Corneal tissue

What is available right now, listed with the fields you judge suitability on.

Under South African law, human tissue is provided as a service. Evolution Vision charges a small administrative fee for that service.

Tissue is sourced through Lions World Vision Institute and Vision Share.

Process

How it works

Posted

Tissue is listed when ready to ship, with donor age, cell density, preservation time and expiry.

Reviewed

Every listing is public. You judge suitability from its fields before you contact anyone.

Enquiry

Enquire from the listing and its reference is attached. We answer the same day.

Donor record

The eye bank’s record, including serology, is sent to you after you enquire.

Placed

When the tissue is issued, the listing moves to Placed and comes off the board.

Glycerol preserved whole cornea and patch grafts, and amniotic membrane. Research corneas and globes, which are not for transplantation.

Donor age

In years.

Endothelial cell density

Cells per square millimetre, measured by specular microscopy at the eye bank. The primary suitability measure for endothelial keratoplasty.

Death to preservation

Hours between donor death and preservation.

Expiry

The date after which the tissue is no longer usable.

Intended procedure

DMEK, DSAEK, DALK, PKP, Boston KPro or tectonic. A guide rather than a restriction.

Status

Available or Placed.

Compliance

How this works, legally

Human tissue may not be traded as a commodity in South Africa. Listings carry clinical fields only, with no price, and tissue is requested by enquiry.

Available means the tissue is ready to ship. Placed means it has been issued. An enquiry starts a conversation about your case.

The National Health Act makes it an offence to sell or trade in tissue except as provided for in the Act. It permits a registered health care provider to receive remuneration for a professional service rendered. Evolution Vision’s administrative fee is a charge for that service.

Request tissue for a case

We answer every enquiry the same day, since tissue that is ready to ship is only held for a short time. If nothing on the board fits your case, tell us what you need and we will match it against what the eye banks have. If you are asking about a specific listing, open it and enquire from there so the reference comes through attached.
