Abstract
Presbyopia may be treated by implanting a scleral prosthesis within a plurality of elongated pockets formed in the tissue of the sclera of the eye. The implanted prosthesis exerts traction on the sclera in the region overlying the ciliary body which expands the sclera and the underlying ciliary body. This restores the effective working distance of the ciliary muscle and increases the amplitude of accommodation. A prosthesis of the present invention that contacts the sclera of an eyeball comprises a body having a first end and a second end. The body has (i) a planform for expanding the contacted sclera to increase the effective working distance of the ciliary muscle of the eyeball, and (ii) a structure that stabilizes the prosthesis within the surgically formed pocket within the sclera of the eyeball.
