What are corneal rings?
In the corneal ring segment treatment, we make an incision in the side of the cornea, place a tiny plastic ring inside the cornea to flatten its curvature, then close the incision. The ring treats mild nearsightedness and mild astigmatism in patients with very thin corneas, and may be used to treat a disorder called keratoconus. The rings are not visible to the patient or to others, and may be removed if necessary.
