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.
