Abstract
The invention concerns a device for treating presbyopia or other ocular disorders related to any eye accommodation defect. The device (20) includes a piece (22) shaped as a ring portion with an axis of revolution and first (22a) and second (22b) edges offset along radial directions and along the direction of said axis of revolution. The first edge (22a) is disposed to rest, over at least part of its length, on part of the eye internal wall and the second part (22b) is capable of being pressed against a median zone (18c) of zonules of the crystalline lens (18). In this way a displacement of the median zone of said zonules is obtained. This displacement enables them to cause the deformation of the crystalline lens (14) under the effects of stimulation applied to the zonules.
