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. |

KLA |
Keratolimbal Allograft |
KLAL graft consists of a 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 is intended for use in procedures where a functional endothelium is not required. |
PKP |
Penetrating Keratoplasty |
Full-thickness donor cornea is used to replace the 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. |

BrightMEM |
BrightMEM is a corneal allograft to improve the conditions of the ocular surface. It has the following benefits:
- Permanent basement membrane (type IV collagen) that promotes corneal epithelial adhesion and corneal re-epithelialization.
- Natural collagen structure of BrightMEM is the basis for a highly-durable tissue that provides protection against stromal degradation.
- Environment more conducive to limbal epithelial cell survival, growth, and proliferation compared to other therapeutic options.

KeraNatural |
KeraNatural are available for your CAIRS procedure.
- Sterile allograft rings and arcs were developed to treat advanced keratoconus.
- A sterile allograft ring or arc is placed within the stroma to help reshape the cornea, reducing its irregular curvature and improving visual acuity.
- KeraNatural has a 2-year shelf life and the procedure is less invasive than a full-thickness transplant.
