Laser procedure for treatment of presbyopia and other eye disorders
A segmented scleral expansion band adapted for implantation within or fastening to a segment of the sclera of an eye lying outside of and adjacent to the ciliary body of the eye, is formed from a number of arcuate segments, curved to match the curvature of the globe of the eye, and joined together at each end to form a complete scleral expansion band. The band is implanted in the sclera of the eye by forming circumferential tunnels, inserting the band segments through the tunnels, and joining the ends of the segments to form a complete scleral expansion band. The scleral expansion band is useful in treating presbyopia and other ocular disorders.
1. A method, comprising:
increasing a diameter of a sclera overlying a ciliary body of an eye as a function of irradiating at least a portion of the sclera;
wherein increasing the diameter of the sclera comprises reducing a thickness of the sclera in a region of the ciliary body without forming an opening completely through the sclera;
wherein increasing the diameter of the sclera increases a working distance of a ciliary muscle of the eye.
2. A method, comprising:
weakening a sclera of an eye using laser irradiation to increase a diameter of the sclera overlying a ciliary body of the eye;
wherein weakening the sclera comprises reducing a thickness of the sclera in a region of the ciliary body without forming an opening completely through the sclera;
wherein weakening the sclera increases a working distance of a ciliary muscle of the eye.
3. A method, comprising:
irradiating at least a portion of a sclera of an eye to increase a diameter of the sclera overlying a ciliary body of the eye;
wherein irradiating at least the portion of the sclera comprises reducing a thickness of the sclera in a region of the ciliary body without forming an opening completely through the sclera;
wherein irradiating at least the portion of the sclera increases a working distance of a ciliary muscle of the eye.
