Presbyopia is treated by implanting within a plurality of elongated pockets formed in the tissue of the sclera of the eye transverse to a meridian of the eye, a prosthesis having an elongated base member having an inward surface adapted to be placed against the inward wall of the pocket and having a ridge on the inward surface of the base extending along at least a major portion of the major dimension of the base. The combined effect of the implanted prostheses is to exert a radially outward traction on the sclera in the region overlying the ciliary body which expands the sclera in the affected region together with the underlying ciliary body. The expansion of the ciliary body restores the effective working distance of the ciliary muscle in the presbyopic eye and thereby increases the amplitude of accommodation. Hyperopia, primary open angle glaucoma and/or ocular hypertension can be treated by increasing the effective working distance of the ciliary muscle according to the invention.

[ I claim:] [1.] An ocular scleral prosthesis adapted for insertion into the sclera of an eye in the region of the ciliary body comprising:a base member having an elongated planform with a major dimension, a minor dimension, an inner major surface and an outer major surface, said outer major surface being generally smooth and adapted to contact ocular tissue within a pocket surgically formed within scleral tissue of the eye, anda ridge member on said base member that applies an outward force to the pocket to thereby elevate the sclera in the region of the ciliary body.
