Abstract
A two optic accommodative lens system wherein at least one of the optics is deformable. When compressed by the capsular bag, the two optics press against each other, deforming at least one of the optics. As a result, the interface where the two optics meet changes shape, thereby altering the refractive power of the lens system.
Claims5
An accommodative intraocular lens, comprising:
- a first lens having a first optic having a first interface attached to a first peripheral ring by a first plurality of haptics, wherein the first optic, the first peripheral ring and the first plurality of haptics are formed as a single piece;
- a second lens having a second optic having a second interface attached to a second peripheral ring by a second plurality of haptics, the second peripheral ring sized and shaped to receive the first peripheral ring so that the first interface region is in contact with the second interface region centered on an optical axis of the first optic thereby altering the refractive power of the lens and wherein the second optic, the second peripheral ring and the second plurality of haptics are integrally formed as a single piece;
- wherein the first plurality of haptics bias the first optic against the second optic.
