Kera Rings

Kera rings are tiny plastic semicircular rings surgically implanted into the cornea to flatten the corneal surface and improve vision in patients with keratoconus.

Inserts can improve contact lens wear in most patients. They are not suitable for all patients with keratoconus.

Implantation does not affect the central optic zone, does not involve the removal of any tissue, and can be reversed if vision changes, thus preserving all future options for vision correction or adjustment.

How Kera rings work?

Imagine your cornea as a tent with a curved top. If you push out the sides of the tent, the top flattens. Similarly, when Kera rings are placed in the sides of the cornea, they flatten it just enough to correct keratoconus.
