This invention is a preformed intra-stromal corneal insert (812, 814). It is made of a physiologically compatible polymer and may be used to adjust corneal curvature and thereby correct vision abnormalities. The insert of segment (812,814-) may also be used to deliver therapeutic or diagnostic agents to the interior of the cornea, or of the eye. The insert (812, 814) subtends only a portion of aring 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.
