Abstract

An intrastromal corneal insert for effecting a change in the corneal curvature to treat conditions such as astigmatism, myopia, and hyperopia. The insert includes one or more arcuate or arc-shaped segments. The extent of corneal correction by such a segment, for a given cross-sectional configuration, is a function of one or more predefined parameters, including the arc angle, radius of curvature, cone angle, modulus of elasticity, and thickness of the segment. The invention also provides for various methods for changing the refractive characteristics of an eye. Generally, the methods involve determining the amount of corrective refraction desired, providing an intrastromal channel which traverses at least a portion of the circumcorneal rotation, and introducing one or more of the inventive segmented inserts.
