Customization
Customize your request with your preference for tissue thickness, age range, and cell count.
Tissue Shapes:
- Zip Zag
- Top Hat
- Mushroom
FLAK prepared tissue may promote the following improved results over traditional corneal surgery:
- Faster return of vision for your patient following surgery. The specialized corneal graft shapes provide a precise match for your recipient’s shape, and may require fewer sutures with less tension resulting in faster healing.
- Eliminates your risk of damaging donor tissue during preparation.
- Reduces post-surgical astigmatism. A precision-fit donor button along with less suture tension allows for a smoother corneal surface.

Shipping Expertise
Delivering tissue, on-time, the day of your scheduled surgery (unless requested earlier).
CorneaGen strictly adheres to safe shipping standards for local, national and international corneal tissue orders.
This starts with ensuring that tissue is packed appropriately in a container that maintains cooling for the duration of the shipment. The containers we use are inexpensive, but effective for transporting tissue to and from eye banks, surgeons and surgery centers.
We performed a study to validate our tissue shipping methods. Access the full report published in Cornea: The Journal of Cornea and External Disease, or read the abstract.
We ship tissue to arrive on the day you request delivery. Please order tissue at least seven days in advance of the scheduled surgery. Learn more on the Order Tissue page.
