Vision correction with laser refractive index changes

A method for providing an intraocular telescope lens system in an eye, comprising:

• providing a negative power lens element in the eye by (i) inserting an intraocular lens comprising a negative power lens element in the eye, or (ii) modifying the refractive index of crystalline lens tissue of the eye by irradiating select regions of the crystalline lens tissue with a focused, visible or near-IR laser below the optical breakdown threshold of the crystalline lens tissue to form a negative power lens element in the crystalline lens that exhibits a change in refractive index relative to non-irradiated crystalline lens tissue, and exhibits little or no scattering loss, and scanning over the select regions with the laser such that ablation or removal of the tissue is not observed in the irradiated region, and
• modifying the refractive index of cornea tissue of the eye by irradiating select regions of the cornea tissue with a focused, visible or near-IR laser below the optical breakdown threshold of the cornea tissue to provide a positive power lens element in the cornea that exhibits a change in refractive index relative to non-irradiated cornea tissue, and exhibits little or no scattering loss, and scanning over the select regions with the laser such that ablation or removal of the tissue is not observed in the irradiated region, and
• wherein the negative and positive power lens elements are aligned along an optical axis in the eye.
