Corneal ring implants are small rings of plastic that are embedded in the middle layer of your cornea, the clear, protective outer layer of the eye. These rings can help reshape and stabilize your cornea to improve vision and correct a variety of corneal conditions.

Implantation is most frequently performed when the patient is awake and has received anesthetic eye drops or injections to block pain. A small cut is made in the outer edge of your cornea and a small tunnel is made around the edge of the cornea. The ring is inserted in the tunnels and the cut is closed with sutures.

After surgery, you will probably go home the same day and wear an eye patch for a day or two. Antibiotic eye drops will be prescribed to avoid infection.
