Disclosed are devices and methods for delivering a sheet of tissue (506) into the eye in such a way that damage to the tissue is minimized, damage to the eye during insertion and manipulation of the tissue is minimized, and the tissue is released and delivered in a precise and controlled fashion.The device (100) includes a hollow handle portion (110) configured to convey a fluid (502) therein. The device also includes an injector portion (112) fluidically coupled to the handle portion and defining an internal channel (508) via which the fluid is conveyed. The injector portion includes a substantially flat tip (408) that defines an aperture connected to the internal channel of the injector portion and configured to enshroud a tissue for transplantation. When a vacuum pressure (510) is applied to the tissue via the fluid, the tissue is held in place within the tip aperture. When an injection pressure that is opposite in direction to the vacuum pressure is applied to the tissue via the fluid, the tissue is injected into the eye. |
