ABSTRACT:
This invention is a pre-formed intrastromal corneal insert. It is made of a physiologically compatible polymer and may be used to adjust corneal curvature and thereby correct vision abnormalities. The insert or segment may also be used to deliver therapeutic or diagnostic agents to the interior of the cornea or of the eye. The insert subtends only a portion of a ring, or "arc", encircling the anterior cornea outside of the cornea's field of view. The invention also includes a procedure for inserting the device into the cornea.
