Eye Bank Technical Advisory Group


The Eye Bank Technical Advisory Group (EBTAG) consisting of representatives of the European Eye Bank Association, Eye Bank Association of America, Eye Bank Association of Australia and New Zealand, Eye Bank Association of India, Asia Cornea Society, and the Pan-American Association of Eye Banks, have developed a global standard terminology to describe ocular tissue for transplant.

The group began meeting early in 2010 and agreed to the following goals:

  • Create and publish a nomenclature that will be endorsed by the professional groups represented;

  • Review the coding of this terminology within ISBT 128;

  • Agree on standardized labeling;

  • Determine if there is need for a consensus standard for ocular tissue;

  • Determine the mechanism for on-going maintenance of the terminology; and

  • Promote the use of ISBT 128 for ocular tissues.


The EBTAG is reviewing the current ISBT 128 ocular terminology to ensure its suitability with recent clinical developments such as DSAEK and DMEK procedures.


The committee is also revising the ISBT 128 Standard Labeling of Ocular Tissue v1.1.0 to ensure that the existing requirements are still appropriate. Furthermore, a new international joint statement on the terminology, coding, and labeling of ocular tissue is currently being drafted.


Since June 2022, the EBTAG Discussion Forum has been active in Loomio. The purpose of this forum is to provide an all-in-one platform where members can carry out discussions on proposed additions or changes to the ISBT 128 Standard and collaborate to reach a consensus.
