Abstract
This implant is an intrastromal corneal insert ('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 insert. This insert design, when introduced into the stroma and properly adjusted there, permits at least partial correction of astigmatism in the eye.
