Abstract
Presbyopia and hyperopia are treated by a method which increases the amplitude of accommodation by increasing the effective working distance of the ciliary muscle in the presbyopic eye. The effective working distance of the ciliary muscle can be increased by expanding the sclera in the region of the ciliary body. This expansion may be accomplished by suturing to the sclera in the region of the ciliary body a relatively rigid band having a diameter slightly greater than that of the sclera in that region. The scleral expansion band comprises anterior and posterior rims and a web extending between the rims, the anterior rim having a smaller diameter than the posterior rim.
Claims63
A scleral expansion band adapted for fastening to the sclera of a human eyeball in the region of the ciliary body, said band comprising an anterior rim and a posterior rim, said anterior rim being sized to lie adjacent the anterior portion of a segment of the sclera of the human eyeball overlying the ciliary body of said eyeball and said posterior rim being sized to lie adjacent the posterior portion of said scleral segment, and rigid structural means extending between said rims and spacing said rims apart so that said anterior rim will lie outside said anterior portion of said scleral segment when said posterior rim lies outside said posterior portion of said scleral segment, at least one of said anterior rim, said posterior rim and said rigid structural means having a diameter greater than the exterior diameter of said scleral segment adjacent thereto.
A scleral expansion band adapted for suturing to the sclera of a human eyeball in the region of the ciliary body, said band comprising a thin frustoconical band having an anterior rim and a posterior rim, said anterior rim having a generally circular shape, said anterior rim being sized to lie adjacent the anterior portion of a segment of the sclera of the human eyeball overlying the ciliary body of said eyeball and having a first diameter, said posterior rim having a generally circular shape, said posterior rim being sized to lie adjacent the posterior portion of said scleral segment and having a second diameter, said first diameter being less than said second diameter, and a rigid web extending between said anterior rim and said posterior rim.
