eye. A second optic having a higher optical power than the first optic is provided. In addition, a movement assembly is provided which is coupled to the second optic and is adapted to cooperate with the eye to effect accommodating movement of the second optic in the eye. Very effective accommodation is provided with the present intraocular lens combination. The present combinations can be effectively positioned to effectively inhibit or reduce the risk of posterior capsular opacification (PCO).
Claims24
A system of intraocular lens combinations for a plurality of patients each requiring different vision corrections, comprising:
- one of a plurality of the same high plus power optics configured to cooperate with the eye and provide accommodation;
- and
- one of a plurality of optics each having a different negative power than the others and being configured to maintain a substantially fixed axial position after implantation in a patient's eye;
- wherein the optical powers of the high plus power and negative power optic in any one combination provide a net plus power to the combination, and wherein a magnitude of the negative power optic of any one combination is selected based on the required vision correction for a particular patient.
An intraocular lens combination, comprising:
- a negative power optic configured to maintain a substantially fixed axial position after implantation in the capsular bag of a patient's eye;
- and
- a plus power optic formed and implanted separately from the negative power optic and configured to be implanted in the capsular bag of the eye in an anterior position relative to the negative power optic, the plus power optic configured to provide accommodation.
