The present invention relates to an intraocular secondary lens (L) for insertion into the eye other than the lens that is implanted in the eye during cataract surgery so as to change the refractive power and/or to change the direction and shape of the image rays entering the eye in the patient who have undergone cataract surgery and to whom intraocular lenses are inserted. The secondary lens (L) is in a form that can be easily adhered on the primary lens (M) or the capsule (4) in which the primary lens is located and be easily removed from thereto, it has a foldable feature and contains adhesive nanostructures (6) thereon. It can be easily applied to the eye without need for structures such as hole, notch, foot etc. on the primary lens (M) with the invention by means of the nano structures (6) on the secondary lens. Said secondary lens (L) may be in the form of normal refractive, diffractive, accommodative, and toric, trifocal, multifocal, or combinations thereof, or optionally may carry devices with different optical properties.

An accommodating (re-focusable) lens system a body of which includes, upon being assembled, first and second individual lenslets having first and second optical portions sequentially disposed along an optical axis. Change in optical-power accommodation of the system is achieved by changing an applanated area of contact between the lenslets in response to force applied to the lenslets and transformed into an axial force. In specific case, the first and second lenslets form an intraocular lens (IOL) and have respective haptic portions, interlocked as a result of rotating of one lenslet with respect to another such as to bring first and second lenslets in contact at an axial point. The applanated area of contact is changed, then, in response to a radially-directed force caused by a change of distance between the interlocked ends of the haptics and transferred to the optical portions through the interlocked haptics. When installed in a natural lens capsule after the cataract extraction, the optical power of such IOL is gradually modifiable due to a change of curvature of the capsule caused by operation of a ciliary muscle.

An intraocular lens system comprising at least one intraocular lens having an anterior surface and a posterior surface, wherein at least one surface of the lens is aspherical to provide for a continuum of retinal images to be focused at the retina in an area between two retinal eccentricities. The system may include an anterior light-converging intraocular lens 16 for positioning within the eye, the anterior lens having an anterior surface and a posterior surface; and a posterior light-diverging intraocular lens 17 for positioning within the eye posterior to the anterior lens, the posterior lens having an anterior surface and a posterior surface; wherein one or both surfaces of the anterior lens and/or one or both surfaces of the posterior lens are aspherical.

Devices and methods for replacing a human lens after cataract surgery. The device is an insert for the eye capsule and is formed of two or more rings that are connected to one another. A primary lens is affixed to the insert. A secondary add-in lens can be added to the insert in a subsequent surgery to correct, or further optimize, the optical results obtained with the initial surgery.

The present disclosure provides intraocular artificial lenses having a variable optical strength and methods of treating an eye disorder, such as presbyopia, using same. In some embodiments, the intraocular artificial lens comprises two optical elements that are moveable along the optical axis in relation to each other, for example in response to the accommodative process of the eye.

An intraocular lens is provided. The intraocular lens includes an optical part and an adjoining haptic part. The optical part includes an optically imaging element and a telescope, the entire telescope being integrally formed and being integrated in the optical imaging element. The optically imaging element has a convexly-curved front side and a concavely-curved rear side. Further, the optically imaging element is arranged as a single lens system.

A system includes an intraocular pseudophakic contact lens configured to be implanted in an eye and mounted on or attached to an artificial intraocular lens in the eye. The system also includes an external lens configured to be positioned in front of the eye. The intraocular pseudophakic contact lens and the external lens form a telescopic Galilean vision system. The external lens may include a spectacle lens or a contact lens. The intraocular pseudophakic contact lens may include an optical lens configured to provide a minus power optical magnification, and the external lens may be configured to provide a plus power optical magnification. The optical lens of the intraocular pseudophakic contact lens may include a central portion configured to provide a minus power optical magnification and an annular portion surrounding the central portion and configured to provide a different power optical magnification or no optical magnification.
