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.

Surgery Description
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.
