An intrastromal corneal ring segment (ICRS) (also known as intrastromal corneal ring, corneal implant or corneal insert) is a small device surgically implanted in the cornea of the eye to correct vision. Two crescent or semi-circular shaped ring segments are inserted between the layers of the corneal stroma, one on each side of the pupil,[1] This is intended to flatten the cornea and change the refraction of light passing through the cornea on its way into the eye.
