The invention comprises a device for treating presbyopia. A stretch segment is provided for intraocular implantation into the annular sulcus region defined by the intersection of the iris and ciliary body. The stretch segment engages and exerts an outward radial tension against the ciliary body. The segment is designed to take up slack in the equatorial zonules in the presbyopic eye, such that their effective working distance is enhanced. This aids in the accommodation process which affects the curvature of the lens for near viewing. The segment may a closed ring, or may be open ended.
