What is KeraNatural?

Allograft corneal ring implantation for keratoconus refers to a surgical procedure in which a small piece of corneal tissue (allograft) from a donor is implanted into the cornea of a patient with keratoconus. The corneal tissue or Keranatural product, which is human collagen, applied to the eye with keratoconus is safely packaged and sterilized at Visiongift Eye Bank in the USA.

Keranatural (Allograft corneal ring) is a small, semi-circular piece of collagen/cornea that is placed in the cornea to help reshape and improve vision. The procedure involves tunneling the cornea with a laser and inserting Keranatural into the corneal tissue. The ring helps to flatten the cornea, thickening the cornea, which can improve vision and reduce the need for or increase tolerance to contact lenses or glasses.

The allograft corneal ring is made from donated corneal tissue that has been processed and sterilized to eliminate any potential disease or infection. The procedure is typically done on an outpatient basis and patients may experience some discomfort or tenderness in their eyes for a few days after surgery. However, most patients can return to normal activities within a week or two after the procedure.
