An implantation device can be used to facilitate implantation of a scleral prosthesis. The implantation device includes a first end portion configured to be inserted into a scleral tunnel of an eye. The implantation device also includes a second end portion configured to receive the scleral prosthesis. A rod with a tapered and rounded end can be partially inserted into the first end portion of the implantation device.
