Abstract
This invention is an intrastromal corneal ring ('ICR') which is not uniform in dimension. It has, typically, two or more raised areas (or areas of additional bulk) spaced apart from each other on the ring. This ring design, when introduced into the stroma and properly adjusted there, permits at least partial correction of astigmatism in the eye.
