  1. Eye banking: cornealrecovery diego.ponzin@fbov.itThe Veneto Eye Bank Foundation, Venice • Workshop on Quality Systems in Ocular Tissue Banking, TAIEX 50564. • Zagreb, Croatia, 30-31 January 2013

  2. Corneal donation • Generation of the Unique Donation Code)

  3. Corneal recovery Donor maintenance: • Closed eyes, humidification(no ice / ointments / gauges) • Short post morteminterval • Corneal reflex stimulation: gauge, sterile physiologic • Low ambient remperature Ice on donoreyes Corneal reflex stimulation

  4. Corneal recovery • Consent, ascertainment of death, identification • Physical and in situ inspection • Disinfection of peri-ocular tissues, sterile field preparation • Disinfection and rinsing of ocular tissues • Excision/enucleation • Reconstruction • Medical-legal requirements

  5. Dressing • Personal Protective Equipment • Surgical scrub • Always work on a clean and tidy work surface

  6. Physical inspection of the donor (checking for evidence of parenteral drug use, and other high-risk behaviors for AIDS and hepatitis) • Put on personal protective clothing • A visual head-to-toe inspection of each eye donor should be performed, including the webs of fingers and toes, as well as the groin and behind the knees • Look for: • bruises • lacerations, scars, piercing • needle tracks not compatible with recent pathological anamnesis • fresh tattoos that may hide parenteral drug use, and other high-risk behaviors • and signs of transmissable diseases such as Kaposi sarcoma, swollen lymph nodes, skin rashes

  7. Procurement: recovery cases • 100% disposablematerial • 100% traceability

  8. Disinfection, rinsing, draping

  9. Peritomy, sclerotomy Sclerotomy and recovery: instrumentsdifferent from those for conjunctiva

  10. Sclerotomy NO! • Scleral rim ~ 4 mm • Regular cutting NO!

  11. Corneal-scleralrimdetachment(mostfrequentlyassociated to technicalerrors)

  12. NO! • Noinstruments in the AC • No tension, distorsion

  13. Reconstruction

  14. Labelling
