Keratolimbal allograft: Recommendations for tissue procurement and preparation by eye banks, and standard surgical technique

Purpose. To facilitate increased use of keratolimbal allograft transplantat ion (KLAL) for severe ocular surface disease (OSD) by informing clinicians and eye banks of differences in tissue requirements and preparation for the procedure and to describe the surgical technique of KLAL transplantation. Methods. The protocol of the Minnesota Lions Eye Bank is described for proc uring and preparing tissue for KLAL transplantation. The surgical technique is described in detail. Results. Over the last several years, we have modi fied our eye-banking procedures as well as our surgical technique to improv e the success of KLAL transplantation. Conclusion, KLAL transplantation for patients with severe ocular-surface disease is an important management opt ion. Success is influenced by the ability to obtain appropriate tissue; thi s requires clinicians and eye banks to expand current procurement guideline s.
