Abstract
In one embodiment of the invention, an endothelial keratoplasty device includes a distal portion with first and second holes. A vacuum is applied, via the holes, to stromal tissue of donor ophthalmic tissue. This helps the corneal surgeon insert the donor tissue into the patient's eye and couple the donor tissue to the patient's tissue, all while limiting trauma to the endothelial cells of the donor tissue. Irrigating liquid may also be administered to the patient's eye via the aforementioned holes or additional holes, ports, or voids. The irrigating fluid may remove the need for use of an anterior chamber maintaining device. Also, a protective lip located on the distal portion of the device, or elsewhere, may help protect delicate endothelial cells on the donor tissue as the donor tissue is inserted into eye.
