Rings and Arcs

KeraNatural sterile allograft rings and arcs were developed by VisionGift in our state of the art laboratories. Each ring and arc is processed in VisionGift’s ISO certified clean rooms to ensure safe and consistent grafts.

They are packaged using our patented sterilisation process for ease of use, and they come with a two-year shelf life so you don’t have to worry about timelines and lack of availability associated with fresh corneal tissue.

When it comes to keratoconus, KeraNatural is the clear choice.
