Presbyopia-correcting intraocular lens implant

摘要

A presbyopia correcting intraocular lens implant for implanting in a human eye includes an implant body having a central lens enclosure and at least one stability tab extending therefrom. At least one ciliary body sensor senses movement of the eye's ciliary body. An electronic module is embedded in the implant body and includes a microprocessor communicative with the ciliary body sensor. A dynamic lens assembly is housed in the central lens enclosure and has a dynamic range of continuous accommodation. The lens implant also includes a renewable intraocular power supply.

1. A presbyopia correcting intraocular lens implant for implanting in a human eye, said intraocular lens implant comprising:
an implant body having a central lens enclosure and at least one stability feature extending therefrom; at least one ciliary body sensor for sensing movement of the eye's ciliary body; an electronic module embedded in said implant body, said module including a microprocessor communicative with said at least one ciliary body sensor; a dynamic lens assembly housed in said central lens enclosure and having a dynamic range of continuous accommodation, said dynamic lens assembly further comprising:
an anterior lens defining a visual axis substantially perpendicular thereto;a posterior lens in registration with said anterior lens and translatable with respect thereto along said visual axis;an anterior electromotive ring integrated with said anterior lens and an opposing posterior electromotive ring integrated with said posterior lens for translating said posterior lens with respect to said anterior lens and communicative with said microprocessor; anda dynamic lens assembly coupling system limiting the range of translation of said anterior and posterior lenses with respect to one another; and, a renewable intraocular power supply.
