Intraocular implants
First Claim
Patent Images
1. An intraocular implant, for placement upstream of a retina, comprising:
- a telescope body defining an optical path for light to pass therethrough;
at least one first lens and at least one second lens enclosed in said telescope body;
a variable positioner, enclosed in said telescope body, operative to variably position at least one of said lenses along its optical axis relative to another at least one of said lenses, and to thereby focus objects located at multiple distances onto the retina;
a focus control assembly enclosed in said telescope body and operative to provide control signals to said variable positioner, said focus control assembly comprising electronic circuitry which is arranged to lie in a cylindrical configuration outside said optical path; and
a mounting structure connected to said telescope body for mounting said implant in an eye.

12. A method for adjusting the focal length of a lens arrangement in an intraocular implant upstream of a retina, comprising:
-
providing an intraocular implant comprising; a telescope body defining an optical path for light to pass therethrough; at least one first lens and at least one second lens enclosed in said telescope body; a variable positioner, enclosed in said telescope body, operative to variably position at least one of said lenses along its optical axis relative to another at least one of said lenses, and to thereby focus objects located at multiple distances onto the retina; a focus control assembly enclosed in said telescope body and operative to provide control signals to said variable positioner, said focus control assembly comprising electronic circuitry which is arranged to lie in a cylindrical configuration outside said optical path; and a mounting structure connected to said telescope body for mounting said implant in an eye, implanting said intraocular implant upstream of a retina in an eye; and adjusting the position of said at least one of said lenses relative to said another at least one of said lenses, comprising; providing a control signal from said focus control assembly to said variable positioner; and employing said variable positioner to variably position said at least one of said lenses along its optical axis relative to said another at least one of said lenses, and to thereby focus objects located at multiple distances onto said retina. - View Dependent Claims (13, 14)
