Lions Eye Bank of Wisconsin performs approximately 1,200 donor recoveries each year.
LEBW also places more than 1,800 corneas for transplant annually. Tissue is prepared by experienced medical technicians, providing surgeons and researchers with the highest quality eye tissue in a variety of tissue types to fit your patient’s needs.
Processed Tissue
| Description | Click to Enlarge | |
|---|---|---|
| DALK | Deep Anterior Lamellar Keratoplasty
DALK graft consists of anterior layers of the donor cornea (epithelium to stroma). Recipient endothelial cells and Descemet’s Membrane are left in place. |
 |
| DMEK | Descemet’s Membrane Endothelial Keratoplasty
DMEK graft consists of isolated layers of the donor cornea (Descemet’s and endothelium). |
 |
| DSEK DSAEKUltra-thin DSAEK |
Descemet’s Stripping with (Automated) Endothelial Keratoplasty
DSEK graft consists of isolated layers of the donor cornea (stroma, Descemet’s and endothelium). Prepared by eye bank or surgeon. Ultra-thin: Customized thickness graft to meet predetermined tissue criteria. Between 60 to 200 microns thick. Prepared by eye bank. |
 |
| LAK | Laser Assisted Keratoplasty/Intralase Enabled Keratoplasty
LAK/IEK graft consists of a donor cornea that has been laser cut using a pre-programmed algorithm to make cuts at specific depths to create specific corneal shapes. Recipient cornea is cut using the same algorithm to precisely match donor cornea. |

Unprocessed Tissue
| Surgery | Description | |
|---|---|---|
| KLA | Keratolimbal Allograft | KLAL graft consists of full thickness cornea with an intact 2-4 mm skirt of conjunctiva attached at the limbus. |
| K-pro | Keratoprosthesis | Corneal tissue provided for inclusion in collar button design keratoprosthesis. |
| LKP (Tectonic) | Lamellar Keratoplasty Tectonic “patch graft”
For use in ocular procedures not requiring viable cells, such as glaucoma shunt coverage, injury repair, eccentric corneal ulceration and as a spacer for some models of keratoprosthesis. |
Fresh corneal tissue preserved in Optisol-GS, intended for use in procedures where a functional endothelium is not required. |
| PKP | Penetrating Keratoplasty | Full thickness donor cornea used to replace recipient cornea. |
| Long- Term Cornea | For use in ocular procedures not requiring viable cells, glaucoma shunt coverage, injury repair, eccentric corneal ulceration and as a spacer for some models of keratoprosthesis. | Preserved corneal tissue in glycerin, shelf stable for up to 2 years. |
| Sclera (whole & quarter only) | For use in ocular procedures not requiring viable cells, including glaucoma shunt coverage, injury repair, eccentric corneal ulceration, etc. | Preserved in ethyl alcohol, shelf stable for up to 2 years. |
