	Slide 1. Lamellar dissection across the recipient cornea is begun using blade #1 (DORC International).
	Slide 2. The recipient lamellar dissection is extended using longer, curved blade #2.
	Slide 3. The recipient dissection is completed and extended to the limbus using the longest blade (#3).
	Slide 4. Scissors are used to excise a button of tissue from the posterior surface of the patient's cornea.
	Slide 5. The donor cornea is dissected on an artificial anterior chamber, using three blades of increasing length.
	Slide 6. The posterior portion of the donor button is folded over a layer of viscoelastic like a taco.
	Slide 7. The folded donor button is inserted into the recipient eye through a small clear corneal incision.
	Slide 8. The recipient endothelium is incised along the circumference of the area to be transplanted using a Sinskey hook.
	Slide 9. Descemet's membrane is scraped from the recipient cornea (lower left quadrant in this image) using a Melles scraper.
	Slide 10. Following removal from the eye, the recipient endothelium is laid on the surface of the eye to confirm that its size corresponds to the planned size of the donor button.
	Slide 11. The folded donor button is inserted into the eye.
	Slide 12. The folded donor button is positioned in the lower half of the recipient bed prior to unfolding inside the eye.
	Slide 13. After unfolding, the donor button is pressed up against the recipient bed by an air bubble injected into the anterior chamber.
