Layers of the cornea are now able to be separated and selectively replaced, resulting in a stronger eye that is less likely to be lost due to trauma.

The cornea is the smallest transplanted body tissue; anything smaller is cellular. Despite its tiny size, modern transplant surgery has evolved to such a degree that all the separate layers of the cornea can now be selectively replaced, and layered transplantation surgery has advanced rapidly to become the gold standard in corneal transplantation.

The cornea is an optical structure lined on one side by skin and on the other side by cells. This makes it a fluid barrier (separating air from aqueous), a physical barrier, a support structure and a lens, yet it is just 0.5mm thick. The reason it can do all these things is because of its mixed embryological origins.

Layered transplantation can be broken down according to the major functional layers of the cornea:

1. Skin lining (epithelium)

2. Physical structure (stroma)

3. Fluid barrier (endothelial cells)
