XENIA FOR KERATOCONUS
- PREVENTING CORNEAL
TRANSPLANTATION - STABILIZATION AND
VISION IMPROVEMENT
XENIA implants are used to avoid
corneal transplantation in patients with
keratoconus or to defer corneal
transplantation as long as possible.
The XENIA implant for keratoconus is crosslinked
and therefore significantly
stronger as compared to the
patient’s own …
XENIA FOR PRESBYOPIA
- MULTIFOCAL CORNEAL
IMPLANT - MADE FROM NATURAL
COLLAGEN
XENIA implants for presbyopia are
used to restore patients’ near vision
and eliminate their dependency on
reading glasses.
The XENIA implant for presbyopia is
less than 2mm in diameter and less
than 30µm in thickness. It is implanted
in a micro-invasive corneal pocket
created by …
What is XENIA?
The real thing …
XENIA is a corneal implant made of natural corneal collagen of animal (porcine) origin.
The XENIA material, natural corneal collagen, has been successfully validated by Mother
Nature – with a follow-up of more than 450 million years with excellent results.[1]
The XENIA material undergoes a special process to remove foreign cells including antigens.
This special process is called decellularization.
