Lens conversion system for teledioptic or difractive configurations

An intraocular lens, adaptable for implantation in an eye, for modifying the lens system of the eye comprising the cornea of the eye and a natural or artificial lens in the eye, the intraocular lens comprising:

• a lens portion which has substantially no refractive power and diffracts light passing therethrough, and is adapted for implantation in the eye at a location relative to the locations of the cornea and the natural or artificial lens in the eye to modify the lens system of the eye such that the modified lens system directs light rays passing therethrough onto an area on the retina of the eye other than an area onto which the light rays are directed by the lens system absent the intraocular lens.

A method for modifying a lens system of the eye comprising the cornea of the eye and a natural or artificial lens in the eye, the method comprising the steps of:

• providing an intraocular lens comprising a first portion which is substantially non-refractive and a second portion;
• and
• implanting the intraocular lens into the eye at a location relative to the locations of the cornea and the natural or artificial lens in the eye to modify the lens system of the eye such that the second portion is positioned to alter a path of light rays passing therethrough to provide the eye with magnified vision when the light rays pass through a lens external of the eye before passing through the second portion.

An intraocular lens, adaptable for implantation in an eye, for modifying a lens system of the eye comprising the cornea of the eye and a natural or artificial lens in the eye, the intraocular lens comprising:

• a substantially non-refractive portion which permits passage of light rays therethrough without altering a path of propagation of the light rays, the substantially non-refractive portion including a portion, adapted to alter a path of propagation of the light rays passing therethrough to alter the lens system of the eye to direct light rays passing therethrough onto an area on the retina of the eye other than an area onto which the light rays are directed by the lens system absent the intraocular lens.
