An apparatus, system and method for constricting a cornea of a human eye are disclosed. A control device external to the subject eye, such as an induction generator, may be configured to create a stimulus, such as a magnetic field, for an implanted ring that, when stimulated, may change the curvature, and thus the dioptric power, of the eye, thereby approximating natural accommodation.

1. A method for actively constricting a cornea of a human eye, the method comprising: receiving a stimulus from external to the human eye; and inducing a constriction in a ring implanted on or in the cornea, wherein the constriction alters the shape of the cornea in accordance with the received stim
1. A method for actively constricting a cornea of a human eye, the method comprising: receiving a stimulus from external to the human eye; and inducing a constriction in a ring implanted on or in the cornea, wherein the constriction alters the shape of the cornea in accordance with the received stimulus, the ring able to contract or relax in a controlled way in order to affect curvature of the cornea, the stimulus comprises a magnetic field generated by an induction generator, and the inducing comprises a magnetic coupling to the magnetic field; whereby changing curvature of the cornea, the ring changes dioptric power of the cornea and dioptric power of the eye. 2. The method of claim 1, further comprising increasing the dioptric power in accordance with the induced constriction. 3. The method of claim 1, wherein the received stimulus comprises a predefined voltage. 4. The method of claim 1, wherein the ring comprises an ionic polymeric material. 5. The method of claim 1, wherein the stimulus is remote from the ring. 6. The method of claim 1, wherein the ring comprises a silicon shell. 7. The method of claim 1, wherein the ring is coated with a collagen film.
