Preloading since 2012

With the announcement of preloaded DSAEK, early adopters experienced the benefits and made the switch from preparing tissue intraoperatively to receiving tissue ready for transplant. The equipment, instrumentation, and supplies were no longer needed in the O.R. and the risk of damaging tissue was eliminated. Today, choose from multiple preloaded options for your DSAEK and DMEK cases.

TransplantREADY® Endo-In DMEK Preloaded in a Weiss Glass Cannula

  • The newest innovation in the LWVI TransplantREADY portfolio
  • TransplantREADY Endo-In DMEK allows graft to enter the AC oriented correctly
  • Endo-In configuration allows graft to unscroll without external tapping

“Teaching a paradigm shift in endothelial surgery”
— Leonard Heydenrych, MD

Dr. Leonard Heydenrych discusses” The use of Novel Injectable Tr-folded Endothelium-In DMEK in Cases of Complex Anterior Chambers” as presented at Cornea Forum, 2024

The DMEK Endo-In delivery system positions the DMEK graft with the endothelium on the inside of the scroll. As the graft is slowly introduced into the AC, it opens in an effort to return to its natural configuration of Endo-out.

  • Prepared using a no-touch hydro-dissection technique
  • Preloaded Endo-In using a tri-fold technique
  • Endo-In configuration allows graft to unscroll without external tapping
  • Significantly reduced endothelial cell loss; documented benefits include 10x less endothelial cell loss compared to dissection and staining with the SCUBA technique.
  • Time and expense saved in the O.R.

“Endo-in DMEK is the advancement in EK we have all been waiting for. It makes DMEK into a predictable procedure with less trauma to endothelial cells. This is the only way injectable DMEK should be done.”– Benjamin Lambright, MD – West Coast Eye Institute, Lecanto, FL

TransplantREADY® DMEK Graft Preloaded in a Weiss Glass Cannula

Each TransplantREADY DMEK graft is prepared using our Hydrodissection “Blister” Technique which simultaneously dissects and stains Descement’s membrane. The graft is prepunched to desired diameter, premarked with an “s” stamp or “I-II” peripheral marks and preloaded into the Weiss Glass Cannula. Endothelial cells are preserved by limiting tissue manipulation and exposure of endothelium to the Trypan Blue. Documented benefits include 10x less endothelial cell loss compared to dissection and staining with SCUBA.

  • Includes 14 French tubing and end-cap luer lock connector
  • Connects directly to a luer lock syringe
  • True no-touch prep using Blister Technique
  • Selective stromal staining limits exposure to Trypan Blue
  • Specular image post-prep of endothelium provided

TransplantREADY® DSAEK Graft Preloaded in a Weiss Glass Cannula

LWVI’s proprietary High-Pressure Anterior Chamber (HPAC) technique is used for preparing ultrathin DSAEK grafts. This method developed and introduced by LWVI in 2012 is reliable, accurate, consistently produces corneal grafts 40-70 microns and demonstrates less endothelial stress and cell loss. A proprietary trifold loading technique is used to safely secure tissue endothelial side in and maintain correct orientation during transport.

  • 2.8mm diameter delivery system
  • Delivers graft using fluid injection
  • Prepared and preloaded for no-touch delivery
  • Closed system provides deep stable chamber
  • Eliminates need for punch, forceps and A/C maintainer

“The TransplantREADY Endo-In DMEK delivery into the AC is streamlined saving time and expense in the OR. Unscrolling and positioning the graft in the AC takes 90% less effort and time than the traditional DMEK delivery device”

Craig Berger, MD Bay Area Eye Institute, Tampa, FL

“Endo-in DMEK is the advancement in EK we have all been waiting for. It makes DMEK into a predictable procedure with less trauma to endothelial cells. This is the only way injectable DMEK should be done.”

Benjamin Lambright, MD West Coast Eye Institute, Lecanto, FL

“Beautiful case. Opened up right away.”

Priya Mathews, MD, MPH

“Easiest and fastest DSAEK I’ve performed since 2007; the graft basically opened by itself. The graft looked like a million dollars POD1, not a single striae observed.”

Thomas A. Planchard M.D.

“Preloaded ultrathin DSAEK tissue in the Weiss Glass Cannula allows me to gently transfer tissue into the anterior chamber using a no-touch fluid injection technique and opens orientated correctly.”

Steven Kane, M.D.

“In a recent study performed with LWVI we demonstrated 4 times less endothelial cell loss using TransplantREADY DSAEK injection from a Weiss Glass Cannula compared to DSAEK pull-through using a Busin Glide and forceps insertion technique.”

Jason Miles, M.D.

“Using LWVI’s TransplantREADY DSAEK preloaded in a Weiss Glass Cannula allowed me to confidently perform my first DSAEK case ever, leaving the pre-cut and preload process of this delicate tissue to their expert processing services.”

Alejandro Candray, M.D. El Salvador

“Pre-punched PKP has been a welcome change to my practice. I can still provide the same surgical results without my surgery center having to stock every different size donor punch and recipient trephine”

Benjamin Lambright, MD West Coast Eye Institute, Lecanto, FL

“The assembly was easy to handle and intuitive to use. The preloaded nature also simplifies the surgical set up for DSAEK procedure.”

Simon Fung, MD

“Lions World Vision Institute made my transition to preloaded DMEK and DSAEK tissue seamless — the process is easy to learn and greatly reduces my surgical time. I also feel confident that the eye bank’s tissue preparation method preserves maximal endothelial cell density.”

Laura Palazzolo, MD
