Abstract
The present invention relates to an intraocular lens comprising: a primary lens (1000) having a first focal length, a first surface, and a second surface; a secondary lens (2000) having at least two focal lengths, a first surface (2100), and a second surface (2200), wherein the second surface (2200) of the secondary lens (2000) conforms to the first surface of the primary lens (1000), while the secondary lens (2000) is attached to the primary lens (1000) by peelable adhesive forces over substantially its second surface (2200).
Claims20
An intraocular lens surgically implantable in the capsular bag, sulcus, or in the anterior chamber of the eye, the intraocular lens comprising:
- a primary lens having a first focal length, a first surface, and a second surface, the primary lens having one or more haptic portions for positioning the primary lens in the eye during implantation;
- and
- a secondary lens having a first surface and a second surface, wherein the second surface of the secondary lens conforms to the first surface of the primary lens, while the secondary lens is attached to the primary lens by peelable adhesive forces allowing peeling of the lenses by adhesive rupture on the second surface of the secondary lens, wherein a chemical composition of the primary lens and a chemical composition of the secondary lens are effective to result in a reversible interfacial interaction between the second surface of the secondary lens and the first surface of the primary lens, which includes an optical portion of the primary lens, and allowing removal of the secondary lens while the primary lens remains implanted in the eye without degrading the optical characteristics of the optical portion of the primary lens.
